.Net环境下基于Ajax的MVC方案(2)
5、范例
包含在源码中的范例实现了一个简单的无刷新获取博客园首页内容到一个textarea的功能，详见源码！
部分范例源码：
Default.aspx
<%@ Page language="c#" Codebehind="Default.aspx.cs" AutoEventWireup="false" Inherits="CN.Teddy.AjaxHelper.WebForm1" %>

AjaxHelper.js摘要：
var AjaxHelperUrl = new String("Ajax.aspx");
var Updater = function(ajaxTemplate, output, params, onComplete)
{
if (typeof output == 'string')
{
output = $(output);
}
new Ajax.Request( 'Ajax.aspx', { onComplete: function(transport) { if (output != null) { output.innerHTML = FormatContent(transport.responseText); } if (onComplete != null) { onComplete(FormatContent(transport.responseText)) } }, parameters: params + '&AjaxTemplate=' + ajaxTemplate });
}
var SerializeForm = function(form)
{
return Form.serialize(form);
}
var FormatContent = function(str)
{
var content = new String(str);
var prefix = new String("<!--AjaxContent-->");
content = content.substring(content.indexOf(prefix, 0) + prefix.length, content.length - 9);
return content;
}
UserControl GetPageSrc.ascx.cs摘要：
private void Page_Load(object sender, System.EventArgs e)
{
lbUrl.Text = Request.Form["url"];
System.Net.WebClient client = new System.Net.WebClient ();
client.Headers.Add("User-Agent", "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; .NET CLR 1.1.4322)");
try
{
txtPageSource.Text = new System.IO.StreamReader(client.OpenRead(lbUrl.Text), System.Text.Encoding.UTF8).ReadToEnd();
}
catch(Exception ex)
{
throw ex;
}
