问题描述
我有这种一级树情况:
I have this one level tree situation:
<select ng-model="tipost"
ng-options="tip.DESC group by tip.TIPIS for tip in tipall"><br>
</select>
json在哪里:
where the json is:
[
{"ID":"1", "IDPARENT":"0", "TIPIS":"", "DESC":"GroupName1"},
{"ID":"2", "IDPARENT":"1", "TIPIS":"GroupName1", "DESC":"CHILDNAME1"},
{"ID":"3", "IDPARENT":"0", "TIPIS":"", "DESC":"GroupName2"}
]
问题是,这会与他们的孩子一起创建optgroup,但会重复
根源也是如此:
the problem is that this creates the optgroups with their children but repeats
the roots too:
- GroupName1
- GroupName2
[ GroupName1 ]
- CHILDNAME1
[ GroupName2 ]
我想生产:
i want to produce:
[ GroupName1 ]
- CHILDNAME1
[ GroupName2 ]
推荐答案
如果将json更改为以下内容,分组将无法完全正常工作:
The grouping doesn't quite work like that, if you change your json to something like this:
[
{"ID":"1", "TIPIS":"GroupName1", "DESC":"name"},
{"ID":"2", "TIPIS":"GroupName1", "DESC":"name1"},
{"ID":"3", "TIPIS":"GroupName2", "DESC":"name2"},
{"ID":"4", "TIPIS":"GroupName1", "DESC":"name3"},
]
然后,您将按照想要的方式进行分组
Then you'll get the grouping the way you want
