Ajax使用初步，配置步骤
1.把Ajax.dll copy到应用系统bin目录下，然后在工程引用中引用Ajax.dll，如果没有的话可以到网上下载
2.配置web.config，添加如下信息
<httpHandlers> <add verb="POST,GET" path="ajax/*.ashx" type="Ajax.PageHandlerFactory, Ajax" /></httpHandlers>4.在Pages\AjaxTest下建立cs文件AjaxForm.cs，添加如下方法
//[Ajax.AjaxMethod][Ajax.AjaxMethod(Ajax.HttpSessionStateRequirement.Read)]public static string GetNIVNumber(string str)
{
return str;
}<HTML> <HEAD> <title>AjaxForm</title> <meta name="GENERATOR" Content="Microsoft Visual Studio .NET 7.1"> <meta name="CODE_LANGUAGE" Content="C#"> <meta name="vs_defaultClientScript" content="JavaScript"> <meta name="vs_targetSchema" content="http://schemas.microsoft.com/intellisense/ie5"> <script language="javascript"> function testAjax(owner, item, evt)
{ var first=document.getElementById("txtfirst"); AjaxMethod.GetNIVNumber(first.value,callback_GetNIVNumber);
} function callback_GetNIVNumber(res) { var obj=document.getElementById("txtsecond"); obj.value=res.value; } </script> </HEAD> <body MS_POSITIONING="GridLayout"> <form id="Form1" method="post" runat="server"> <INPUT style="Z-INDEX: 101; LEFT: 208px; POSITION: absolute; TOP: 40px" type="button" value="Button" onclick="testAjax();"> <asp:TextBox id="txtfirst" style="Z-INDEX: 102; LEFT: 40px; POSITION: absolute; TOP: 40px" runat="server"></asp:TextBox> <asp:TextBox id="txtsecond" style="Z-INDEX: 103; LEFT: 40px; POSITION: absolute; TOP: 72px" runat="server"></asp:TextBox> </form> </body></HTML>protected System.Web.UI.WebControls.TextBox txtfirst;protected System.Web.UI.WebControls.TextBox txtsecond;private void Page_Load(object sender, System.EventArgs e){ //注册,其中Document.Pages.AjaxTest.AjaxMethod为AjaxMethod.cs方法所在的命名空间 Ajax.Utility.RegisterTypeForAjax(typeof(Document.Pages.AjaxTest.AjaxMethod));}
