MVC/Javascript:如何在表单提交中发布整数数组

在为MVC网页提交表单之前，我想查看控制器的关键字段列表。但是，控制器上的参数为null。我的JavaScript如下所示；

   $("#savePropertiesToBeAssigned").click(function (e) {
        e.preventDefault();
        var $propertyIds = $("#propertyRows").find($(".selectProperty:checked"));
        var propertyIds = [];
        $.each($propertyIds, function () {
            var propertyId = $(this).data("msurvey-property-id");
            propertyIds.push(propertyId);
        });
        var $form = $(this).closest("form")[0];
        $form.action += "?PropertyIds=" + propertyIds + "&page=" + GetHiddenField("msurvey-page");
        $form.submit();
    });

MVC操作是；

   [HttpPost]
    public async Task<ActionResult> AddFromContract(int[] PropertyIds, int? page)
    {
        var pageNumber = page.GetValueOrDefault(1);
        return RedirectToAction("AddFromContract", new { page = pageNumber });
    }

PropertyId错误地显示为null，而页面具有正确的值。编辑-我显示视图以回应评论：

@{
    ViewBag.Title = "Add properties from the contract into the survey";
}
@using (Html.BeginForm("AddFromContract", "PropertySurvey", FormMethod.Post))
{
    <div id="hiddenFields"
         data-msurvey-page="@ViewBag.Page"></div>
    <input type="hidden" id="propertyIds" name="propertyIds" />
    <fieldset>
        <legend>@ViewBag.Title</legend>
        @if (ViewBag.PagedList.Count > 0)
        {
            <section id="PropertyList" style="margin-right: 28px;">
                <p>
                    The properties below have already been added to the contract <b>@SessionObjectsMSurvey.SelectedContract.ContractTitle</b>, but are NOT in this survey
                    <b>@SessionObjectsMSurvey.SelectedContract.SurveyTitle.</b>
                </p>
                <table class="GridTbl">

                        </th>
