In PHP, a class can implement the ArrayAccess interface, so the class can be instantiate and accessed like:
class MyClass implements ArrayAccess {
protected $data = array();
public function offsetGet($offset) {
return isset($this->data[$offset]) ? $data[$offset] : null;
}
public function offsetSet($offset, $value) {
$this->data[$offset] = $value;
}
public function __toString()
{
return print_r($this->data);
}
}
$a = new MyClass;
$a['item'] = 10;
$a['item2'] = 'adsf';
echo $a;
// Outputs Array( 'item' => 10, 'item2' => 'adsf' )
Is there anything like this in Javascript? I want to be able to create an iterator class in Javascript, but the items can be accessed by using the bracket notation instead of using get('item')/set('item2', 'asdf') so it can act like an Array instead of an Object, but still having all the functions from my constructor (next, prev, is, reset, etc)
I'm asking this because AngularJS, when using angular.element(), it returns an object (?) like Object [div.id1] in firebug console
