Page_ClientValidate 正在验证多次. [英] Page_ClientValidate is validating multiple times.

问题描述

我遇到的问题是，验证摘要消息(警报)显示两次.我想不通原因.

problem i have is that, the validation summary message(alert) is displayed twice. I cannot figure out the reason.

请帮忙.这是代码

function validate() //javascript function
{
    if (typeof(Page_ClientValidate) == 'function') 
    {
        var isPageValid = Page_ClientValidate();
        if(isPageValid)
        {
        }
    }
}

<asp:Button ID="btn1" runat="server" OnClientClick="validate()" Text="button"
                    ValidationGroup="ContactGroup" />

<asp:ValidationSummary ID="ValidationSummary1" runat="server" DisplayMode="List" 
                    ShowMessageBox="true" ShowSummary="false" ValidationGroup="ContactGroup" />

推荐答案

问题是函数 Page_ClientValidate 接受一个输入参数，如果你不指定输入，则validationsummary 会针对每个 groupname 触发一次.

The problem is that the function Page_ClientValidate takes an input parameter, if you don't specify the input then the validationsummary triggers once per groupname.

在您的情况下，该函数触发两次:一次用于 groupname="ContactGroup"，另一次用于 groupname=""

In your case, the function triggers twice: once for groupname="ContactGroup" and another time for groupname=""

你应该改变

var isPageValid = Page_ClientValidate();

到

var isPageValid = Page_ClientValidate('');

如果您不想指定 ValidationGroup，或者如果您想指定组名，那么您需要像这样调用 Page_ClientValidate:

if you don't want to specify a ValidationGroup, or if you want to specify a groupname then you need to call Page_ClientValidate like so:

var isPageValid = Page_ClientValidate('ContactGroup');
