Add to Array jQuery

Question

I know how to initliaize one but how do add I items to an Array? I heard it was push() maybe? I can't find it...

Are you asking how to add elements to an Array, or how to add elements to a jQuery object? — Phrogz, May 02 '11 at 20:01
@Jahkr: You're also probably sitting on a chair whilst doing it, but that doesn't mean that the question is relevant to Ikea. Don't be misled thinking that jQuery is a separate language; it is not. You're still writing Javascript. You just happen to be using things from the jQuery library (in _other parts_ of your code). — Lightness Races in Orbit, May 02 '11 at 20:10

For JavaScript arrays, you use push().

var a = [];
a.push(12);
a.push(32);

For jQuery objects, there's add().

$('div.test').add('p.blue');

Note that while push() modifies the original array in-place, add() returns a new jQuery object, it does not modify the original one.

+1 for explaining both JavaScript and jQuery's method and their fundamental difference. I came here for `$.add()` and got just a little bit more. – Sam Feb 01 '14 at 00:21

push is a native javascript method. You could use it like this:

var array = [1, 2, 3];
array.push(4); // array now is [1, 2, 3, 4]
array.push(5, 6, 7); // array now is [1, 2, 3, 4, 5, 6, 7]

You are right. This has nothing to do with jQuery though.

var myArray = [];
myArray.push("foo");
// myArray now contains "foo" at index 0.

nice, but how do I add foo at index 'customString' ? – Andrei Cristian Prodan Oct 21 '12 at 15:58
ha! I found it myArray.push( {'index':'value'} ); – Andrei Cristian Prodan Oct 21 '12 at 16:01
But that is no longer array then, myArray turns into object? – SubjectX Nov 12 '15 at 12:24

For JavaScript arrays, you use Both push() and concat() function.

var array = [1, 2, 3];
array.push(4, 5);         //use push for appending a single array.




var array1 = [1, 2, 3];
var array2 = [4, 5, 6];

var array3 = array1.concat(array2);   //It is better use concat for appending more then one array.
