魏言AJAX 类
使用方法:
<mce:script type="text/javascript"><!--
var classAjax = new Ajax(sUrl,sRecvTyp,sQueryString,oResultFunc);
classAjax.post();//post方式发送数据
classAjax.get();//get方式发送数据
//sUrl发送地址
//sRecvTyp 接受数据类型:0为xml 1为text
//oResultFunc 返回结果处理函数
// --></mce:script>
应用实例：
<mce:script type="text/javascript"><!--
var ajax1 = new Ajax("1.asp",0,"id="+id,bacal);
ajax1.post();
function bacal(rexm){
//返回数据处理函数;
}
// --></mce:script>

上面一篇博文<<Ajax访问Xml Web Service的安全问题以及解决方案>>中谈及xml web service与wcf新老架构对于ajax安全性的问题,得出了结论,但没有具体验证,本文正是为了验证上文中关于新架构MEX结点与业务终结点分离更有利于服务安全的结论,并稍带着讲述如何在vs2008中用ajax与wcf进行交互.
第一步: 在vs2008中 ......
