HTML/jQuery/CSS Drop Down Menu Issue / Safari_问答_开发者

I have a drop down menu that is coded in HTML, CSS, and jQuery and it works fine in Firefox and IE but not in Safari, and also not in Firefox on Mac.

The drop down displays inline as opposed to list-item for the drop down in Safari.

Any ideas why?

<html>

<head>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.4/jquery.min.js"></script>

<script type="text/javascript" >

$(document).ready(function(){
        $('#menu li').hover(
            function() {
                //$('ul', this).css('display', 'block');
                $('ul', this).fadeIn(200); 
                var src = $('img.item', this).attr('src').match(/[^\.]+/) + '_over.png';
                $('img.item', this).attr('src', src);
            },
            function() { 
                //$('ul', this).css('display', 'none'); 
                $('ul', this).fadeOut(350);
                var src = $('img.item', this).attr('src').replace('_over', '');
                $('img.item', this).attr('src', src);
            });
});

I think your selector is messed up on the hover event. I debugged here: http://jsfiddle.net/brianflanagan/Spc2M/

Basically I changed $('ul', this).fadeIn(200); to $(this).find('ul');

Hope this helps.
