使用JS传递数组型数据回服务器

//为数组添加一个方法，判断某个值是否存在于数组中
Array.prototype.in_array = function (e) {
for (i = 0; i < this.length && this[i] != e; i++);
return !(i == this.length);
}

var array = new Array();

//数组中的Item
var arr = {
//"RFQID": $("#ID").val(),
"RFQID": $(this).attr("rfqid"),
"SiteCode": $(this).attr("site"),
"ProcessID": $(this).attr("processid"),
"ForecastLoading": $(this).val(),
"SimulateNumber": 2,
"MainRFQID": $("#ID").val()
}

array .push(arr); //将Item塞入数组

$.ajax({
                    type: "Post",
                    processData: false,
                    contentType: 'application/json; charset=UTF-8',
                    url: "/ReportSimulation/UpdateProcessForecastLoading",
                    data: { list: arrObj },
                    beforeSend: function (xhr, setting) {
                        setting.data = JSON.stringify(setting.data);//转为Json
                    },
                    success: function (r) {
                        if (r.Success) {
                            alert("Success");
                        } else {
                            alert("Error");
                        }
                    }
                });

服务器接收：

public ActionResult UpdateProcessForecastLoading(List<ForecastProcessLoadingVM> list)

ForecastProcessLoadingVM 申明：

 public class ForecastProcessLoadingVM
    {
        public Guid RFQID { get; set; }
        public string SiteCode { get; set; }
        public Guid ProcessID { get; set; }
        public string ProcessName { get; set; }
        public double? ForecastLoading { get; set; }
        public int SimulateNumber { get; set; }
        public Guid MainRFQID { get; set; }
   }

JQGrid中，直接将grid getRowData就可以传回了：

　　　　　　var gridData = $gridCAPEX.getRowData();
            //var postData = JSON.stringify(gridData);
            //alert("JSON serialized jqGrid data:
" + postData);

            var data = {
                ID: $("#ID").val(),
                NeedNewCAPEX: $("#NeedNewCAPEX").val(),
                CAPEXVMList: gridData
            };


            $.ajax({
                type: "Post",
                processData: false,
                contentType: 'application/json; charset=UTF-8',
                url: "/BDFormPage/SaveCAPEX",
                data: data,
                beforeSend: function (xhr, setting) {
                    setting.data = JSON.stringify(setting.data);
                },
                success: function (r) {
                    if (r.Success) {
                        alert("Success");
                    } else {
                        alert("Error");
                    }
                }
            });

 注意：getRowData取的是innerHtml，针对Select类型的选项，一定要将其格式也设置为Select，否则会传回Text，不传回Value

{
                        label: "Category", name: "Category", index: "Category", hidden: false, editable: true,
                        editrules: { required: true },
                        edittype: "select", formatter: "select", editoptions: {
                            value: { 1: "New", 2: "Existing" }
                        }
                    },

加上

formatter: "select"，getRowData取出的是1 2，否则取出的是New Existing
