ASP.NET中防止页面多次提交的代码实现

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(";
