Using Twig path to pass Ajax URL parameter

Question

Using Twig path to pass Ajax URL parameter

I'm facing an issue in my Twig view when passing parameters in the AJAX URL path. Since Twig is executed before JavaScript, it doesn't recognize the input value passed as a parameter. Is there a way to solve this without passing the param in data?

 <script type="text/javascript" charset="UTF-8">
(function($) {

    var $projectField = $('#project-field-container');

    $projectField.on('change', function() {
        var id_project = $(this).val();
        if('' != id_project) {
            $.ajax({
                url: {{ path('project_field', {'id_project': id_project})}},
                success: function (data) {
                    var content = $('select', data.contentHTML).html();
                    $projectField.html(content).trigger('change');
                }
            });
        } else {

        }
    });
})(jQuery);

If you're looking for a way to optimize your code, consider assigning the twig statement to a JavaScript variable prior to making the ajax call. Here's how you can do it:

var projectPath = "{{ path('project_field', {'id_project': id_project})}}";

Then, simply use

url: projectPath

in your ajax request for improved efficiency.

One way to enhance your code is by including the following:

data-url="{{ path('project_field', {'id_project': id_project}) }}"

This allows you to access the data in your JavaScript:

<script type="text/javascript" charset="UTF-8">

(function($) {

var $projectField = $('#project-field-container');

$projectField.on('change', function() {

    var url = $(this).data('url');

    $.ajax({
      url: url,
      success: function (data) {
            var content = $('select', data.contentHTML).html();
                $projectField.html(content).trigger('change');
            },
      error: function (data) {
            console.log(data);
        }
      });
    });
})(jQuery);
