But when i try to get for example 'couleurCat', i have undefined. I have try like this :

data['couleurCat']
data.couleurCat

but always undefined

Answer 1

You need to restructure your string as JSON before you can access elements. To access the JSON object in JavaScript, parse it with JSON.parse() , and access it via . or [] .

In your case, try using:

 JSON.parse(data).couleurCat;

Answer 2

.Try to parse the string JSON.parse(data) and try to access it.

code

 data= JSON.parse(data)
 data['couleurCat']

Answer 3

You said " but when success i get data, and this data is an array. " So you should be trying

data[0].couleurCat

You will have to specify the index of array then access the property.
