retrieve json data from Ext.Ajax.request ????

[sendy]

Hy,
I want to retrieve latitude and longitude from
[{"latitude":"36.7708","longitude":"10.2272"},{"latitude":"36.8188","longitude":"10.166"},{"latitude":"36.8188","longitude":"10.166"}]




This is the code:
Ext.Ajax.request({
url: 'http://localhost/UniversiteCakeUploadEssai/app/webroot/getPositions.php',
method: 'post',
withCredentials: true,

params: {
classe:classe

},

success: function (response) {

var positionResponse = Ext.JSON.decode(response.responseText);
console.log(positionResponse);//it render Object {status: "success", message: "[{"latitude":"36.7708","longitude":"10.2272"},{"la…66"},{"latitude":"36.8188","longitude":"10.166"}]"}
var msg=positionResponse.message;
console.log(msg);// [{"latitude":"36.7708","longitude":"10.2272"},{"latitude":"36.8188","longitude":"10.166"},{"latitude":"36.8188","longitude":"10.166"}]


if (positionResponse.status === "success") {
console.log(positionResponse.message['latitude']); //undefined



me.sessionToken = positionResponse.sessionToken;

console.log('Success');
}
else {

console.log('Failure');

}
},
failure: function (response) {
me.sessionToken = null;
me.signInFailure('Login failed. Please try again later.');
}
Please how can I retrieve latitude and longitude for each user ????

});

how about

console.log(positionResponse.message[0].latitude);

message is an array with 3 objects. with ...message[0] we get the 1. object.
