asp.net - 从另一个事件手动运行客户端验证代码

Question

我想运行任何客户端验证例程连接到特定的文本输入元素.

已使用CustomValidator以下方式设置验证:

<asp:textbox id="AddEstTime" runat="server" Width="55px"></asp:textbox><br />
<asp:CustomValidator ID="AddEstTimeCustomValidator" ClientValidationFunction="AddEstTimeCustomValidator_ClientValidate" OnServerValidate="AddEstTimeCustomValidator_ServerValidate" ErrorMessage="Please enter a time" ControlToValidate="AddEstTime"  runat="server" Display="Dynamic" ValidateEmptyText="true"/>
<asp:CheckBox ID="AddIsTM" runat="server" Text="T&amp;M" />

和javascript:

function AddEstTimeCustomValidator_ClientValidate(sender, args) {
    var checkbox = $("input[id$='IsTM']");
    args.IsValid = checkbox.is(":checked") || args.Value.match(/^\d+$/);
}

当CheckBox"AddIsTM"状态的变化,我想重新验证textbox"AddEstTime",利用其钩取CustomValidator"AddEstTimeCustomValidator".

在查看了 Microsoft 客户端代码后，我想出了这个似乎可行的方法：

// client-side validation of one user-control.
// pass in jquery object with the validation control
function ValidateOneElement(passedValidator) {
    if (typeof (Page_Validators) == "undefined") {
        return;
    }
    $.each(Page_Validators, function (index, value) {
        if ($(value).attr("id") == passedValidator.attr("id")) {
            ValidatorValidate(value, null, null);
        }
    });
}

这是在检查该Page_ClientValidate功能之后：

function Page_ClientValidate(validationGroup) {
    Page_InvalidControlToBeFocused = null;
    if (typeof(Page_Validators) == "undefined") {
        return true;
    }
    var i;
    for (i = 0; i < Page_Validators.length; i++) {
        ValidatorValidate(Page_Validators[i], validationGroup, null);
    }
    ValidatorUpdateIsValid();
    ValidationSummaryOnSubmit(validationGroup);
    Page_BlockSubmit = !Page_IsValid;
    return Page_IsValid;
}
