AngularJS JSON foreach值问题
我目前正在开发AngularJS / Parse.com网络应用程序
我想要实现的目标：
我想展示每个问题_4_p1＆＃39;来自Parse.com JSON数据的值。
当前问题：
我已设法使用foreach函数显示每个问题_4_p1＆＃39;值，但由于某种原因，它将每个值拆分为多个值 - 逐个字母。
任何帮助/建议都会有所帮助！
HTML：
<md-card>
<md-card-content ng-controller="parseData">
{{parseRecommendations | json}}
</md-card-content>
</md-card>
控制器JS：
dashApp.controller("parseData", function ($scope, $http) {
$scope.parseRecommendations = [];
$http({
method : 'GET',url : 'https://api.parse.com/1/classes/Customers',
headers: { 'X-Parse-Application-Id':'xxx', 'X-Parse-REST-API-Key':'xxx'}
})
.success(function(data, error) {
$scope.parseResults = data.results;
angular.forEach($scope.parseResults, function(results) {
angular.forEach(results.question_4_p1, function(value) {
$scope.parseRecommendations.push(value);
});
});
})
.error(function(data, error) {alert('Failed, error code: ' + error.message);
});
});
JSON数据：

1 个答案:
答案 0 :(得分：0)
您没有正确循环。
$scope.parseResults = data.results; // your results array
// for each result...
angular.forEach($scope.parseResults, function(results) {
// loop over the question value?
angular.forEach(results.question_4_p1, function(value) {
$scope.parseRecommendations.push(value);
});
});
});
您在第一次迭代时循环$scope.parseResults[0].question_4_p1，而您正在循环的值是“是”＆＃39;。
当你循环一个字符串时，你会循环遍历它的字符。
对于每一行，你都会在同一个问题上循环，所以你最终得到的是“是的，是的，是的，还有是等等。”
你需要失去内循环，你会得到你想要的东西：
$scope.parseResults = data.results; // your results array
angular.forEach($scope.parseResults, function(results) {
$scope.parseRecommendations.push(results.question_4_p1);
});
});
这会留给您['yes', 'no', 'yes', 'yes', 'yes']等。
