如何从JavaScript激活ASP.NET自定义验证器？

Question

我想在javascript中编写一个函数,每当我在webform中调用它时,它会在同一个webform中激活一个特定的验证器.

Answer 1

<asp:RequiredFieldValidator ID="passwordRequiredFieldValidator" runat="server" 
    ErrorMessage="* Password Required!"
    EnableClientScript="true" CssClass="errorText" 
    ControlToValidate="passwordTextBox"> 
</asp:RequiredFieldValidator>

要激活此验证器,请使用:

window.ValidatorValidate(window.passwordRequiredFieldValidator);

进一步举例:

function ValidatePassword() {
    window.ValidatorValidate(window.passwordRequiredFieldValidator);
    var valid = window.passwordRequiredFieldValidator.isvalid;
    alert(valid);
}

Answer 2

if (Page_ClientValidate('Validation Group'))
{
    //Your valid
}
