前一陣發過一篇利用ExtJs的ScriptTagProxy實現Ajax跨域請求的文章(http://www.cnblogs.com/yjmyzz/archive/2008/09/14/1290789.html)，這幾天看了一下Jquery，發現如果用JQuery中的getScript其實更簡單(jquery 1.2.6版本)
這裡給出代碼，希望對Ajax跨域感到棘手的朋友有所協助:
代碼
<html>
<head>
<title>JQuery學習</title>
<script src="jquery-1.2.6.min.js" type="text/javascript"></script>
<script type="text/javascript">
$(document).ready(function(){
var oBtnTest = $("#btnTest");
oBtnTest.click(function(){
oBtnTest.disabled = true;
var oResult = $("#result");
oResult.html("loading").css("color","red");
jQuery.getScript("http://app.cntvs.com/test/js.txt",
function(){
oResult.html("name:" + jimmy.name + "<br/>email:" + jimmy.email).css("color","black");
oBtnTest.disabled = false;
});
});
});
</script>
</head>
<body>
<button id="btnTest">BtnTest</button>
<div id="result"></div>
</body>
</html>
遠程伺服器端js.txt的內容為:
var jimmy = {name:"jimmy.yang",email:jimmy.yang@163.com}
感覺是不是比ExtJs的ScriptTagProxy還要簡潔? 個人感覺Jquery簡單明了，短小精幹，ExtJs功能強大，組件豐富！
