EasyUI 中的双击某行 并赋值给input事件

项目是由mvc+easyUI开发，双击事件在下边.有注释写着呢

function DataList(supCode) {
        myDatagrid2.datagridId = "GridViewTable";
        myDatagrid2.title = "";
        myDatagrid2.title = "供应商信息";
        myDatagrid2.pagination = false;
        myDatagrid2.datagridiconcls = "icon-tip";
        myDatagrid2.dataUrl = "/Supplier/GetTempList/?supCode=" + supCode;
        myDatagrid2.pageList = [10, 50, 100];
        myDatagrid.pagesize = 10;
        myDatagrid2.height = 130;
        myDatagrid2.fit = false;
        //myDatagrid2.fitColumns = true;//列自适应
        myDatagrid2.idFiled = 'SupCCode'; //主键列的列明
        // myDatagrid2.toolbar = "#toolbar";
        myDatagrid2.columns = [
            { field: 'SupName', title: '供应商名称', sortable: true, align: 'center' },
            { field: 'SupCCode', title: '供应商联系人ID', sortable: true, align: 'center', hidden: 'true' },
            { field: 'SupCContact1', title: '联系人',sortable: true, align: 'center' },

            { field: 'SupCAddress', title: '地址', sortable: true, align: 'center' }
        ];
        myDatagrid2.init();
        // myDatagrid2.initToolbar();
        //双击事件
        $("#GridViewTable").datagrid({
