导读：我有这个一级树状况： select ng-model="tipost" ng-options="tip.DESC group by tip.TIPIS for tip in tipall"br/select json在哪里 [ {"ID":"1","IDPARENT":"0","TIPIS":"","DESC":"GroupName1"},{"ID":"2","IDPARENT":"1","TIPIS":"GroupName1","DESC":"C

我有这个一级树状况：

<select ng-model="tipost" 
        ng-options="tip.DESC group by tip.TIPIS for tip in tipall"><br>
</select>

json在哪里

[
     {"ID":"1","IDPARENT":"0","TIPIS":"","DESC":"GroupName1"},{"ID":"2","IDPARENT":"1","TIPIS":"GroupName1","DESC":"CHILDNAME1"},{"ID":"3","DESC":"GroupName2"}
    ]

问题是这会创建与他们的孩子的optgroups但重复
根源：

- GroupName1
- GroupName2
[ GroupName1 ]
- CHILDNAME1
[ GroupName2 ]

我想生产：

[ GroupName1 ]
- CHILDNAME1
[ GroupName2 ]

提前致谢.

分组不会像这样工作,如果你将json更改为这样的事情：

[
 {"ID":"1","DESC":"name"},"DESC":"name1"},"TIPIS":"GroupName2","DESC":"name2"},{"ID":"4","DESC":"name3"},]

然后你会按照你想要的方式得到分组
