问题描述
我有这种一级树的情况:
json 在哪里:
问题是这会与他们的孩子一起创建 optgroups 但重复根源也是:
- GroupName1- 组名 2[组名1]- CHILDNAME1[组名2]
我想生产:
[ GroupName1 ]- CHILDNAME1[组名2] 解决方案
如果您将 json 更改为这样的内容，则分组不太像这样:
<预><代码>[{"ID":"1", "TIPIS":"GroupName1", "DESC":"name"},{"ID":"2", "TIPIS":"GroupName1", "DESC":"name1"},{"ID":"3", "TIPIS":"GroupName2", "DESC":"name2"},{"ID":"4", "TIPIS":"GroupName1", "DESC":"name3"},]然后你会得到你想要的分组

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>
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"}
]
the problem is that this creates the optgroups with their children but repeats
the roots too:
- GroupName1
- GroupName2
[ GroupName1 ]
- CHILDNAME1
[ GroupName2 ]
i want to produce:
[ GroupName1 ]
- CHILDNAME1
[ GroupName2 ]
解决方案
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"},
]
Then you'll get the grouping the way you want
