Javascript 如何在Angularjs中将字符串转换为对象

How to convert string to object in Angularjs

提问by Ehsan Ali

I have a string like :

我有一个像这样的字符串：

$scope.text = '"{\"firstName\":\"John\",\"age\":454 }"';

and I want to convert to js object:

我想转换为 js 对象：

 $scope.tmp =  {"firstName":"John","age":454 };

Note: JSON.parse()doesn't work!!

It's my sample in codepen

注意：JSON.parse()不起作用！！

这是我在codepen 中的示例

You can do it with angular.fromJson()

你可以用angular.fromJson()

in your sample, it would have been $scope.tmp = angular.fromJson($scope.text);

在你的样本中，它本来是 $scope.tmp = angular.fromJson($scope.text);

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.

JSON.Parse()和angular.fromJson,之间的区别在于angular 将检查以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。
