MVC4通过Ajax.BeginForm传递模型

我试图在这里关注一些good posts以使其工作,但每次我点击ajax回发时,我的控制器中的断点显示一个具有空值的模型。此页面显示仅供查看的模型值,但我已尝试将它们放在自己的表单中,并将它们包装在ajax表单中,似乎没有任何效果。

@model VendorProfileIntranet.Models.VendorProfile

$(function () {
$("form").submit(function () {
    if ($(this).valid()) {
        $.ajax({
            url: this.action,
            type: this.method,
            data: $(this).serialize(),
            success: function (result) {
                $("#message").html(result);
            }
        });
    }
    return false;
});

});

    @using (Ajax.BeginForm("SelectVendor", "Home", new AjaxOptions { HttpMethod="post", InsertionMode=InsertionMode.Replace, UpdateTargetId="message" }))
{
    <div style="float:right; width:500px">
        <div id="message"></div>
        <input id="btnSubmit" type="submit" value="Select Vendor" />
    </div>

此处缩写的视图非常长(仅显示要查看的模型值)。

<div id="viewform">
    <div id="viewform-contact" style="float:left;">
    <fieldset>
        <legend>Contact Information</legend>
        @Html.HiddenFor(model => model.ProfileID)
        <div class="view-field">
            @Html.LabelFor(model => model.Name)
            @Html.DisplayFor(model => model.Name)
        </div>
        <br />
        <div class="view-field">
            @Html.LabelFor(model => model.Email)
            @Html.DisplayFor(model => model.Email)
        </div>
        <br />
        <div class="view-field">
            @Html.LabelFor(model => model.Phone)
            @Html.DisplayFor(model => model.Phone)
        </div>
        <br />
        <div class="view-field">
            @Html.LabelFor(model => model.Website)
            @Html.DisplayFor(model => model.Website)
        </div>
        <br />
        <div class="view-field">
            @Html.LabelFor(model => model.CompanyName)
            @Html.DisplayFor(model => model.CompanyName)
        </div>
        <br />
        <div class="view-field">
            @Html.LabelFor(model => model.Address1)
            @Html.DisplayFor(model => model.Address1)
        </div>
        <br />
        <div class="view-field">
            @Html.LabelFor(model => model.Address2)&nbsp;
            @Html.DisplayFor(model => model.Address2)
        </div>
        <br />
        <div class="view-field">
            @Html.LabelFor(model => model.City)
            @Html.DisplayFor(model => model.City)
        </div>
        <br />
        <div class="view-field">
            @Html.LabelFor(model => model.State)
            @Html.DisplayFor(model => model.State)
        </div>
        <br />
        <div class="view-field">
            @Html.LabelFor(model => model.Zip)
            @Html.DisplayFor(model => model.Zip)
        </div>
        <br />
        <div class="view-fieldwide">
            @Html.LabelFor(model => model.VendorNotes)
        </div>
        <br />
        <div class="view-fieldwide">
            @Html.DisplayFor(model => model.VendorNotes)
        </div>
        <br /><br />
        </fieldset>
    </div>
}

控制器。我已经用一两种形式尝试了上述内容。使用上面的代码,模型包含除了隐藏在输入字段中的ProfileID之外的所有空值。我认为传递模型应该工作而不必为每个模型值创建一个隐藏字段?

[HttpPost]
        public ActionResult SelectVendor(VendorProfile pageModel)
    {
        // handle selected vendor
            _DAL.SelectVendor(pageModel.ProfileID);
            return Content("This Vendor has been selected", "text/html");
    }

ANSWER

由于使用DisplayFor

,模型值未绑定

答案 0 :(得分:7)

正如评论中所述,您实际上希望使用DisplayFor查看模型中放置在表单中的项目。 DisplayFor字段不会发布,它们只是用于显示。为了发回这些值,您需要为要发布的每个字段HiddenFor,以便模型绑定能够发挥作用。
