ajax获取到的字符是类似下面的内容
复制代码 代码如下:
{a:"<divclass='pl_list'><div><spanclass='float_right'><ahref=javascript:goodbad(22835,26769,'good',1)title='支持一下'>支持：[0]</a><ahref=javascript:goodbad(22835,26769,'bad',1)title='我反对'>反对：[0]</a></span><spanclass='zz'>中国站长站网友：匿名于2008-04-25评论道：</span></div>谁认为投放了GoogleAdSense的站点就不允许进行推广了？傻子吧</div>",b:1}
然后用下面的ajax进行输出
复制代码 代码如下:
varkey='';
varstr=newArray();
functioncreateAjaxObj(){
varhttprequest=false
//document.domain='chinaz.com';

catch(e)

}
}
returnhttprequest;
