通过ajax获取的数据，如何让其它js能执行？
通过ajax读取数据

 $(document).ready(function () {
//ajax读取数据并设置把相应的UL中的LI 某个ID上，

$.ajax({
            type: "get",
            dataType: "html",
            url: '/Ashx/act.ashx',
            data: sql,
 success: function (data) {
                $("#" + showul).html(data)
            },
});
});

================
需要执行的JS代码

$('li.caption').hover(function () {
            $(".cover", this).stop().animate({ top: '0px' }, { queue: false, duration: 160 });
        }, function () {
            $(".cover", this).stop().animate({ top: '-307px' }, { queue: false, duration: 160 });
        });

如果把数据直接写在页面上，上面这JS代码可以执行，但如果数据是通过ajax读取后再附加到页面上，而这块JS代码起不到作用，请教这要如何解决。谢谢。

引用:

$(document).on("hover","li.caption",function () {
            $(".cover", this).stop().animate({ top: '0px' }, { queue: false, duration: 160 });
        }, function () {
            $(".cover", this).stop().animate({ top: '-307px' }, { queue: false, duration: 160 });
        });

hover 改成 mouseover

jquery 的ajax把
<script scr='x'></script>封装好了。


// Install script dataType
jQuery.ajaxSetup({

if ( s.cache === undefined ) {
s.cache = false;
}
if ( s.crossDomain ) {
s.type = "GET";

// Bind script tag hack transport

if ( s.scriptCharset ) {

你可以试试这样
$('li.caption').live("hover",function () {
$(".cover", this).stop().animate({ top: '0px' }, { queue: false, duration: 160 });

}, function () {
$(".cover", this).stop().animate({ top: '-307px' }, { queue: false, duration: 160 });


或者你设置你的
$.ajax({
type: "get",
dataType: "html",
url: '/Ashx/act.ashx',
data: sql,
async:flase,//设置为同步请求，让这段ajax 执行完毕再在执行别的操作
success: function (data) {
$("#" + showul).html(data)
},
});
