ASP.NET中防止页面多次提交的代码实现

2010-07-15 13:38 661 查看
此处提供的代码用来实现当asp.net页面中的某个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.

以上
就是ASP.NET中防止页面多次提交的代码实现。
