jQuery AdminDouble List

These two js functions do the job while using jQuery with admin double list

function double_list_move(src, dest)
{
    var L = $(src).children();
    $(L).each(function(i){
        if(L[i].selected){
            $(dest).append('<option value="'+$(L[i]).val()+'">'+ $(L[i]).text()+'</option>');
            $(L[i]).remove();
        }
    });
 
}
 
function double_list_submit()
{
    var sel = $("form").find("select.sf_admin_multiple-selected");
    var C = $(sel).children();
    $(C).each(
        function(i){
            if(!C[i].selected)
                C[i].selected=true;
        }
    );
 
}
