I need help transforming the following JSON string into an array:
[{id: "1", type: "railroadCrossingSign", latitude: "55.647432", longtitude: "12.187673"}, {id: "2", type: "stationSign", latitude: "55.647444", longtitude: "12.187545"}]
When trying to use JSON.parse(), I encounter an error, likely due to the structure of the objects within the string...
Can anyone provide guidance on how to convert a JSON string containing objects into an array of objects?
JSON data needs to have keys wrapped in double quotes.
var str = '[{"id": "1", "type": "railroadCrossingSign", "latitude": "55.647432", "longitude": "12.187673"}, {"id": "2", "type": "stationSign", "latitude": "55.647444", "longitude": "12.187545"}]';
var arr = JSON.parse(str);
console.log(arr);To achieve your desired outcome, it is important that your JSON key value pairs are in string format as well.
For example:
var obj = '[{
"key" : "value"
}]';
When you execute the following code:
var obj = JSON.parse('{ "name":"John", "age":30, "city":"New York"}');
document.getElementById("demo").innerHTML = obj.name + ", " + obj.age;
You will receive the following output:
John, 30
