Answer №1

To ensure that the Nav.html is successfully loaded, it is recommended to include a callback function in your load function. Here's an example of how this can be implemented:

$(function() {
    $("#nav-placeholder").load("Nav.html", function() {
        // Check if Nav.html was loaded
        // If successful, add the class
        $("#firstTag").addClass("active");
    });
});

Answer №2

It is likely that the #firstTag element is part of the content loaded through the AJAX request. In that case, make sure to place the addClass() function inside the callback of the load() method so that it runs only after the #firstTag is present in the DOM. You can try the following code:

$('#nav-placeholder').load('Nav.html', function() {
    $('#firstTag').addClass('active');
});
