How to convert string array in another array

Question

I have an ajax call which returns an array of strings and I need to convert this array into a javascript array : I explain with examples :

my return from ajax call is like that :

 success: function (doc) {
doc.d[0] // = "{ 'title': 'Espagne', 'start': '2016-05-24', 'end': '2016-05-25' }" 
doc.d[1] // = "{ 'title': 'Italie', 'start': '2016-05-18', 'end': '2016-05-20' }"
....

And I want to create a JavaScript Array like that :

 var countries = new Array();
 countries[0] = { 'title': 'Espagne', 'start': '2016-05-24', 'end': '2016-05-25' };
 countries[1] = { 'title': 'Italie', 'start': '2016-05-18', 'end': '2016-05-20' };

Have you an idea how to take the return string from doc.d and convert it to an array ?

If i do a thing like that :

var countries = new Array();
coutries[0] = doc.d[0] 

it can't work

It is possible to use .map() or .push() to build a new array using doc.d ?

• Nina Scholz: if you get a JSON conform string, you could use JSON.parse().
• Julien698: It works ! But i have to add in my case : JSON.parse('['+doc.d+']')

Answer 1

Just simply assign list to another variable

Try like this

var countries = JSON.parse(doc.d);

• Shrabanee: This way countries will have values as string, not in object format.

Answer 2

The JSON.parse() method parses a JSON string, constructing the JavaScript value or object described by the string.

JSON.parse(doc.d[0]);

Answer 3

Try following code

doc.d[0] = "{ 'title': 'Espagne', 'start': '2016-05-24', 'end': '2016-05-25' }" 
doc.d[1] = "{ 'title': 'Italie', 'start': '2016-05-18', 'end': '2016-05-20' }"
var arr = [];
if(doc.d.length)
{
 for(var i in doc.d)
 {
 arr.push(JSON.parse(doc.d[i]));
 }
 console.log(arr);
}

Else

doc.d[0] = "{ 'title': 'Espagne', 'start': '2016-05-24', 'end': '2016-05-25' }" 
doc.d[1] = "{ 'title': 'Italie', 'start': '2016-05-18', 'end': '2016-05-20' }"
var arr = [];
if(doc.d.length)
{
 for(var i in doc.d)
 {
 arr.push(doc.d[i].split('"')[1]); //This way also you can do
 }
 console.log(arr);
}

So arr[0] will be same as object of doc.d[0] and so on.
