我现在需要绑定后台获取的数据到select上
后台返回的JSON:
js部分:
然后,读取用户的选择数据,把用户的数据显示到select上,选中状态
但是怎么都绑定不了,一看控制台:
value上全部出现了number:1
这样的格式,OK!那我加上track by x.nation_id
number是没有了,但是数据又绑定不了了!
比如:用户选择的是苗族,那么nation_id是6,按道理
$scope.originOptions = {'nation_id':6}
可以绑定上啊!但是就是不行!是我哪里出错了吗
请问大家怎么回事啊!!
我刚又实验了下:加了track by就绑定不上,去掉就可以!
但是又不要value里的字符类型,怎么破~~
ng-model="originOptions"
No problem~ That’s it. What you get in the controller is the id value
$scope.originOptions.nation_id
You can read this article
controller:
HTML:
Try this data structure
The character type in value cannot be obtained through the bound ng-model.
Although it shows number:1
ngOptions is generated like this
You can take a look at the documentation for examples:
