Jquery提交不张贴值到控制器

当我使用

 $("#FormEthernet").submit();

表单被张贴，动作在我的控制器中被击中，但是没有数据传递，所有输入都是空的。

(参数字典包含一个空条目…)

这是我的表格

 @using (Html.BeginForm("MyAction", "MyController",FormMethod.Post, new { id = "FormEthernet",name="FormEthernet" }))
{
  <div id="dialog-formEthernet" title="Update Ethernet Config">
    <p class="validateTips">
        All form fields are required.</p>
    <fieldset>
        <div>
            Phone Number</div>
        <div>
            <input type="text" name="TNEthernet" id="TNEthernet" />
        </div>
        <div>
            Up</div>
        <div>
            <input type="text" name="Up" id="Up" /></div>
        <div>
            Down</div>
        <div>
            <input type="text" name="Down" id="Down" /></div>
    </fieldset>
  </div>
}

任何想法?JQUERY错误?

更新这是我的控制器

    [HttpPost]
    public ActionResult MyAction(string TNEthernet,string Up, string Down)
    {
        return RedirectToAction("MyOtherAction", new { id = TNEthernet });
    }

And Some Fiddler (Sent)

下面是调用my submit的代码:

$("#dialog-formEthernet").dialog({
            autoOpen: false,
            height: 300,
            width: 350,
            modal: true,
            buttons: {
                "Set Configuration": function () {
                    var bValid = true;
                    allFields.removeClass("ui-state-error");
                    bValid = bValid && ensureTN(TNEthernet);
                    //up and down
                    bValid = bValid && checkRegexp(UP, /^'d+$/, "Upload");
                    bValid = bValid && checkRegexp(DOWN, /^'d+$/, "Download");
                    if (bValid) {
                        alert($("#Up").val()); //this works
                        $("#FormEthernet").submit();

                    }
                },
                Cancel: function () {
                    $(this).dialog("close");
                }
            },
            close: function () {
                allFields.val("").removeClass("ui-state-error");
            }
        });

我的HTML源代码

<form action="/MyController/MyAction" id="FormEthernet" method="post" name="FormEthernet"><div id="dialog-formEthernet" title="Update Ethernet Config">
    <p class="validateTips">
        All form fields are required.</p>
    <fieldset>
        <div>
            Phone Number</div>
        <div>
            <input type="text" name="TNEthernet" id="TNEthernet" />
        </div>
        <div>
            Up</div>
        <div>
            <input type="text" name="Up" id="Up" /></div>
        <div>
            Down</div>
        <div>
            <input type="text" name="Down" id="Down" /></div>
            <input id="FOO" name="FOO" type="text" value="FOO!" />
           <input type="submit" />
    </fieldset>
</div>
</form>
