Question

Jquery - Select Dynamic Elements

Asked by: socross

Hi

I am having issues selecting a dynamic element, can anyone offer any insight into why?

I have a simply ul which displays dynamic html generated by an onclick element in my page.

I am then trying to access these newly generated elements using normal JQ selectors but it wont work!! I have tried to provide a code sample below.

Many thanks

--s--

// THIS JQUERY UPDATES MY UL BASED ON THE ID OF THE BUTTON CLICKED, THE FUNCTION BUILDBUTTONS IS AN AJAX REQUEST TO GET THE NEW HTML
 
		// Generate Buttons (Ajax) Add to Page & Set Active State
		$('ul.pages-icons a').click(function() { //start function when any link is clicked
				
			//var current = $(this).parent("li").find("b").attr("class"); //retrieve id of link so we can use in php file		
			var current = $(this).attr("class"); //retrieve id of link so we can use in php file		
			
			if (current != "active") 
			{
				
		 		var page_id = $(this).attr("id"); //retrieve id of link so we can use in php file		
												   
				//Select this element
				$("ul.pages-icons li a.active").fadeTo("fast", 0).attr('class','off');
				
				// Set current Item Active"page_id="+page_id
				//$("ul.pages-icons-large li#recordsArray_"+page_id).attr('class','active');
				$(this).attr('class','active');
				
					$(".tools-icons").fadeOut(750, function() {
							buildbuttons(page_id);
							
					});
						
			  } // End If
				 
         }); //close click
         
 
// THIS IS THE CODE I USE TO SELECT NEW ELEMENT I NEED TO SELECT i have also tried binding the function to that element
 
 
      $('ul.tools-icons li#offline').click(function () {
			$("#responce").html('Item Clicked');
        ); 
        
        
        
// THIS IS THE HTML LI BEFORE REPLACMENT WHICH I CAN SELECT
 
<div id="tools-outer">
    <div class="table">
        <ul class="tools-icons">
            <li class="offline edit-page"></li>
            <li class="offline page-settings"></li>
            <li class="offline view-sub-pages"></li>
            <li class="offline take-online"></li>
            <li class="offline delete-page"></li>
            <li><a title="" href="javascript:void(0);" class="add-new-page">Add new page</a></li>                    
        </ul>
    </div>
</div>
 
 
// THIS IS THE HTML LI AFTER REPLACMENT WHICH I CANNOT SELECT
 
<div id="tools-outer">
    <div class="table">
        <ul class="tools-icons">
        <li><a title="Edit selected page" href="#" class="edit-page">Edit selected page</a></li>
        <li><a title="Edit selected page settings" href="#" class="page-settings">Edit selected page settings</a></li>
        <li><a title="View sub pages" href="#" class="view-sub-pages">View sub pages</a></li>
        <li id="offline"><a title="Take selected page offline" href="#" class="take-offline" id="8">Take selected page offline</a></li>
        <li id="delete"><a title="Delete selected page" href="#" class="delete-page">Delete selected page</a></li>
        <li><a title="Add new page" href="#" class="add-new-page">Add new page</a></li></ul>

When do you use the second code segment to select the newly added element?
Does the element exist in the DOM when the javascript is executed? From the looks of the source code you've shown I guess not. Please add a little more information about this so I can give you a better response!
(Real source code, with unnecessary segments removed would be the best, so I can try and debug it)

I assume it is not part of the Dom, does that mean I can't targetl it?

If you're using jQuery >= 1.3, you can use the Live event.
Documentation is here: http://docs.jquery.com/Events/live
Basically, it'll bind the function to an event of any dom entity that matches the selector, even if it's created some time later.

      $('ul.tools-icons li#offline').live("click", function () {
                        $("#responce").html('Item Clicked');
        );
