javascript - 使用javascript为html链接中的id赋值

Question

我有以下链接，该链接将 id 传递到我的 Controller 以呈现报告。

<a href="@Url.Action("GetReport", new { type = "PDF", id = 12345})" class="btn btn-default btn-primary">Print Report</a>

我想将上面链接中的这个值 id 分配给我在下面的调用中从数据库返回的结果....

// Global variable
var DocumentID = null;

$('#Save').click(function(e) {

     if (document.forms[0].checkValidity()) {

         e.preventDefault();

         $.ajax({
             url: "/Home/SaveDetails",
             dataType: "json",
             type: "POST",
             data: ko.toJSON(viewModel),
             contentType: "application/json;charset=utf-8",
             success: function(result) {
             if (result > 0) {
                 //Assign return value to DocumentID
                 DocumentID = result;
                 alert("This work request has been successfully saved in database. The Document ID is: " + result);
              } else {
                alert("The Work Request was not saved, there was an issue.");
              }
          },
          complete: function() {
              // Hide loading image.
          },
          error: function(jqXHR, textStatus, errorThrown) {
              // Handle error.
              alert(errorThrown);
          }
      });
    } else {
        alert("Form is not valid");
    }
});

上面的调用有效并返回一个 DocumentID 并成功显示在警报中。如果 id 具有硬编码值，则上面的链接有效；我只想让这个值动态化。

if (result > 0) {
   //Assign return value to DocumentID
   var DocumentID = result;
   var href = '@Url.Action("GetReport", new { type = "PDF", id =' + DocumentID +'})';  
   $("a:contain('Print Report')").attr('href', href);               
}
