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。
