Assistance with Ajax for content loading

Greetings, I am encountering an issue with the following code snippet (located in a js file named ajax.js)

    $(function(){
      $("#loading").hide();

         $("ul#nav a").click(function(){
            page = "content/"+$(this).attr('href')

            $("#loading").ajaxStart(function(){
               $(this).show()
               })
            $("#loading").ajaxStop(function(){
               $(this).hide();

            })

            $(".content").load(page);
            return false;
         })
     })

Within index.php, at the beginning of the head section, I have included the necessary scripts

<script type="text/javascript" src="js/jquery-1.3.2.min.js"></script>
<script type="text/javascript" src="js/ajax.js"></script>

In the body section, there is a main menu navigation set up like this

<ul id="nav">
  <li><a href="page1.php">Here 1</a></li>
  <li><a href="page2.php">Here 2 </a></li>
</ul>

Furthermore, here is where the content is loaded

<div class="content">
  <img src="imgs/ajax-loader.gif" width="16" height="16" alt="Loading..." id="loading" />
  <?php include('content/page1.php'); ?>
</div>

While the above code functions as intended, my problem arises when I try to navigate within page1.php which contains:

<ul id="nav">
  <li><a href="page3.php">Here 3 </a></li>
  <li><a href="page4.php">Here 4 </a></li>
</ul>

This ultimately disrupts the entire system. The primary navigation links work fine, but upon trying links from other pages, the functionality breaks down. Even after attempting to load the ajax script on every page.php, the issue persists. Any suggestions or solutions?

Answer №1

Fixing the issue with the click event binding.

To ensure that the click event is bound properly, you must bind it to nav a as the content on page1.php is loaded via ajax and the click event is not being bound to new menu items.

To address this, create a new function named BindClickEvent:

function BindClickEvent(){
        $("ul#nav a").unbind( "click" );
        $("ul#nav a").bind("click", function(){
            page = "content/"+$(this).attr('href')

            $("#loading").ajaxStart(function(){
               $(this).show()
               })
            $("#loading").ajaxStop(function(){
               $(this).hide();

            })

            $(".content").load(page);
            return false;
         })
}

Call the BindClickEvent function during page load and within the content of page1.php. Whenever a menu item is added or removed, make sure to call the BindClickEvent function in the response from the ajax call.

One of the important aspects to consider is transferring functions, simply change

$("ul#nav a").click(function(){

to

$(document).on('click', 'ul#nav a', function(){

and your issue will be resolved :)
