在通过JQ Grid进行搜索时，不会调用Action类

我正在使用MVC 2.0 Web应用程序，其中有几个按钮，其onclick我称之为动作方法，但是当我第一次按下搜索按钮时，动作方法被调用但是之后如果我尝试单击搜索按钮，则动作方法是没有被召唤 .

另外，让我告诉您，我正在使用JQ Grid在按钮onclick上显示数据 . 请参阅下面的代码段 .

function LoadGrid（data，type）{

var showGrid = $("#showGrid");
        var navigation = $("#navigation");

        showGrid.jqGrid({
            url: '/Customer/CustomerSearchInfo',
            datatype: 'json',
            mtype: 'POST',
            cache: false,
            postData: { param: data, type: type },

            colNames: ['Customer Name', 'Contact Name', 'Company Number', 'Customer Number', 'Link Number', 'Phone', 'SalesRep Name', 'Sequence'],
            colModel: [
              { name: 'COMPANY_NAME', index: '1', align: 'left', sortable: true },
              { name: 'CONTACT_NAME', index: '2', align: 'left', sortable: true },
              { name: 'COMPANY_NUM', index: '3', align: 'left', sortable: true },
              { name: 'CUSTOMER_NUM', index: '4', align: 'left', sortable: true },
              { name: 'LINK_NUM', index: '5', align: 'left', sortable: true },
              { name: 'PHONE_1', index: '6', align: 'left', sortable: true },
              { name: 'SALESREP_NUM', index: '7', align: 'left', sortable: true },
              { name: 'ADDRESS_SEQ_NUM', index: '8', align: 'left', sortable: true }
             ],
            pager: navigation,
            rowNum: 10,
            rowList: [5, 10, 20, 30, 50],
            viewrecords: true,
            caption: '',
            height: '250px',
            sortorder: 'asc',
            sortname: '0',
            shrinkToFit: true,
            autowidth: true,
             }
        })

    };

提到的操作方法（/ Customer / CustomerSearchInfo）第二次没有被调用 .

[AcceptVerbs（HttpVerbs.Post）] public ActionResult CustomerSearchInfo（string param，int type）{

try
        {
            var custInfo = new List<Customer>();
            switch (type)
            {
                case 1:
                    custInfo = custDO.GetCustomerInfo(customerID: param);
                    break;
                case 2:
                    custInfo = custDO.GetCustomerInfo(customerName: param);
                    break;
                case 3:
                    custInfo = custDO.GetCustomerInfo(contactName: param);
                    break;
                case 4:
                    custInfo = custDO.GetCustomerInfo(companyID: param);
                    break;
                case 5:
                    custInfo = custDO.GetCustomerInfo(salesRepID: param);
                    break;
                case 6:
                    custInfo = custDO.GetCustomerInfo(phone: param);
                    break;
                case 7:
                    custInfo = custDO.GetCustomerInfo(addrtype: param);
                    break;
                case 8:
                    custInfo = custDO.GetCustomerInfo(status: param);
                    break;
                case 9:
                    custInfo = custDO.GetCustomerInfo(linkID: param);
                    break;
            }

                            return custInfo != null
                       ? Json(GetJson(custInfo, 10, custInfo.Count, 0),
                              JsonRequestBehavior.DenyGet)
                       : Json(null, JsonRequestBehavior.DenyGet);
        }
        catch (Exception ex)
        {
            Response.StatusCode = 500;
            return Json(null, JsonRequestBehavior.DenyGet);
        }


    }

以下是2个搜索按钮：

input id =“btnCustID”type =“button”class =“buttonsearch”title =“按客户ID搜索”onclick =“LoadGrid（document.getElementById（'txtCustID'） . value，1）”

input id =“btnCustName”type =“button”class =“buttonsearch”title =“按客户名称搜索”onclick =“LoadGrid（document.getElementById（'txtCustName'） . value，2）”
