Sort Options in a Select List with javascript/jQuery.. but not alphabetically

Question

I am looking for a function that will take a list of options in a select list and sort them alphabetically but with a twist. All values with the text \'NA\' should be pushed to

Answer 1

I've made ​​some changes to the original function and it worked fine.

function NASort(a, b) {  
    console.log(a.innerHTML.substr(0, 1).toLowerCase() + ' > ' + b.innerHTML.substr(0, 1).toLowerCase());
    return (a.innerHTML.substr(0, 1).toLowerCase() > b.innerHTML.substr(0, 1).toLowerCase()) ? 1 : -1;
};

$('select option').sort(NASort).appendTo('select');
