ASP.NET中防止页面多次提交的代码实现

Button被点击后disable掉该页面中所有的Button，从而防止提交延时导致的多次提交。基于之前的onceclickbutton脚本.

//ASP.NET中防止页面多次提交的代码:javascript

< script language="javascript">

< !--

function disableOtherSubmit() { 

var obj = event.srcElement;
var objs = document.getElementsByTagName('INPUT');
for(var i=0; i< objs.length; i++)
{
if(objs[i].type.toLowerCase() == 'submit')
{
objs[i].disabled = true;
}
}
}

//--></script>

//ASP.NET中防止页面多次提交的代码:

asp.netpublic class PreventMultiClick : System.Web.UI.Page { 

protected System.Web.UI.WebControls.Button Button1;

protected System.Web.UI.WebControls.Button Button2;
protected System.Web.UI.WebControls.LinkButton LinkButton1;

protected System.Web.UI.WebControls.Button Button3;

private void Page_Load(object sender, System.EventArgs e)
{
　　this.GetPostBackEventReference(this.Button3);
//保证 __doPostBack(eventTarget, eventArgument) 正确注册

if(!IsPostBack)
{
System.Text.StringBuilder sb = new System.Text.StringBuilder();
sb.Append("if (typeof(Page_ClientValidate) == 'function')
{
　　if (Page_ClientValidate() == false)
{
return false;
}
}");

//保证验证函数的执行

sb.Append("if(window.confirm('are you sure?')==false) return false; ");
//自定义客户端脚本

sb.Append("disableOtherSubmit(); ");
// disable所有submit按钮

sb.Append(this.GetPostBackEventReference(this.Button3));
//用__doPostBack来提交，保证按钮的服务器端click事件执行

sb.Append("; ");
Button3.Attributes.Add("onclick",sb.ToString());
}
}

#region Web Form Designer generated code override

protected void OnInit(EventArgs e)
{
// // CODEGEN: This call is required by the ASP.NET Web Form Designer. //

InitializeComponent();
base.OnInit(e);
}
/// < summary>

/// Required method for Designer support - do not modify

/// the contents of this method with the code editor.

/// < /summary>

private void InitializeComponent()
{
this.Button3.Click += new System.EventHandler(this.Button3_Click);

this.Load += new System.EventHandler(this.Page_Load);
}
#endregion

private void Button3_Click(object sender, System.EventArgs e)
{
System.Threading.Thread.Sleep(3000);
Response.Write("Hello world!");
}
}

此处只是disable掉所有的submit button, 我觉得其它的可提交控件也是可以通过类似的方法来disable的.
