本文執行個體講述了AJAX簡單測試代碼。分享給大家供大家參考。具體如下：
用戶端：代碼如下：（AJAX_test.html ）
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><html xmlns="http://www.w3.org/1999/xhtml"><head><meta http-equiv="Content-Type" content="text/html; charset=utf-8" /><title>無標題文檔</title><script type="text/javascript"> var xmlhttp; //建立非同步對象 function initXmlHttp(){ if(window.ActiveXObject){ //IE瀏覽器 xmlhttp = new window.ActiveXObject("Microsoft.XMLHTTP"); } else if(window.XMLHttpRequest){ //非IE瀏覽器 xmlhttp = new window.XMLHttpRequest(); } } window.onload = initXmlHttp; //發送非同步請求 function sendRequest(){ //傳入一個 myname 參數 和 一個用於解決IE緩衝問題的即時毫秒數 xmlhttp.open("GET","AJAX_servers.aspx?myname=xg&" + new Date().getTime()); //指定當readyState屬性改變時的事件處理控制代碼onreadystatechange xmlhttp.onreadystatechange = funState; xmlhttp.send(null); } //擷取非同步結果 function funState(){ if( xmlhttp.readyState == 4) { if( xmlhttp.status == 200 || //status==200 表示成功！ xmlhttp.status == 0) //本機測試時，status可能為0。 { var re = xmlhttp.responseText; //alert(re); document.getElementById("divShow").innerHTML = re; } } }</script></head><body><button onclick="sendRequest();">發送</button><div id="divShow"></div></body></html>
伺服器端：代碼如下：（AJAX_servers.aspx ）
希望本文所述對大家的Ajax程式設計有所協助。
