jQuery search class from a list of specified classes

I have div with 6 classes. I want to know if that div has either class one, two , three, or four and set that as the value of the select box. I only want to search for these 4 classes and don't care about the other classes in the div. I have the following. Is there a better way to write it. 

<div class="four whatever something"></div>

<select>
    <option>one</option>
    <option>two</option>
    <option>three</option>
    <option>four</option>
</select>

if ($('div').hasClass(one)) {
    $('select').val('one')
} else if ($('div').hasClass('two')) {
    $('select').val('two')
}
if ($('div').hasClass('three')) {
    $('select').val('three')
}
if ($('div').hasClass('four')) {
    $('select').val('four')
}

You could try something like that:

var classes = $('div').attr('class').split(/\s/);
for ( var i in classes )
        $('select').val(classes[i]);

Of course there is a better way to write it. You'd probably like to know what that way is, though. :)

var classes = ['one', 'two', 'three', 'four'],
    $div = $('#myDivId');

for (var i=0; i<classes.length; i++)
{
    if ($div.hasClass(classes[i]))
    {
        $('select').val(classes[i]);
        // break;
    }
}

The break; is commented out to make the looped version match your current code. However, if you meant to use if...else if...else if...else if instead of if...if...if...if, the break is necessary.
