AngularJS Convert Array to JSON

rated 0 times [ 199] [ 3] / answers: 1 / hits: 21953 / 10 Years ago, wed, march 5, 2014, 12:00:00

I have an array containing 3 elements

var a = [];

  a[username]=$scope.username;

  a[phoneNo]=$scope.phoneNo;

  a[altPhoneNo]=$scope.altPhoneNo;

Now, I want to send this data to server in JSON format. Therefore, I used

    var aa = JSON.stringify(a);

    console.log(aa = +aa);

But the console displays empty array

aa = []

How can I convert this array into JSON?

That's not the correct way to add elements to an array, you're adding properties instead.
If you did console.log(a.username); you'd see your $scope.username value.

You could either do

var a = [];

a.push({username: $scope.username});

a.push({phoneNo: $scope.phoneNo});

a.push({altPhoneNo: $scope.altPhoneNo});

But it looks more like what you're trying to do is

var a = {};

a[username] = $scope.username;

a[phoneNo] = $scope.phoneNo;

a[altPhoneNo] = $scope.altPhoneNo;

That is, you want your a to be an object if you're going to add properties to it.
And that would be better written as

var a = {};

a.username = $scope.username;

a.phoneNo = $scope.phoneNo;

a.altPhoneNo = $scope.altPhoneNo;
