easyui datagrid 查看是否存在某条记录

var dg = '#goods-dg';
var index = $(dg).datagrid('getRowIndex', goods.row.sortid);
if (index > -1) {//这里显示错在
$('#goods-dg').datagrid('selectRow', index);//存在就直接选择
return false;//结束返回
}

重点,要在参数里添加:idField:'sortid'.这里是根据sortid,一般情况下为id

完整代码如下

,dginit: function () {
goods.index = -1;
var dg = '#goods-dg';
$(dg).datagrid({
idField: 'sortid'
, rownumbers: true
, singleSelect: true

goods.total();
