客户端自定义的验证 [英] client side custom validator

问题描述

我试图做客户端自定义验证。我在我的aspx页面下面的code，但我不断收到一个错误说

I am trying to do client side custom validation. I have the following code in my aspx page, but I keep getting an error saying

System.Web.HttpException（0X80004005）：控制chkList_Counts
  通过validationCheck的ControlToValidate属性引用
  无法验证。在
  System.Web.UI.WebControls.BaseValidator.CheckControlValidationProperty（字符串
  名，弦乐propertyName的）在
  System.Web.UI.WebControls.CustomValidator.ControlPropertiesValid（）在
  System.Web.UI.WebControls.BaseValidator.On preRender（EventArgs e）上
  在

System.Web.HttpException (0x80004005): Control 'chkList_Counts' referenced by the ControlToValidate property of 'validationCheck' cannot be validated. at System.Web.UI.WebControls.BaseValidator.CheckControlValidationProperty(String name, String propertyName) at System.Web.UI.WebControls.CustomValidator.ControlPropertiesValid() at System.Web.UI.WebControls.BaseValidator.OnPreRender(EventArgs e) at System.Web.UI.Control.PreRenderRecursiveInternal() at

我甚至不能看到我的网页。我得到的错误就在在显示页面之前。

I cannot even see my page. I get the error right away before the page displays.

下面是我的code

   <div> 
          <asp:Panel ID="panel3" runat="server" CssClass="cis_edit_pnl" 
              GroupingText="Counts" Width="1240px"> 
              <asp:CheckBoxList ID="chkList_Counts" runat="server" 
                   RepeatDirection="Horizontal" 
                   RepeatColumns="3" Width="1060px"> 
              </asp:CheckBoxList> 
               <asp:CustomValidator ID="validationCheck" runat="server" ControlToValidate="chkList_Counts" ClientValidationFunction="check_checkBoxList" EnableClientScript="true" ErrorMessage="At least one of the check boxes should be checked"> 
                </asp:CustomValidator> 
         </asp:Panel> 
  </div>

和我的javascript函数是这样的。

and my javascript function is like this

    function check_checkBoxList(sender, args) { 
        debugger; 
        if (check_Counts() == false) { 
            args.IsValid = false; 
            return; 
        } 
        args.IsValid = true; 
        return; 
    } 

 function check_casrepCounts() { 
        var control; 
        control = document.getElementById("<%=chkList_Counts.ClientID %>").getElementsByTagName("input"); 
        if (eval(control)) { 

            for (var i = 0; i < control.length; i++) { 
                if (control[i].checked == true) 
                    return true; 
            } 
            return false; 
        } 
    }

先谢谢了。

推荐答案

它正常工作，现在，我不得不删除的ControlToValidate和它的工作。

It works fine now, I just had to remove controlToValidate and it worked.
