如何从jQuery调用Controller方法

Question

我有以下ajax调用：

    $('#myModal').on('hidden.bs.modal', function () {
    $.ajax({
        url: '@Url.Action("UpdateCoverage", "Coverage")',
        type: 'GET',
        data: {},
        success: function (result, status, xhr) {
            alert("Result: " + status + " " + xhr.status + " " + xhr.statusText)
        },
        error: function (xhr, status, error) {
            alert("Result: " + status + " " + error + " " + xhr.status + " " + xhr.statusText)
        }
    });
})

...以及以下控制器方法：

 public ActionResult UpdateCoverage()
    //public async Task<ActionResult> UpdateCoverage(string searchTerm = null)
    {
    }

...我的控制器是

 public class CoverageController : BaseController

...

我收到了错误结果。我做错了什么？

编辑：网址只是/ Coverage / UpdateCoverage。其余的如何确定，在本例中为localhost：50891 /？ ajax调用是否必须进入View（cshtml）？

Answer 1

 var url='@(Url.Action("UpdateCoverage", "Coverage"))';
 $.get(url, function(data, status){
        alert("Data: " + data + "\nStatus: " + status);
  });
