我还有一个问题困扰我多天啊，不知道怎么解决，请问是否有高手可以帮助解决
还是一个Ajax程序，是这样的用Ajax获得TEXT的内容然后显示到页面上，TEXT中有分页的，然而失效了，我事先在别处用就好好的Ajax程序如下
function listPageComments(main_channel,second_channel,page,url){//其中page代表当前页面var data="main="+main_channel+"&second="+second_channel+"&page="+page;CreateAjax();xmlHttp.onreadystatechange=listPageCallBack;xmlHttp.open("POST",url+"?r="+new Date().getTime(),true);xmlHttp.setRequestHeader('Content-type','application/x-www-form-urlencoded');xmlHttp.send(data);return false;}function listPageCallBack(){if(xmlHttp.readyState==4){if(xmlHttp.status==200){document.getElementById("pinglun").innerHTML=xmlHttp.responseText;}}}PHP文件的程序如下cmmon_class.php
abstract class pages {
