For JavaScript arrays, you use push() .

(对于JavaScript数组,使用push() 。)

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

For jQuery objects, there's add() .

(对于jQuery对象,有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.

(请注意,虽然push()就地修改了原始数组,但add()返回一个新的jQuery对象,它不会修改原始数组。)
