将键值对数组传递给.NET中的Controller操作

我有一个键值对,我通过它发送这样的值:

   $(document).on('click', '.chkAll', function () {
        $("#tableProducts thead tr th input:checkbox").change(function () {
            $(".chkItem").prop('checked', $(this).prop("checked"));
            if ($(this).prop('checked')) {
                $('tbody tr td input[type="checkbox"]').each(function () {
                    product_ids[$(this).attr('id')] = "Checked";
                    productLocation[$(this).attr('id')] = $(this).attr('location');
                });
            } else {
                $('tbody tr td input[type="checkbox"]').each(function () {
                    delete product_ids[$(this).attr('id')];
                    delete productLocation[$(this).attr('id')];
                });
            }
        });

这就是我将所有密钥发布到.NET MVC Action中的方法:

values: Object.keys(product_ids)

在Controller中获取它:

public ActionResult GetValues(List<string> values)
{
// now I have all the keys here but now I'd like values as well...
}

我想象这样做的方法是将整个名称 - 值对数组直接传递给函数,然后获取它,这样我就可以了:

// key (product id) => 0124914815DD29
// value => checked 

两个字符串......

我尝试过这样做:

values: product_ids // in jquery post

然后获取这样的值:

public ActionResult GetValues(Dictionary<string,string> values)
{
// but now the values dictionary is always empty
}

我该怎么做?

编辑:

这是发布数据的部分:

$(".btnAnalyze").click(function () {
            if (jQuery.isEmptyObject(product_ids) == true) {
                ShowMessage("You haven't selected any product!");
                return;
            }
            else {
                var guid = '@Guid.NewGuid()'
                var postData = { values: Object.keys(product_ids), drange: $('.range').val(), ID: guid, type: $('input[name=type]:checked').val(), shipping: $('input[name=shipping]:checked').val(), condition: $('input[name=condition]:checked').val(), minprice: $('.txtmin').val(), maxprice: $('.txtmax').val(), Title: $('.txtSearch').val(), negative: $('.txtNegativeKeywords').val(),locations: productLocation };
                $.ajax({
                    type: "POST",
                    url: "/Analyze/GetAllProducts",
                    data: postData,
                    success: function (data) {
                        if (data == "Error") {
                            alert("Something went wrong");
                        } else if (data=="Ok"){
                            window.location.href = '/Analyze/Index/' + guid // redirect to another page
                        }
                    },
                    dataType: "json",
                    traditional: true
                });
            }
        });

动作的映射标题:

  [HttpPost]
        public async Task<JsonResult> GetAllProducts(List<string> values, string drange, string ID, string type, string shipping, string condition, string minprice, string maxprice, string Title,string negative,string minFeedback, string maxFeedback, Dictionary<string,string> locations)

@Haim请看我传入函数的最后一个参数,那是我试图变成字典的那个......

答案 0 :(得分:1)

显然,在尝试绑定Dictionary时,默认模型绑定器需要以下格式:

locations[1]=val1&locations[2]=val2

但是使用jQuery的traditional parameterization代替你:

locations=[object+Object]
