Question

I loaded some HTML from another page via $.ajax:

<script type="text/javascript">
    $(function() {
        $.ajax({
            url: '/getInfo',
            context: $('#contentBox'),
            success: function(data) {
                $(this).html(data);
            }
        });
    });

    $(function() {
        $('#clickableElement').click(function() {
            alert("I work!");
        });
    });
 </script>

 <div id="contentBox"></div>

The code loads this HTML into the div with ID contentBox:

<p id="clickableElement">I'm clickable.</p>

However, when I click on the paragraph loaded, no alert box pops up. I don’t think I am accessing the DOM correctly when it comes to elements loaded via AJAX. How can I fix this?

Answer 1

$(selector).live(events, data, handler);                // jQuery 1.3+
$(document).delegate(selector, events, data, handler);  // jQuery 1.4.3+
$(document).on(events, selector, data, handler);        // jQuery 1.7+

on version:

$('#contentBox').on('click', '#clickableElement', function () {
    alert( 'I work!' );
});

on docs:

When a selector is provided, the event handler is referred to as delegated. The handler is not called when the event occurs directly on the bound element, but only for descendants (inner elements) that match the selector. jQuery bubbles the event from the event target up to the element where the handler is attached (i.e., innermost to outermost element) and runs the handler for any elements along that path matching the selector.
