此處提供的代碼用來實現當ASP.Net頁面中的某個Button被點擊後disable掉該頁面中所有的Button，從而防止提交延時導致的多次提交。基於之前的onceclickbutton腳本。
//ASP.Net中防止頁面多次提交的代碼: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中防止頁面多次提交的代碼: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);
//保證 __doPostBack(eventTarget, eventArgument) 正確注冊 if(!IsPostBack)
{
System.Text.StringBuilder sb = new System.Text.StringBuilder();
sb.Append(”if (typeof(Page_ClIEntValidate) == ‘function’)
{
if (Page_ClIEntValidate() == false)
{
return false;
}
}”); //保證驗證函數的執行 sb.Append(”if(window.confirm(’are you sure?’)==false) return false; “);
//自定義客戶端腳本 sb.Append(”disableOtherSubmit(); “);
// disable所有submit按鈕 sb.Append(this.GetPostBackEventReference(this.Button3));
//用__doPostBack來提交，保證按鈕的服務器端click事件執行 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!”);
}
}
此處只是disable掉所有的submit button, 我覺得其它的可提交控件也是可以通過類似的方法來disable的.
以上就是ASP.Net中防止頁面多次提交的代碼實現。
