如何在Angularjs中将字符串转换为对象
问题描述：
我有一个字符串：
$scope.text = '"{\"firstName\":\"John\",\"age\":454 }"';
我希望转换为js对象：
and I want to convert to js object:
$scope.tmp = {"firstName":"John","age":454 };
注意：
JSON.parse（）不起作用!!
这是 codepen
答
你可以用 angular.fromJson（）
在你的样本中，它应该是 $ scope.tmp = angular.fromJson（$ scope.text）;
in your sample, it would have been $scope.tmp = angular.fromJson($scope.text);
JSON.Parse（）和 angular.fromJson 之间的区别是，angular会检查到确保提供了一个字符串。如果它已经是一个对象，它将返回相同的对象。
The difference between JSON.Parse() and angular.fromJson, is that angular will check to make sure a string is provided. If it is already an object, it will return the same object.
