思路：基于onceclickbutton脚本。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。
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。 |
