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

        controller:

        $scope.data = { model: null, nation: [ {nation_id: '1', name: 'A'}, ....... ....... ] };

        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:
