Tips for including a class in a HTML document using jQuery?

I have successfully included my header and footer in separate HTML files using jQuery's .load() function. The jQuery code I used is shown below:

$(function(){
   $("#header").load("page-component/header.html"); 
   $("#footer").load("page-component/footer.html"); 
});

However, I am facing an issue where I cannot seem to add an active class to one of the header or footer links when navigating to another page. Can anyone provide assistance with this problem?

I attempted the following code but it did not work as intended:

$(document).ready(function(){
   jQuery('#menu-about').addClass('active');
});

Answer №1

Utilize the complete callback of the jQuery.load method.

.load( url [, data ] [, complete ] )

When you are using the addClass method for an element, the element may not yet be present in the DOM. The callback function is triggered when the external file is successfully loaded into the specified element.

$(function() {
  $("#header").load("page-component/header.html", function() {
    jQuery('#menu-about').addClass('active');
  });
  $("#footer").load("page-component/footer.html", function() {
    jQuery('#menu-about').addClass('active');
  });
});
