ASP.NET中防止页面多次提交的代码实现

1.   
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);
}
