Ajax应用

mengyang

一. 正规的Ajax
var xmlHttp;var xmlHttp;function createXMLHttp(){if(window.ActiveXObject){xmlHttp = new ActiveXObject("Microsoft.XMLHTTP");}else if(window.XMLHttpRequest){xmlHttp = new XMLHttpRequest();}}function callBack(){if (xmlhttp.readyState == 4 && xmlhttp.status == 200){ var text = xmlhttp.responseText; //do...　} }function callHandler(){createXMLHttp();xmlhttp.onreadystatechange = callBack;var url = "";xmlHttp.open("get",url,true);xmlHttp.send();}

二. Prototype.js下的Ajax
function callHandler(){var url = '';var pars = '';var myAjax = new Ajax.Request(            url,            {method: 'get', parameters: pars, onComplete:callBack});}function callBack(originalRequest){var text=originalRequest.responseText;}
