Norak's questions

I have a generic object ( availableProducts), whose properties are arrays of objects of different types ( type1, type2, ...).

On the other hand I have a specific array of objects ( specificProducts).

I need that if an object of whatever type (contained in type1, type2, ...) does NOT exist with that IDin the specific array ( specificProducts), it is removed from availableProducts.

I have managed to do the opposite, that if it exists, I delete it, but the other way around, the verification is different, I have blocked myself and I do not know very well how to do that verification.

I put my code:

var availableProducts = {type1:[],type2:[],type3:[]};

product1 = {id:"8sdgs7dfgg7e", name:"A1", description:"desc1"};
product2 = {id:"h78sghfg7asd", name:"A2", description:"desc2"};
product3 = {id:"hay78d7887ss", name:"A3", description:"desc3"};
product4 = {id:"fa67dgshgfsc", name:"A4", description:"desc4"};

availableProducts.type1.push(product1);
availableProducts.type2.push(product2);
availableProducts.type2.push(product3);
availableProducts.type3.push(product4);

console.log("availableProducts antes", availableProducts);

var specificProducts = [];
productData1 = {ref:"001", id:"hay78d7887ss", brand:"brand1"};
productData2 = {ref:"002", id:"h78sghfg7asd", brand:"brand2"};
specificProducts.push(productData1);
specificProducts.push(productData2);

console.log("specificProducts antes", specificProducts);


for (var product in availableProducts){

    for (var i=0; i < availableProducts[product].length; i++) {

      for (var j=0; j < specificProducts.length; j++) {

        if (availableProducts[product][i] != undefined) {

          if (availableProducts[product][i].id == specificProducts[j].id) {

            console.log(availableProducts[product][i].id + " is the same as "+ specificProducts[j].id);

          } else {

            console.log(availableProducts[product][i].id + " is different as "+ specificProducts[j].id);
            availableProducts[product].splice(i,1);
            //delete availableProducts[product][i];
            //elimina todo y deja vacíos los arrays, cómo hago esto de otra forma??
          }

        }

      }

    }  
}

console.log("availableProducts después", availableProducts);

In the end, if they are different, it empties all the data as you can see, I imagine it is because in the for loop it checks one by one. I don't know how to fix this, thanks.

I am making a simple request to a web service that I have hosted on a hosting. If I try with postman, it returns a 200 and everything works fine, but I don't know what I'm doing wrong in my example. I leave you the code:

$(document).ready(function(){
	
	var url = 'https://www.dominiowebservice.com/miws/'
	var jsonData = {
		  "id": 23,
		  "datos": {
			  "nombre": "Nombre",
			  "email": "[email protected]",
			  "comentario": "Texto de mi comentario"
		  }
		}
	
	$.ajax({
        type: 'POST',
        url: url,
        data: jsonData,
        dataType: 'json',
        contentType: 'application/json',
		headers: { "Authorization": 'Bearer ' + 'lzoKSJorIm0rJEfTcsw'},
        success: function(response) {
          console.log('SUCCESS')
          console.log(response)
        }
    })
	
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

It returns the following error:

Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at https://www.dominiowebservice.com/miws/. (Reason: CORS preflight channel did not succeed).

How can I solve that? Is the error in my ajax request or in the web service itself? But I'm telling you that since Postman it has worked for me

I receive a json of data, which can contain one or more attachments, all of them are received in base64. I give you an example:

{
"id": 1,
"data": {
    "nombre": "Nombre",
    "file1": "Mhuc2dvCg==",
    "file2": "Yhj4dysYn==",
    "file3": "Jusj6Hism==",
    "file4": "Rhsy7Yhah==",
    ...
    }
}

I have managed to upload a file, but I don't know how to make it identify each one that arrives in the json. That is, if I do:

$adjunto1 = isset($input['data']['file1']) ? $input['data']['file1'] : '';

And after this I call the function subirFichero($adjunto1);everything works correctly. But how do I recognize all the files that arrive in the json, that is, check that if it starts with "file" it is an attached file and insert them?

I need to extract a substring from a string that meets a number of conditions . I have almost succeeded, but I have an error in the regular expression and I do not finish obtaining the desired result.

I receive a string, with a long name of a rate, along with a letter and version number. For example: "NAME RATE V1 12M". I need to keep only the "V1" part.

It will always follow the pattern: - A letter (in principle capitalized, although I would like to accept both), in my case it will always be the letters: V, L, M. - Always followed by a number that starts at 0 and can be up to 2 digits . Here I have my problem, when it is a figure, it extracts the substring correctly, when it is 2 figures it fails and it does not extract it, it does not find a match.

