Question

I have these dynamic dropdowns with dynamic ids and value.

<select id=extra['123']></select>
<select id=extra['453']></select>
<select id=extra['789']></select>

In php, I am able to get the value using:

$_REQUEST['extra']

And I get an array.

[extra] => Array
    (
        [123] => 0
        [453] => 0
        [789] => 0
    )

But how do I create an array in jquery? Thanks in advance!

Answer 1

You can use wild card

Live Demo

selectArray = $('[id^=extra]');

Iterating throuh all selects

selectArray.each(function() {
    alert(this.id);
})​

For getting the numbers in id of selects

Live Demo

selectArray = $('[id^=extra]');
ids = selectArray.map(function() {
    return this.id.replace("extra['", "").replace("']", "");
}).get().join();
alert(ids);
