protected void Page_Load(object sender, EventArgs e)
{
//.NET1.1
Button1.Attributes.Add("onclick", "this.disabled=true;" + this.GetPostBackEventReference(this.Button1));
//.NET 2.0以上
Button1.Attributes.Add("onclick", "this.disabled=true;" + this.ClientScript.GetPostBackEventReference(Button1, ""));
}
為了測試,我們可以建立一個頁面,加入一個btnAdd按鈕
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="AddAndEditUser.ASPx.cs" Inherits="AddUser" %><html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title>添加和編輯頁面示例</title>
</head>
<body>
<form id="frmMain" runat="server">
<ASP:Button ID="btnAdd" runat="server" CssClass="INPUT-BUTTON-Save" OnClick="btnAdd_Click">
</ASP:Button>
</form>
</body>
</html>

可見當點擊了按鈕,需要等5秒鐘按鈕才能點擊。即頁面回發一后按鈕才能用。這樣可以有效的防止用戶多次點擊按鈕,造成多次提交!
