求php+ajax 分页实例

ajax.js代码:

var http_request=false;
function send_request(url)
{
http_request=false;
//开始初始化XMLHttp对象
if(window.XMLHttpRequest){//MOILLA浏览器

http_request=new XMLHttpRequest();
if(http_request.overrideMimeType){
http_request.overrideMimeType("text/xml");

}

}
else if(window.ActiveXObject){//IE 浏览器
try{
http_request=new ActiveXObject("Msxml2.XMLHttp");
}catch(e){
try{
http_request=new ActiveXObject("Microsoft.XMLHttp");
}catch(e){}

}

}if(!http_request){
window.alert("创建XMLHttp对象失败");
return false;

}
http_request.onreadystatechange=processrequest;
//确定发送请求方式，URL，及是否同步执行下段代码
http_request.open("GET",url,true);
http_request.send(null);

}
