复制代码 代码如下:

$(function(){
Ajaxload("?Uid=1<%= Yan.GET_Dict(id, 8, TableName)%>")
$("#ThreeM a:first").addClass("addBg");
$(".pageP2 a").live("click",function(){var NewUrl=$(this).attr("href");if(jQuery.browser.msie){var IE=$.browser.version;if(IE=="7.0" || IE=="6.0"){NewUrl="?" NewUrl.split('?')[1]}};Ajaxload(NewUrl);return false;});/*return false阻止默认a标签跳转,改用ajax请求*/
$("#ThreeM a").click(function(){
if(!$(this).hasClass("addBg")){$("#ThreeM a").removeClass("addBg");$(this).addClass("addBg")}
var Url="?Uid=1" $(this).attr("id");
Ajaxload(Url);
})
})
function Ajaxload(parm)
{
$.ajax({
type: "GET",
url: "/stus/3th.aspx" parm,
cache: false,
beforeSend:function(){$("#Three").html("
  load...
")},
success: function(msg){
$("#Three").html(msg);
},
error:function(){$("#Three").html("Load failure...")}
});
}

jQuery.browser方法有如下参数,返回true或者false: 
safari
opera
msie
mozilla 
是这里引用浏览器判断,是由于在IE6.0和7.0中a标签里的href="?Uid="获取过来是整个地址,不知道为什么。就用split截取了。。。

$.live()方法是1.3.2新增的的函数,在1.4.1可以支持自定义事件。具体查api吧。。。

另外关于live方法的冒泡:

ajax提交获取过来的动态生成的a标签,用Live()方法绑定了click事件。第二次查询时会执行2次click事件,冒泡了。用one()方法的话,点击一次就失效了。

最后用bind方法,在提交按钮cilick的时候,Unbind()取消绑定。就可以了。
