Maximizing the Potential of Return Values in JavaScript

I have a JavaScript code that retrieves information and displays it in a div. It's functioning properly, but I want to dynamically change the div id based on the returned data. For example:

function autoSubmit3() {
    $.post(
        'updatetype.php', 
        $('form[name="reportform"]').serialize(), 
        function (output) {
            $('#update').html(output).show();
        }
    );
}

Would be updated to,

function autoSubmit3() {
    $.post(
        'updatetype.php', 
        $('form[name="reportform"]').serialize(), 
        function (output) {
            $('#4update').html(output).show();
        }
    );
}

If the text "4: Type updated." is returned.

The target div would be

<div id="' . $Count . 'update"></div>

The content of 'updatetype.php' page would be

echo $Count, ": Type updated.";

Answer №1

If my understanding is correct:

function autoSubmit3() {
    $.post(
        'updatetype.php', 
        $('form[name="reportform"]').serialize(), 
        function (output) {
            var id = parseInt(output); // or any other desired value
            $('#' + id + 'update').html(output).show();
        }
    );
}

It may be more straightforward to use the nth-child and eq methods.

Answer №2

If you're in search of a solution, this could be the answer you need. (minus any AJAX complications)

PHP

$array = array(1, 2, 3, 4);
foreach ($array as $index => $value) {
    echo '<div id="' . $index . '_item">' . $value . '</div>';
}

Javascript

'use strict'
var index = 2; // find your specific index 
var id = '#' + index + '_item';
var element = $(id); // perform actions on it

Answer №3

"I am looking to create a dynamic div id based on the returned value"

To achieve this, you can use jQuery to update the id of the div like so:

$('#2update').attr('id',newNumber+'update');

You can see a basic example here
