用.net 处理xmlHttp发送异步请求_ASP.NET技巧

var clickRouter=new jsEvent.EventRouter(iobj,"onclick");

clickRouter.addListener(btnTestGetClick);

}

function btnTestGetClick()

{ // open参数 url, onload, params, method, contentType, onerror

cobj = new net.xmlHttp("DefaultHandler.ashx?T=1",dealResult, null, "GET");

}

/**//* Get end*/

function dealResult()

{

var dobj = document.getElementById("divResult");

dobj.innerHTML = cobj.req.responseXML.text;

}

window.onload = function()

{

//绑定Post发送xmlHttp事件到btnTestPost

loadTestPost();

//绑定Get发送xmlHttp事件到btnTestGet

loadTestGet();

};

最后是.net处理xmlHttp的代码

.net 处理xmlHttp请求

public class DefaultHandler : IHttpHandler

{

protected XmlDocument _xmlResult;

public void ProcessRequest(HttpContext context)

{

if (context.Request["T"] != null)

{//GET xmlhttp测试

context.Response.ContentType = "text/xml";

XmlDocument xmlDoc = new XmlDocument();

xmlDoc.LoadXml(string.Format(@"<time>GET:{0}</time>", System.DateTime.Now));

xmlDoc.Save(context.Response.OutputStream);

context.Response.End();

}

else

{//POST xmlhttp测试

context.Response.ContentType = "text/xml";

XmlDocument xmlDoc = new XmlDocument();

xmlDoc.Load(context.Request.InputStream);

if (xmlDoc.DocumentElement.Name == "T")

{

xmlDoc.LoadXml(string.Format(@"<time>POST:{0}</time>", System.DateTime.Now));

xmlDoc.Save(context.Response.OutputStream);

context.Response.End();

}

}

}

public bool IsReusable

{

get

{

return false;

}

}

}
