grid.getLocalRow（selectedIDs[i]）；var commodityCode=row.commodityCode；var commodityDesc=row.commodityDesc@VinothKrishnan:我写过，要访问

idsOfSelectedRows

，您应该1）在选项列表中添加

idsOfSelectedRows:[]

，2）在使用

idsOfSelectedRows

之前，将

idsOfSelectedRows=p.idsOfSelectedRows

包含到

和
loadComplete
回调中。您在注释中发布的代码在设置
idsOfSelectedRows
之前使用它（在
i=$.inArray（id，idsOfSelectedRows）
）。或者，您可以将
idsOfSelectedRows
的所有用法替换为
this.p.idsOfSelectedRows
@VinothKrishnan:请参见固定演示。我还更改了网格中的一些其他属性，包括
colModel
。
