如何在jqgrid中设置checkbox多选，及获取多选的值（学习笔记）

//JS

//canv_init_gridb(grid_url, _colnames, _colmodel,'rd_time','desc');


$(grid_selector).jqGrid(
{
url : grid_url,
datatype : "json",
mtype : 'POST',
shrinkToFit : true,// 适用于较少字段,响应式
colNames : _colnames,
colModel : _colmodel,
jsonReader : {
id : "id"
},
　multiselect: true,//可多选
 onSelectRow: function (rowId, status, e) {  
 var rowIds = jQuery("#grid-table").jqGrid('getGridParam', 'selarrrow');    //获取勾选记录的ID
         /***********勾选导出*************/
       $('#btn-out').on('click', function() {
           parent.location.href = '${ctx}/admin/rcd/export?filter='+'filter__id='+rowIds;
           layer_chose();
           return false;
       });
       /*********导出*********end*******/
 },
pager : "#grid-pager",
rowNum : 25, //每页显示记录数 
viewrecords : true, //是否显示行数 
rowList : [ 25, 50, 100, 200, 500 ], //可调整每页显示的记录数 
postData : {
filter : 'filter__ct_mobile=-1',
sort : 'rd_time',
order : 'desc'
}
});

重点：multiselect: true,//可多选
  onSelectRow: function (rowId, status, e) {  

 var rowIds = jQuery("#grid-table").jqGrid('getGridParam', 'selarrrow');    //获取勾选记录的ID
