来自chinaz的ajax获取评论代码

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
if(window.XMLHttpRequest){//ifMozilla,Safarietc
httprequest=newXMLHttpRequest()

try

}
catch(e)
{
try
{
httprequest=newActiveXObject(Microsoft.XMLHTTP);
}
catch(e){}
}
}
returnhttprequest;
}
