How can I make a button that sends me to another page that I specify? So far I've only been able to do it with the tag <a>and its href and target attributes. But I can't do it with a <button>.

When I want to generate a PDF with php and MySQL I get this error, which I don't know how to solve:

Fatal error: Uncaught Error: Call to undefined function mysql_connect() in C:\xampp\htdocs\codigoresponsive\codigonuevoappfish\opnpdf\reporte3_pdf.php:4 Stack trace: #0 {main} thrown in

I would like to create an HTML button that works as if it were a clickable link. When I press the button, I would like it to redirect me to a page. And I would like it to be as accessible as possible.

I would also like there to be no extra characters or parameters in the URL.

How can this be done?

From a String, "123-654321", what I want is to split it into two Strings:

string1=123
string2=654321

I need to be able to perform a query in which I must filter by dates, in which I have a start date and an end date and that the query returns results that are within the range of those two dates

As the title says, I want to limit the number of decimals that result from an operation with variables of type double, this result is displayed in a JTextArea of ​​a JFrame.

The code that does the operation and prints the result in the JTextArea is as follows: ( la, lband lcrepresent the sides of a triangle, acalculates the area and Ais the JTextArea where the result is printed).

if (lb+lc>la && la+lc>lb && la+lb>lc){
     a=Math.sqrt((la+lb+lc)*(-la+lb+lc)*(la-lb+lc)*(la+lb-lc)/16);
     p=la+lb+lc;
     A.setText("El triangulo es "+t+".\nEl area es ("+a+").\nEl perimetro es ("+p+").");

In Java you can use a for each loop by saying:

for (elemento e : array)

Also in jQuery:

$.each(arr, function() {

In JavaScript I know I can do:

for (var i = 0; i > 10; i ++)

But is there a way to do a for each in pure JavaScript?

Good afternoon people!. I have searched for half an hour and I have not found anything that works for me or gives me positive results. I have a pivot table that changes the number of rows to display based on what one selects from the DropDownList. The problem is that for those cases in which the table has few rows, the footer gets out of place and, as you can see below, it is not "stuck" properly to the footer.

I have tried with the position attribute, with others of which I had never heard but I can't get the footer to always stick to the footer. At the moment this is what I have in my css;

footer
{
    margin-top:50px;
    width:100%;
    height:200px;
    background-color:red;
}

From already thank you very much!

I am creating a mini game where the user tries to guess a name. But when I want to compare two text strings to see if they are the same it doesn't seem to work.

final String miNombre = "Jordi";
Scanner input = new Scanner(System.in);
System.out.println("Adivina mi nombre: ");

while (true) {
    String intento = input.next();
    if(intento == miNombre) {
        System.out.println("Acertaste!");
        break;
    } else {
        System.out.println("Intentalo de nuevo!");
    }
}

EXIT:

Adivina mi nombre: 
manuel
Intentalo de nuevo!
jordi
Intentalo de nuevo!
Jordi
Intentalo de nuevo!
