1.布局：
<div> <img src="~/images/head_icon.png" /> <div id="profileMenu"> <ul> <li> <a href='#'> <span>修改密码</span> </a> </li> <li> <a href='#' ><span>退出</span></a> </li> </ul> </div> </div>
2.js控制：
function dropMenu(obj) { $(obj).each(function () { var theSpan = $(this); var theMenu = theSpan.find(".drop"); var tarHeight = theMenu.height(); theMenu.css({ height: 0, opacity: 0 }); var t1; function expand() { clearTimeout(t1); //theSpan.find('a').addClass("selected"); theMenu.stop().show().animate({ height: tarHeight, opacity: 1 }, 200); } function collapse() { clearTimeout(t1); t1 = setTimeout(function () { // theSpan.find('a').removeClass("selected"); theMenu.stop().animate({ height: 0, opacity: 0 }, 200, function () { $(this).css({ display: "none" }); }); }, 250); } theSpan.hover(expand, collapse); theMenu.hover(expand, collapse); }); }
