排序选择选项元素

Question

I'm having an issue with sorting my select list elements.. In fact I have two dependent lists one with a list of "models" which I have sorted successfully using this function:

var sel = $('#model');
var opts_list = sel.find('option');
opts_list.sort(function(a, b) { return $(a).text() > $(b).text() ? 1 : -1; });
sel.html('').append(opts_list);

But the second list contains the versions of the chosen model with the build number between brackets...

Examples:

 2.00.312 (11)  
 5.105.402 (43)
 2.05.105 (141)
 4.54.200 (151)
 2.35.504 (61)
 1.204.454 (10)

Answer 1

a regex made the job:

FIDDLE

items[value].sort(function (a, b) {
    a = Object.keys(a)[0].replace(/\(([^)]+)\)/,"").replace(/\./g,"");
    b = Object.keys(b)[0].replace(/\(([^)]+)\)/,"").replace(/\./g,"");
    console.log(a,b);
    return a > b ? 1 : -1;
});
