Question

How do I send back an array of values back to a controller action via $.get?

I have tried (string[] values) and (List).

     ...
     var val = $('#CStatus').val();  // Get a list of selected values
     alert(val);   // Displays 0,1
            $.get('@Url.Action("GO")', {  junk: val }, function (data) {
                $('#gridview').html(data);
            });


    public ActionResult GO(List<String> junk /* or string[] junk or string junk*/)
    {
        // junk is null!
    }

Answer 1

The following was even failing

  $.post('@Url.Action("GO")', { 'values': [1,2,3]}, function (data) {
      ...
  });

But this fixed it:

jQuery.ajaxSettings.traditional = true;

Here is a good article describing the issue.

With the following Controller ActionResult Sig:

[HttpPost]
public ActionResult GO(string[] values)
{
    // junk is no longer null!
}
