从这个JSON数组中，我需要在angularjs中构建带有手机号码的动态无线电按钮：
challengeSelectInfo:
[
{"mob_0" : "xxxxx1211"},
{"mob_1" : "xxxxx1211"},
{"mob_2" : "xxxxx1211"}
]
我尝试了ng-repeat并在challengeSelectInfo上进行迭代，但是我面临的问题是keys(mob_0,mob_1,mob_2)不同，我无法生成动态无线电按钮。
任何帮助将不胜感激。
谢谢
您需要为数组指定密钥：
$scope.newArr = [];
angular.forEach(challengeSelectInfo, function(val, key) {
/* do something for all key: value pairs */
$scope.newArr.push({id: key, value: val});
});
然后循环穿过newarr数组，并分配给广播按钮：
<input name="{{item.value}}" type="radio" ng-model="item.id" value="{{item.value}}">
仅出于您的理解目的而做到这一点，希望您可以使用此
来实现自己的要求
var app = angular.module('plunker', []);
app.controller('MainCtrl', function($scope) {
$scope.challengeSelectInfo= [
{"mob_0" : "xxxxx1211"},
{"mob_1" : "xxxxx1211"},
{"mob_2" : "xxxxx1211"} ];
});<!DOCTYPE html>

$scope.radioGrp = (data['challengeSelectInfo'] || []).map(function(obj){
for(var i in obj){
return { 'value': i, 'name': obj[i] };
}
});
<input type="radio" ng-repeat="rb in radioGrp" ng-value="rb.value" ng-modal="radioValue" name="{{rb.name}}">
