参数未从视图正确传递给控制器​​操作

Question

对于我正在处理的应用，我为我正在处理的视图提供了以下Razor代码：

@Html.InputFor(m => m.Property1);   // A date
@Html.InputFor(m => m.Property2);   // Some other date
@Html.InputFor(m => m.SomeOtherProperty);  // Something else.
<a href='#' id='some-button'>Button Text Here</a>

<!-- SNIP: Extra code that dosen't matter -->

<script>
  var $someButton = $('#some-button');

  $(document).ready(function () {
    $someButton.click(function (e) {
      e.preventDefault();
      window.open('@Url.Action("Foo", "Home", new {p1 = Model.Property1, p2 = Model.Property2, pX = Model.SomeOtherProperty})', '_blank');
    });
  });
</script>

...评论时，我检查了呈现的HTML。正如预期的那样，值带有值......

<input name="Property1" data-val="true" data-val-required="(Required)" type="text" value="1/1/2013">
<input name="Property2" data-val="true" data-val-required="(Required)" type="text" value="4/11/2013">
<input name="SomeOtherProperty" data-val="true" data-val-required="(Required)" type="text" value="42">
<a href='#' id='some-button'>Button Text Here</a>

<script>
  var $someButton = $('#some-button');

  $(document).ready(function () {
    $someButton.click(function (e) {
      e.preventDefault();
      window.open('http://localhost:xxxx/Home/Foo?p1=1%2F1%2F2013&amp;p2=4%2F11%2F2013&amp;pX=42', '_blank');
    });
  });
</script>

......并在服务器端......

public ActionResult Foo(string p1, string p2, string pX)
{
  var workModel = new FooWorkModel
  {
    Property1 = p1,
    Property2 = p2,
    SomeOtherProperty = pX
  };

  // Do something with this model, dosen't really matter from here, though.
  return new FileContentResult(results, "application/some-mime-type");
}

我注意到只有第一个参数（p1）从前端获取值;我所有其他参数都传递空值！

问题：为这些其他字段分配了一些值时，为什么ActionResult会传递空值？或者，一个互补的问题：为什么只有第一个参数成功传递其值，而其他一切都失败了？

问题是由Url.Action()生成的转义网址引起的。 （来源：How do I pass correct Url.Action to a JQuery method without extra ampersand trouble?）

只需在@Html.Raw()周围添加Url.Action()来电，数据就会按预期流动。

 window.open('@Html.Raw(Url.Action("Foo", "Home", new {p1 = Model.Property1, p2 = Model.Property2, pX = Model.SomeOtherProperty}))', '_blank');
