Javascript jquery.valid（）=远程验证前为true

我在

MVC5

中工作，并结合使用客户端和服务器验证。对于这个特殊问题，我使用远程验证

Razorview：

<div id="studentStatus" name="studentStatus">
@using (Html.BeginForm("StudentStatus", "StudentStatus", FormMethod.Post, new { id = "studentStatusForm", data_timer = 240000 }))
{
    @Html.HiddenFor(x => x.CurrentStudentSepId, new { @class = "hideMe" })
    <div class="row">
        <h2 class="col-md-12 topSectionHeader">
            @StaffPortalResources.Section_StudentStatus
            <span class="savedStatus"></span>
        </h2>
    </div>
    <span class="errorNotification"></span>
    <div class="questionGroup form-group">
        <div class="row margin-btm-sm">
            <div class="col-md-4">
                @Html.LabelFor(x => x.StudentStatusId)
                @if (Model.IsReadOnly)
                {
                    <div>@Html.DisplayFor(x => x.StudentStatusId)</div>
                    @Html.HiddenFor(x => x.StudentStatusId)
                }
                else
                {
                    @Html.CustomComboBoxFor(x => x.StudentStatusId, (new { @class = "statusChangeValidationHandler", data_action = "GetStudentEditableStatuses", data_controller = "Lookup" }))
                }

                @Html.ValidationMessageFor(x => x.StudentStatusId)
            </div>
 }

控制员：

public JsonResult ValidateStudentStatus(StudentStatusSectionViewModel model)
{
    var errors = _studentStatusSectionAdapter.ValidateStudentStatus(model.CurrentStudentSepId, model.StudentStatusId);
    if (errors != null && errors.Any())
    {
        var currentStatus = _studentStatusSectionAdapter.Get(model.CurrentStudentSepId).StudentStatusId;
        Response.AddHeader("status", currentStatus);
        return Json(string.Join("</br>", errors), JsonRequestBehavior.AllowGet);
    }

    return Json(true, JsonRequestBehavior.AllowGet);
}

用于连接更改事件验证的jquery：

scope.initializeAutoSave = function (form, callBack) {
    var $form = $(form);
    $form.on("change", "input:not(.ignoreAutoSave)", queueForm);
    $form.on("change", "textarea:not(.ignoreAutoSave)", queueForm);
    window.Validation.initializeValidator($form);
    callBacks[$form.attr('id')] = callBack || function() {};
}

queueForm方法：

function queueForm(e) {
    if ($(e.target).valid()) {
        var $form = $(e.target).closest("form");
        var timer = $form.data("timer");
        autoSaveQueue[$form.attr("id")] = { $form: $form, timer: timer, attempt: 0 };
    }
}

在更改下拉列表中的值后跟踪代码时，change事件激发并调用queueForm函数。

valid（）

调用在远程验证发生之前计算为true

直到我跳过“if

（$（e.target）.valid（））

”行，它的计算结果为true并进入if块。然后跳入控制器中的远程

ValidateStudentStatus

功能

我做错什么了吗？我是否误解了远程验证的工作原理

如有任何见解或帮助，将不胜感激

scope.initializeAutoSave = function (form, callBack) {
    var $form = $(form);
    $form.on("change", "input:not(.ignoreAutoSave)", queueForm);
    $form.on("change", "textarea:not(.ignoreAutoSave)", queueForm);
    window.Validation.initializeValidator($form);
    callBacks[$form.attr('id')] = callBack || function() {};
}

function queueForm(e) {
    if ($(e.target).valid()) {
        var $form = $(e.target).closest("form");
        var timer = $form.data("timer");
        autoSaveQueue[$form.attr("id")] = { $form: $form, timer: timer, attempt: 0 };
    }
}
