select dynamically added element with jquery...

I have dynamically added an element in page using jquery with following function.

function addtocar开发者_C百科t(popid)
{
    jQuery('#thumb'+popid+' button').attr("disabled", true);
    //jQuery('#thumb'+popid+' button').html("Added");
    position = jQuery('#cart').offset();
    source = jQuery('#thumb'+popid+' img').offset();

    jQuery('#thumb'+popid+' img').clone().css({'display':'block', 'position':'absolute','top':source.top,'left':source.left}).appendTo('body').addClass('animation');
    jQuery('.animation').animate(
        {'left': position.left, 'top':position.top},
        'slow',
        function(){
                jQuery(this).remove();
                jQuery('#cart').append('<li class="test">'+jQuery('#thumb'+popid+' .title').html()+'<a href="#">X</a></li>');
                jQuery.ajax({
                    url: "creatives.php?ajax=1&creativeid="+popid,
                    success:function(data){
                        jQuery('.itemstodwnload span').html(data);
                    }
                }); 
            }
        );
}

but i cannot call any event on this new element.

jQuery('.test').hover(function(){
            alert('asdf');
        });

any suggestion

when you set the event handler by doing

jQuery('.test').hover(function(){
            alert('asdf');
        });

you're doing just once (the browser set that function as event handler for all the object with "test" class present at the time of executing this line. To have an handler setted for every "test" element, you should use intead

jQuery('.test').live('hover', function(){
            alert('asdf');
        });

You must use the live() function to attach events to elements added to the DOM after page loading.

try

jQuery('.test').live('hover', function(){
            alert('asdf');
        });

This is because events are attached to elements usually when DOM it's ready and if you add elements afterwards they have no events attached. Live() uses event bubbling to work around this.

Try

jQuery(".test").live({
    mouseenter:
       function()
       {

       },
    mouseleave:
       function()
       {

       }
   });

to bind an event on dynamically created element, jquery provides fallowing two functions to acomplish this-

1. delegate
2. live

you can use delegate in same way as i have used live

jQuery('.test').live('hover', function(){             
              alert('asdf');        
     }); 

Advantage of delegate over live is that you can do chaining in delegate but not in hover.
