Question

我正在使用MVC4和VS2012

要求： 想要通过局部视图显示网格数据＆amp;从方法加载数据。

问题： 我成功地将数据从方法加载到局部视图但没有参数。

index.cshtml

中的

<div id="gridContent"></div>

<script src="~/Content/SB/js/json2.js"></script>

<script>
    $(document).ready(function () {
        $("#btnGo").click(function () {             
            loadGrid();
        });          
    });
</script>

 <script>
     function loadGrid() {
         var booksDiv = $("#gridContent");
         var items = {};
         items.vFinYear = $("#ddl_FinnYear").val();
         items.vDeptCode = $("#ddl_Dept").val();

         $.ajax({
             cache: false,
             type: "GET",
             url: "/Voucher/VoucherRaisedbyMePartial" ,
             data: '{items: ' + items + '}',
             success: function (data) {
                 booksDiv.html('');
                 booksDiv.html(data);
             },
             error: function (xhr, ajaxOptions, thrownError) {
                 debugger;
                 alert(thrownError);
                 alert('Failed to retrieve data.');
             }
         });
     }
</script>

in凭证控制器

    public ActionResult VoucherRaisedbyMePartial(Voucher items)
    {
        // Problem is here: Unable to get values in parameter items
        // Data loading in partial view sucessfully, but i want to filter
        // data on the basis of departmet and financial year.

        var VoucherList = new List<Voucher>();          
        return PartialView("_VoucherRaisedbyMePartial", VoucherList);
    }

Answer 1

使用HttpPost属性

将操作更改为发布

[HttpPost]
public ActionResult VoucherRaisedbyMePartial(Voucher items)

在你的ajax调用中你可以像这样直接传递json对象

 $.ajax({
     cache: false,
     type: "POST",
     url: "/Voucher/VoucherRaisedbyMePartial" ,
     data: { items: items },
     success: function (data) {
         booksDiv.html('');
         booksDiv.html(data);
     },
     error: function (xhr, ajaxOptions, thrownError) {
         debugger;
         alert(thrownError);
         alert('Failed to retrieve data.');
     }
 });

Answer 2

更改是post，内容类型是application / json;字符集= UTF-8

  $.ajax({
             cache: false,
             type: "POST",
             contentType: "application/json; charset=utf-8",
             url: "/Voucher/VoucherRaisedbyMePartial",
             data: '{items: ' + JSON.stringify(items) + '}',

             success: function (data) {
                 booksDiv.html('');
                 booksDiv.html(data);
             },
             error: function (xhr, ajaxOptions, thrownError) {
                 debugger;
                 alert(thrownError);
                 alert('Failed to retrieve data.');
             }
         });
