发布操作无效，需要帮助，将信息从视图传递到控制器

Question

Given the following form in the Index view, which includes two hidden inputs and one input that is a slider: (The hidden imputs have their values updated by a geolocation function executed on loading the page which includes:

document.getElementById("startLatitude").value = lattitude; 
document.getElementById("startLongitude").value = longitude;

where the lattitude and longitude variables have been set by the geolocation call. Also the value of the slider is updated as it is moved.)

<form name="ourform" action="Index" method="POST">
  <fieldset>
    <ul style="list-style-type:none">
      <li>
        <input type="hidden" name="startLatitude" id="startLatitude" value="" />
        <input type="hidden" name="startLongitude" id="startLongitude" value="" />10
        <input type="range" id="timeInput" min="10" max="60" value="15" step="1" onchange="showValue(this.value)" />60
      </li>
      <li>
        <br />
      </li>
      <li>
        <input type="submit" name="button" value="Let's Go!" onClick="submit" />
      </li>
    </ul>
  </fieldset>
</form>

and also an overloaded home controller method intended to receive the POST:

[HttpPost]
public ActionResult Index(string timeInput, string startLatitude, string startLongitude)
{
  ...
}

Currently the POST action does not append the parameters to the URL when the form is submitted. Why not? What can be done to make sure they do? (What should be in the form attribute ACTION?) Alternatively, is there a better method to ensure the information is passed into the controller?

将此行修复为：

<form name="ourform" action="@Url.Action("Index")" method="POST">
