jqgrid no url reset

如果发现 jqgrid 在运行中出现次错误，可能是以下原因

 $('#@(ViewBag.tabcid + "_grid")').jqGrid('navGrid', '#@(ViewBag.tabcid + "_page")',
       {//options
           view: false,
           del: ('@ViewBag.type' != null && '@ViewBag.type' == "1") == true,
           add: false,
           edit: false,
           search: false,
           refresh: true
       },
       {//edit options 
          
       },
       { // add options 
         
       },
       {//del options 
           reloadAfterSubmit: true, closeOnEscape: true//
           , url: '@Url.Action("Delete")'
           , beforeShowForm: function (form) {
           }
           , afterComplete: function () {
               //jQuery("#shipFactorList_d").jqGrid('clearGridData', true);
               //jQuery("#shipFactorList_d2").jqGrid('clearGridData', true);
           }
           , afterSubmit: function (response, formid) {
               var data = JSON.parse(response.responseText);
               if (data.status) {
                   return [true, "OK", data.id];
               }
               else {
                   return [false, data.errmsg];
               }
           }
       },
       {  },// search options 
       {  } //view options 

   );

 以上可以看到  options 中定义的按钮 应该 对应到每一个大括号