I leave you what I have so far with some examples included:

$var1 = "TARIFA 1.1 NOMBRE TARIFA V1 12M";
$var2 = "TARIFA LDVB8 NOMBRE V5 10M";
$var3 = "TARIFA HD76 V10 12M";
$var4 = "TARIFA NOMBRE4 L3 18M";
$var5 = "TARIFA NOMBRE5 L10 12M";
$var6 = "NO HAY COINCIDENCIA";
$var7 = "TARIFA NOMBRE7 M6 12M";

function extractV($str) {
    if (preg_match('/ [V|L|M][0-9]? /',$str,$coincidencias,PREG_OFFSET_CAPTURE)) {
        //Hay coincidencia
        $valorBuscado = $coincidencias[0];
        $version = $valorBuscado[0];
    } 
    else 
    {
        $version = "NO";
    }
    return $version;
}

$extraccion1 = extractV($var1);
echo "<br>Coincidencias1 = ". $extraccion1;

$extraccion2 = extractV($var2);
echo "<br>Coincidencias2 = ". $extraccion2;

$extraccion3 = extractV($var3);
echo "<br>Coincidencias3 = ". $extraccion3;

$extraccion4 = extractV($var4);
echo "<br>Coincidencias4 = ". $extraccion4;

$extraccion5 = extractV($var5);
echo "<br>Coincidencias5 = ". $extraccion5;

$extraccion6 = extractV($var6);
echo "<br>Coincidencias6 = ". $extraccion6;

$extraccion7 = extractV($var7);
echo "<br>Coincidencias7 = ". $extraccion7;

As you can see, in the $var3and $var5, it does not extract value (because the number that follows the letter is 2 figures), but it should. How can I correct the RegEx? Or any solution for substring extraction with those features? Thank you!

I have a small script where I want to insert a new column to a database table.

This is the content of the file myscript_ddl.sql:

START TRANSACTION;
ALTER TABLE e1qxp_productos ADD COLUMN `cierre_venta` TINYINT(4) NULL DEFAULT NULL;
COMMIT;

And to execute it I do it by command line as follows:

mysql -u usuario -pclave nombrebasededatos < myscript_ddl.sql

It throws me the following error and it won't let me add the field:

ERROR 1067 (42000) at line 2: Invalid default value for 'start_date'

I have tried it manually from PhpMyadmin and the exact same thing happens, the same error. It also refers to the fact fecha_iniciothat it is another column in the database that should not have anything to do with the new insertion.

For what is this? How can I solve that?

Edit: I add the definition of the table

CREATE TABLE `e1qxp_productos` (
  `id` int(11) UNSIGNED NOT NULL,
  `state` tinyint(1) NOT NULL,
  `nombre` varchar(255) NOT NULL,
  `apellidos` varchar(255) NOT NULL,
  `nif_cif` char(9) NOT NULL,
  `direccion` varchar(100) NOT NULL,
  `ciudad` varchar(100) NOT NULL,
  `provincia` varchar(100) NOT NULL,
  `cp` varchar(100) NOT NULL,
  `tipo_cliente` enum('persona','empresa') DEFAULT 'persona',
  `tipo_producto` tinyint(1) DEFAULT '-1',
  `fecha_inicio` timestamp NOT NULL DEFAULT '0000-00-00 00:00:00',
  `fecha_fin` timestamp NOT NULL DEFAULT '0000-00-00 00:00:00',

  `marca` varchar(255) DEFAULT NULL,
  `enviado` tinyint(1) NOT NULL DEFAULT '0',
  `process` varchar(100) DEFAULT NULL
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

I am trying to collect a string that returns a .php file by making an Ajax call. But it always goes into success, however the data it returns is always null. For what is this?? I'm learning and I don't know very well what I'm doing wrong...

The code I have tried:

jQuery.ajax({
                url: '/administrator/components/views/response.php',
                method: "POST",
                dataType: "json",
                data: {
                    request: result.id
                }
            }).success(function (data) {

                console.log("Success. Data: "+ data);

            }).error(function (error, responseText) {
                console.log("Error. "+ error);

            });

The response.php file only contains:

return "Texto de prueba";

Actually I need the .php file to do some calculations and return them, but first I need to solve the problem that it doesn't even return some example...

I made a mergebranch to master and later I realized that this branch had changes that I didn't want.

I've uncommitted that one mergewith:

git revert -m 1 commit_hash

Now I need to merge that branch back to master and it won't let me. It looks like it's already merged, but the changes don't show up in master. It tells me the message: " Already up-to-date." when trying to merge again.

