PlayerWet's questions

I have a problem with an Ajax request . I don't know if I'm doing it correctly, the fact is that I've always done it with the Jquery library , but now I want to do it only with Javascript .

Code

var enviarObjeto={'titulo': 'hola','usuario': 'Pier'};
var objeto = "json_name=" + JSON.stringify(JSON.stringify(enviarObjeto));
var xhr = new XMLHttpRequest();
xhr.open('POST', "guardar.php", true);
xhr.setRequestHeader("Content-Type", "application/x-www-form-urlencoded");
if (xhr.status == 200) {
   xhr.send(objeto);
   xhr.onload = function () {
   alert(this.responseText);
 };

alert('enviado ok');
} 
else {
    alert('error');
}

Can you tell me what I have done wrong? It is the first time that I do it with Javascript and I would be grateful if you tell me where my errors are.

I have a problem, I have never used Sublime Text and I would like that when editing a php file, pressing for example the f12 key from sublime, it would open in localhost (Chrome). But I can't do it.

I have the wanpserver active and the address of my project is:

http://localhost.test/

I have installed the View in browser plugin and I manage to open the file with Chsome, but it does it from a relative path and not from my php server with localhost.

Apparently you have to configure the routes of my project. I have read on several sites that it is done in Project -> Edit Project URLs but that option does not appear in the Project menu.

Please see if I'm doing something wrong, I have installed Sublime Text 64. Why doesn't that option appear? did I miss something?

I am forced to change the URL of some pages of my site, but the problem I have is that if I do, I will lose the comments from comment boxFacebook.

Is there a way to change the URL so that the comments comment boxpoint to the new URL?

This is the code of comment box:

<div id="fb-root"></div>
<script>(function(d, s, id) {
  var js, fjs = d.getElementsByTagName(s)[0];
  if (d.getElementById(id)) return;
  js = d.createElement(s); js.id = id;
  js.src = "//connect.facebook.net/es_ES/sdk.js#xfbml=1&version=v2.8&appId=93773124298xxxx";
  fjs.parentNode.insertBefore(js, fjs);
}(document, 'script', 'facebook-jssdk'));</script>


<div class="fb-comments" data-href="https://www.example.com/" data-numposts="5"></div>

It turns out that I have a menu that I want, as the scroll arrives, to remain fixed on the screen.

He does it well, but when he arrives he starts blinking, takes off and goes crazy.

$(window).scroll(function(){

    var sticky2   = $(".conte-botk")[0].getBoundingClientRect().top + $(window)['scrollTop']();  


    var sticky = $(".conte-botk");

    var scrolle = $(window).scrollTop();



  if (scrolle > sticky2) {

        sticky.addClass('fixed');

  }else{

        sticky.removeClass('fixed');

    } 


});

I have tried removing the sticky2 variable from the scroll function and the problem is solved, but it stops being accurate when resizing the browser window. Could someone give me a solution?

It turns out that I have a function that uploads an image to the server, but sometimes it takes too long and I would like to be able to cancel said function using a cancel button.

$('#imageUploadForm').on('change',(function(e) {
        e.preventDefault();
        var formData = new FormData(this);

        $.ajax({
            type:'POST',
            url: $(this).attr('action'),
            data:formData,
            cache:false,
            contentType: false,
            processData: false,
            success:function(data){
                console.log("success");
                console.log(data);
            },
            error: function(data){
                console.log("error");
                console.log(data);
            }
        });
    }));

How could the user stop it with a click?

Is it possible to include html code before the anchor text and would it harm the search engine's crawler to read it?

It is that I need the link to have a certain width, which is not limited by the size of the text.

 <a href="/cine.php"><div class="3d-cine">
    <div class="text-3d-cine">CINE</div>
  </div>
 </a>

As you can see, the anchor text is inside a div, and this at the same time is inside another div, and outside is the link that leads to the site.

The same is a silly question, but I have never encountered a similar problem, I have always placed the anchor text inside the link and never in this way. Would search engines have problems?

It turns out that I need to hide some text but only on the mobile version, I would like it to be visible on the desktop version only. It is that in the desktop version the text can be placed thanks to the higher resolution, but in the mobile version I have to place it below and it takes up too much space.

I don't know if Googlebot (or other search engines) takes into account all these things, or only what is shown on the desktop version

Would it be detrimental to the SEO of the page? Thank you very much.

I have a form that uploads a photo to my website, made with php (come on, a typical form that uploads a photo).

<form action="upload.php" method="post" enctype="multipart/form-data">
    Select image to upload:
    <input type="file" name="fileToUpload" id="fileToUpload">
    <input type="submit" value="Upload Image" name="submit">
</form>

And on the server:

<?php
$target_dir = "uploads/";
$target_file = $target_dir . basename($_FILES["fileToUpload"]["name"]);
$uploadOk = 1;
$imageFileType = pathinfo($target_file,PATHINFO_EXTENSION);

// Check if image file is a actual image or fake image
if(isset($_POST["submit"])) {
    $check = getimagesize($_FILES["fileToUpload"]["tmp_name"]);
    if($check !== false) {
        echo "File is an image - " . $check["mime"] . ".";
        $uploadOk = 1;
    } else {
        echo "File is not an image.";
        $uploadOk = 0;
    }
}
?>

The fact is that I would like that if someone sends a file, through php code I would be notified on my Android smartphone.

Is there any way?
