Parse JSON in JavaScript? [duplicate]
(16 answers)
Closed 6 years ago.
I have a string like :
$scope.text = '"{\"firstName\":\"John\",\"age\":454 }"';
and I want to convert to js object:
$scope.tmp = {"firstName":"John","age":454 };
Note: JSON.parse() doesn't work!!
It's my sample in codepen
You can do it with angular.fromJson()
in your sample, it would have been $scope.tmp = angular.fromJson($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.

I'm using typescript and I'm receiving a value with object format, but it's a string.
Lets call it as: myVar.
MyVar have this value (image below) as string.
const string myVar = '{"value":"1"}'
How can I transform this string to object for access your value?
you can use
JSON.parse('{"value": "1"}');
const myVar: string = '{"value":"1"}'
const myVarObj = JSON.parse(myVar)
console.log(myVarObj)

I'm attempting to run a list of strings through an object. When I do it individually it works, but when I pass it through as a string it doesn't work. How would I fix this?
// this doesn't work
var a = "IntegrationItem1";
var data = faq.a;
// but this works
var data = faq.IntegrationItem1;
What's causing the first example to not work? Is the variable data seeing it as faq."IntegrationItem1" instead of faq.IntegrationItem1?
You can access properties of the object using it's names:
var a = "IntegrationItem1";
var data = faq[a];
what you need is faq["IntegrationItem1"] => faq[a]

how do you get objects for events -> performances -> name & occurs_at to this json file https://api.myjson.com/bins/w05x using javascript. Cannot use regex since json API keeps changing format. Thanks
Use the JSON parser
obj = JSON.parse(json_string);
then you access it with
obj.events[event_index].performances[performance_index].performer.name
obj.events[event_index].name
obj.events[event_index].occurs_at
JSFiddle example of listing all the event attributes name and occurs_at.
