//导航3级栏目下拉
$(document).ready(function() {
$("#nav").superfish({
delay: 500,
animation: {opacity:'show',height:'show'},
speed: 'fast',
autoArrows: false,
dropShadows: false
});
});
$(function(){
$("#nav ul.third").each(function(){
var hasthird = $(this).find("li").size();
if(hasthird==0)
{
$(this).addClass("thirdNone");
}
})
})请高手帮忙
function addLoadEvent(func){
var oldonload = window.onload;
if (typeof window.onload != 'function') {
window.onload = func;
} else {
window.onload = function(){
oldonload();
func();
}
}
}
怎么修改啊？
