将按钮值从脚本发送到控制器

>假设有一个带有多个输入按钮的 .NET 引导窗体。 当用户按 Enter 键时，无论用户在哪个面板中修改数据，默认按钮值都会发送到控制器。 我认为代码确定哪个面板处于活动状态以及哪个按钮对应于该面板，但是如何将正确的面板的按钮值发送到控制器？ $closestButton.提交（）;没有工作，我在这里搜索问题找不到答案。 提前感谢！

控制器：

[HttpPost]
public ActionResult SaveData(SaveDataViewModel model, string buttonCommand)
{
    if (buttonCommand == "Save Basics")
    {
        //Do stuff
    }
    else if (buttonCommand == "Save Owner")
    {
        //Do other stuff
    }
    return View();
}

观点：

<div class="row">
    <div class="col-lg-12">
        <div class="panel panel-default" id="basicsPanel">
            <div class="panel-heading">Basic Info</div>
            <div class="panel-body">
                <div class="row">
                    <!-- Text boxes and such -->
                </div>
                <div class="row">
                    <!-- This is the default button upon pressing Enter key, and its value is always sent to the Controller -->
                    <button type="submit" id="saveBasics" name="buttonCommand" class="btn btn-success pull-right" value="Save Basics">Save Basics</button>
                </div>
            </div>
        </div>
    </div>
</div>
<div class="row">
    <div class="col-lg-12">
        <div class="panel panel-info" id="ownerPanel">
            <div class="panel-heading">Owner</div>
            <div class="panel-body">
                <div class="row">
                    <div class="col-lg-4">
                        <!-- Other text boxes and such -->
                    </div>
                </div>
                <div class="row">
                    <div class="col-lg-12 text-right">
                        <!-- This button should be the one used when a User presses the Enter key while filling in data in this panel -->
                        <button type="submit" id="saveOwner" name="buttonCommand" class="btn btn-success" value="Save Owner">Save Owner</button>
                    </div>
                </div>
            </div>
        </div>
    </div>
</div>

最后，检测按下了哪个按钮，但无法设置"buttonCommand"值的脚本：

$(document).keypress(function (e) {
    if (e.which == 13) {
        var $activeElement = document.activeElement.id;
        var $closestPanel = $($activeElement).closest('panel');
        var $closestButton = $($closestPanel).children('input[type=submit]');
        //Got the intended button, now how to send its value?
    }
});
