利用Asp.net Ajax异步获取xml文档内容
Ajax原意本是让人利用异步获取XML内容,以实现无刷新的网页效果
asp.net ajax已将底层内容封装
实现起来远比自写xmlhttp来的方便,至少浏览器兼容方面要强得很多
下面以一个www.asp.net的示例说明一下利用microsoft ajax library来简单异步获取xml文档的方法
// 返回XML的Web 请求
function OnSucceededXml(executor, eventArgs)
{
if (executor.get_responseAvailable())
{
if (document.all)
resultElementId.innerText += executor.get_xml().xml;
else
// Firefox
resultElementId.textContent += "First node[首节点]: " +
executor.get_xml().documentElement.nodeName;

}
else
{
if (executor.get_timedOut())
alert("超时");
else
if (executor.get_aborted())
alert("失败");
}
}
function GetXml()
{
//创建WebRequest对象
wRequest = new Sys.Net.WebRequest();
![](http://images.csdn.net/syntaxhighlighting/OutliningIndicators/InBlock.gif)
//设置请求文件
wRequest.set_url("index.xml");
// Set the request handler.
wRequest.add_completed(OnSucceededXml);
// Clear the results area.
if (document.all)
resultElementId.innerText = "";
else
// Firefox
resultElementId.textContent = "";
// Invoke the Web request.
wRequest.invoke();
}
