Question

从这个json数组我需要在angularjs中构建带有移动号码的动态单选按钮：

challengeSelectInfo:
[
    {"mob_0" : "xxxxx1211"},
    {"mob_1" : "xxxxx1211"},
    {"mob_2" : "xxxxx1211"}
]

我尝试ng-repeat并迭代challengeSelectInfo，但我遇到的问题是keys(mob_0,mob_1,mob_2)不同，我无法生成动态单选按钮。

感谢任何帮助。

您需要为数组指定键：

$scope.newArr = [];
angular.forEach(challengeSelectInfo, function(val, key) {
    /* do something for all key: value pairs */
     $scope.newArr.push({id: key, value: val});
});

然后遍历newArr数组并分配给单选按钮：

<input name="{{item.value}}" type="radio" ng-model="item.id" value="{{item.value}}">