Does anyone know what's going on? How can I merge that branch again?

edit:

• In the master branch, after this some more commits have been made
• In my branch (in which I have the problem when merging) no commit or new change has been made

I have a URL on my website:https://www.miweb.com/componente/nombre/contratar

I would like it not to show "name" since the company has changed, but that the URL continues to lead to the same place, otherwise the hiring does not work.

Is it possible to show the user a URL but point to the real one?

I have done it this way in the .htaccess file with mod_rewrite, but it only redirects me and of course, I get a 404 error.

RewriteEngine On
Rewritebase /

<IfModule mod_rewrite.c>
    RewriteRule ^componente/nombre/contratar$ http://%{HTTP_HOST}/componente/contratar$1 [R=302,L]
</IfModule>

How can I solve that?

I have this url to access a study within the web:

http://miweb.com/index.php?option=com_component&view=estudio&factura=1&id=25977&token=8f8c54a3ce165332fd59f17

I want a URL similar to the following to redirect to the previous one

http://miweb.com/estudio&factura=1&id=25977&token=8f8c54a3ce165332fd59f17

That is, replace part of the URL, but keep the rest of the parameters.

So far, I've edited mod_rewrite in the .htaccess file and got it to replace strings (for example com_component), but not string index.php?option=com_component&view=estudio. This gives me an error, is it because of the ?&=?

RewriteEngine On
Rewritebase /

<IfModule mod_rewrite.c>
    RewriteCond %{QUERY_STRING} (.*)com_component(.*) [NC]
    RewriteRule (.*) $1?%1nuevostring%2 [R=302,L]
</IfModule>

How can I replace the entire line index.php?option=com_component&view=estudiowith one word (eg "study")?

edit:

Is it possible that the URL with all the parameters is served in the URL, but the part does not appear index.php?option=com_component&view=estudio? I don't want the user to see the name of option and view, but instead they are parameters that I need for the URL to work

I have this URL in some of the sections of my website in Joomla:

http://miweb.com/index.php?option=com_component&view=contracts&ff=1&id=20977&token=8f8c54a3ce165332fd59f17319ba

The point is that I don't want users to see the name: com_componentwhen they access from the link. I need to replace it with another string

com_component --> com_nuevonombre

I have edited the .htaccess file, activating mod rewrite and I have this:

RewriteCond %{QUERY_STRING} ^(.*)com_component(.*)$
RewriteRule ^(.*) $1?%1com_newname%2 [R=301,L]

I have almost achieved what I want, it replaces the string, but the error I have is that it adds the local path to my project in front of it. How can I correct it? I also accept other solutions if they occur to you.

The url that shows me after the error is something like this:

http://miweb.com/var/www/html/miweb/index.php?option=com_nuevonombre&view=contracts&ff=1&id=20977&token=8f8c54a3ce165332fd59f17319ba

I'm making a little game of a drawing palette working with the JavaScript DOM. I want clicking on each div with a background color to select that color.

I don't know what I'm doing wrong, because when accessing the property style.backgroundColor, it doesn't return any value, how can I access the backgroundColor of the div I click on?

My code is the following, you can run it to see what I say. I show it in some "alert" so that it is better understood.

Hello everyone, I'm having problems with Google Chrome and autocomplete. I want some fields of my form not to be autocompleted and I have added the attribute:autocomplete="off"

This in Chrome is not working, but in other browsers like Firefox it is. How can I prevent only some fields from being filled in?

I have seen on the internet as an alternative solution to add autocomplete="off"to the label <form>, but this does not work for me, since I would like many fields to be autocompleted...

<form id="formulario" action="" method="">
<input type="text" name="nombre" placeholder="Nombre..." />
<input type="text" name="apellidos" placeholder="Apellidos..." />
<input type="email" name="email" placeholder="Correo electrónico..." />
<input type="text" name="codigo" placeholder="Código promocional..." autocomplete="off" />
</form>

How do I prevent a single input field from autocompleting in Chrome?

Within my project I am performing some tasks in a branch (branch_A), which was branched from the main branch of the project (master). Now I need to create a new branch, born from branch_A (say branch_A_branch)

How can I create a new branch from another already created with commands?

When I work from master, I do the build with:

git checkout -b "rama_A"

Would it be correct to place myself in branch_A (in this case I am already with -b) and from there do the same step?

It would be:

git checkout rama_A
git checkout -b "rama_A_ramificación"

And one last thing, to later merge these two branches (branch_A and branch_A_branch), that is, save the changes from branch A to branch_A itself, how should I do it? I am right?

I need the different regions or "islands" made up of 1s within an array of any dimension to be separated. My example seemed to work correctly but there are some "special" cases like the following that don't work well. It should detect 2 elements or regions and yet it gets "confused" and finds 3 (when the 2 and 3 should be the same). You can run the example to see more clearly what I explain.

var matrix = [
    [0, 0, 0, 0, 0, 0, 0, 0, 0, 0],
    [0, 1, 0, 1, 1, 1, 1, 0, 0, 0],
    [1, 1, 0, 1, 0, 0, 0, 1, 0, 0],
    [1, 0, 0, 1, 0, 0, 0, 1, 0, 0],
    [0, 0, 1, 1, 0, 0, 0, 1, 0, 0],
    [0, 0, 0, 1, 0, 0, 0, 1, 1, 0],
    [0, 1, 0, 1, 0, 0, 0, 1, 1, 1],
    [0, 1, 0, 1, 1, 0, 0, 1, 1, 0],
    [0, 1, 1, 1, 1, 1, 1, 1, 0, 0],
    [0, 0, 0, 0, 0, 0, 0, 0, 0, 0],
];

var contFilas = matrix.length;
var contColumnas = matrix[0].length;
var canvas = document.querySelector("canvas");
var ctx = canvas.getContext("2d");
var sz = 20;
var regions = [];
var regionCollection = [];

canvas.width = sz * contColumnas;
canvas.height = sz * contColumnas;
ctx.fillStyle = "silver";
ctx.fillRect(0, 0, canvas.width, canvas.height);

for (var y = 0; y < contFilas; y++) {
    var regionline = [];
    regions.push(regionline);

    for (var x = 0; x < contColumnas; x++) {
        var pixelRegion = 0;
        regionline[x] = 0;
       


        if (matrix[y][x] === 1) {
            // check previous row
            if (y) {
                if (matrix[y - 1][x]) {
                    pixelRegion = regions[y - 1][x];
                } else if (x && matrix[y - 1][x - 1]) {
                    pixelRegion = regions[y - 1][x - 1];
                } else if (x + 1 < contColumnas && matrix[y - 1][x + 1]) {
                    pixelRegion = regions[y - 1][x + 1];
                } 
            }

            // check current row
            if (x && matrix[y][x - 1]) {
                pixelRegion = regions[y][x - 1];
            }

            // if not connected, start a new region
            if (!pixelRegion) {
                regionCollection.push([]);
                pixelRegion = regionCollection.length;
            }
            // remember region
            regionline[x] = pixelRegion;
            regionCollection[pixelRegion - 1].push([x, y]);

            // paint it
            ctx.fillStyle = "black";
            ctx.fillRect(x * sz + 1, y * sz + 1, sz - 2, sz - 2);
        }


        ctx.fillStyle = "white";
        ctx.fillText(pixelRegion, x * sz + 8, y * sz + 13);

    }
}

How can I correct this? I can't solve the error... It could be solved with a recursive function that calls the traversal of the matrix to check in each coordinate if it has 1s around it (up, down, left, right and diagonals). I'm stuck and I don't know how to fix the error

I have to save the difference of X files (pages of a pdf) and I need the differences of that page to be saved in each array (one per page).

I have managed to generate empty arrays dynamically, but my problem is how to push those arrays dynamically as well?

The content that must be "dynamic", since I don't know the total number of pages can vary, is that of the nested if that I show in the code:

    //genera dinámicamente los arrays en los que se guardaran diferencias de cada página (el número total de páginas es allPages.length)

    for (i=1; i<=allPages.length; i++) {
        eval("diffPage"+i+"="+"[]");
    }

    var pairs = []; //Ej. var combinations = ["texto1","texto2","4"];

    for (var x=0; x<pairs.length; x++){

        var diff = recognizeTerms(comb[x], 5, 50); //diferencias de todas las combinaciones posibles

        for (y=1; y<allPages.length; y++) {

            for (z=0; z<diff.length; z++) {

                //A partir de aquí:
                //¿Hay alguna manera de hacer este guardado en arrays dinámico?
                //Ya que se deben guardar las diferencias de cada página en un array

                if (combinations[x][2] == 1) {
                    if (diffPage1.includes(diff[z]) == false) { //comprueba que el string no existe ya en el array de diferencias
                        diffPage1.push(diff[z]);
                    }
                } 
                if (combinations[x][2] == 2) {
                    if (diffPage2.includes(diff[z]) == false) {
                        diffPage2.push(diff[z]);
                    }
                } 
                if (combinations[x][2] == 3) {
                    if (diffPage3.includes(diff[z]) == false) {
                        diffPage3.push(diff[z]);
                    }
                } 
                if (combinations[x][2] == 4) {
                    if (diffPage4.includes(diff[z]) == false) {
                        diffPage4.push(diff[z]);
                    }
                }

                //sucesivos if ... (tantos como números de página haya), por ello necesito que sean dinámicos esos if
            }

        }

    }

I want to match all the elements of the same array with each other, but an element cannot be matched with itself.

The code I got is the following:

        function combine(list) {

        var pairs = new Array((list.length * (list.length - 1)) / 2),

        pos = 0;

        for (var i = 0; i < list.length; i++) {

            for (var j = i + 1; j < list.length; j++) {

                pairs[pos++] = [list[i], list[j]];

            }

        }

        return pairs;

        }

    var result = combine([1, 2, 3, 4]);
    console.log("Combinaciones = "+ JSON.stringify(result));

The result I expect as a solution will be:

Combinaciones = [[1,2],[1,3],[1,4],[2,1],[2,3],[2,4],[3,1],[3,2],[3,4],[4,1],[4,2],[4,3]]

However I get this and I don't know where the error is:

Combinaciones = [[1,2],[1,3],[1,4],[2,3],[2,4],[3,4]];

So for example if it checks 1.2 I also want it to check 2.1 but not each number with itself.

How to obtain the combinations of possible pairs in both senses, only omitting the one of a number with itself?

I am using a JSON to validate data from a series of invoices. First of all, I have removed all the spaces from the data, and then I validate the fields according to the definition found in a JSON. It has served me perfectly, but now I find myself with a small problem:

If you wanted to validate the text:

Total electricity €54.60

I did it this way:

"regexp": {
          "productType": "Electricidad",
          "electricityTotal": "Totalelectricidad([\\d\\,\\.]+)€"
}

But I want to validate invoices in Basque, Catalan...etc. I don't know how to make it filter the following text:

Argindarra guztira / Total electricity €54.60

My problem is how to make it include the slash "/" and take it as part of the string, since it is the only thing that changes in the expression.

I want the character to be recognized "/"as part of the string, for example:

"regexp": {
          "productType": "Electricidad",
          "electricityTotal": "Argindarraguztira/Totalelectricidad([\\d\\,\\.]+)€"
}

In this case it gives me an error, because I need to include something in the expression so that it admits the "/".

I'm starting with Javascript and I still don't handle the asynchronous theme well, promises... etc

The issue is that within a callback I need to access the data of an array (go through it using a for) and this throws me an error that I don't know how to fix.

My code:

var objetoQueGuardo = {'event': 'evento1', 'label': 'valor'};
var dataLayer = [];
dataLayer.push(objetoQueGuardo);

factura.createFactura(id, false, token)
                .then(function successCallback(response) {

            for (var i = 0; dataLayer.length; i++) {
                dataLayer[i].label;
            }

}, function errorCallback(response) {
                    console.warn(response);
});

I have shortened the code a bit, to make the example simpler. The content of dataLayer is an array of objects and I want to keep the label attribute of each one.

The error it shows me:

 TypeError: dataLayer[i] is undefined

 Possibly unhandled rejection: {}

I just started in the world of Javascript and I have doubts...

I have the following function, I want it to repeat as long as the random value is 204. When the code is 200 it should stop, if it is 500 notify error and stop too. The request will be repeated every second (hence the use of setInterval although I don't know if I'm doing it correctly)

I also want it to try X times and also stop... I don't know how to implement it, could it be with a counter?

var myArray = [200, 500, 404, 204];
var encontrado = false;
var cont = 0;

var repeticion = setInterval(function aleatorio() {

  var rand = myArray[Math.floor(Math.random() * myArray.length)];


  if (rand == 200) {
    console.log("HTTP 200! Encontrado!");
    encontrado = true;

  } else if (rand == 500) {
    console.log("HTTP 500! Error interno del servidor");
    encontrado = true;

  } else if (rand == 204) {
    console.log("HTTP 204!");

  } else if (rand == 404) {
    console.log("HTTP 404!");
  }

  cont++;

  if (encontrado === true) {
    stopFunction();
  }

}, 1000);

function stopFunction() {
  clearInterval(repeticion);
}

It is a small simulation, since this will later work with real responses from a server and with another function.

I tried to do all this with a do-while, but logically the timer theme was not supported. If anyone knows how it also serves as a workaround.

How can I optimize my code and fix what is missing? Thank you

After calling a web service, it returns this data to me in json format.

I need to take the numeric value of $value and store it in a variable. I am working with JavaScript. Thank you

Here the json:

 {"return":{"attributes":{"xsi:type":"xsd:int"},"$value":115822961}}
