Set selected options via JS

[dror-nahmias]

I was looking for a way to set selected options using JS.
I came up with the following:

/**
* Set selected options with the given values
*
* @param arrValues
* The value of the item(s) being selected
*/
    this.selectOptions = function (arrValues) {
        // give options correct attributes

        $selectSingle.find('option').each(function () {
            var currVal = $(this).attr('value');
            if ($.inArray(currVal, arrValues) > -1) {   
                $(this).attr({selected: 'selected', 'disabled' : 'disabled'}).data('disabled', 1);
            } else {
                $(this).removeAttr('selected').removeAttr('disabled').removeData('disabled');
            }
        });
        //empty list of selected
        $list.empty();
        // add the new selected options
        // this did not work with selected!!!
        $selectSingle.find(':disabled').each(function () {
            add($(this), null, false);
        });
    };

Don't know if it is the best way but it works.
I feel it's wrong to play around with the actual data and attributes (rather call on a function for this)
Also selecting by the selected attribute failed but was OK using the disabled attribute - weird...

Be happy to get your corrections/thoughts on this.

Thank you for creating this plugin!
