```
$("#cars option").map(function(){ return this.value }).get()
``` | You can get the children of the div id **cars** by using `.children()`, or simply `$(#cars option)`:
```
var ary = [];
$('#cars').children().each(function () {
ary.push($(this).val()); //put them in array
});
```
And you can access the children with `$(this).val()`, and store them in an array |
