我发现了一个与我的问题类似的问题，但答案对我不起作用。我有一个在网上找到的与 JQuery 一起使用的导航。
我将导航执行脚本放在一个外部文件中并链接它，但现在它不起作用。有人可以解释为什么它不起作用吗？我还尝试了 $(document).ready( 也不起作用的函数。
我把对文件的引用放在头上
我已经更新了我的 Javascript，这也不起作用
$(document).ready(function() {
$(function() {
$('#hn_menu > li').bind('mouseenter',function(){
var $elem = $(this);
$elem.find('img')
.stop(true)
.animate({
//'width':'170px',
'width':'120px',
//'height':'170px',
'height':'120px',
'left':'0px'
},400,'easeOutBack')
.andSelf()
.find('.hn_wrap')
blah blah blah
});
});
这是整个文档..我需要将这个混乱转换为外部文件脚本
