Underscore.js sort an array of objects alphanumerically

Question

I have an array of objects and I\'m trying to sort them alphanumerically, take the following example:

var objs = {
    \'obj1\': {\'name\': \'Object21\'},
           


        

Answer 1

You will need to create your own iterator function and then use it, you can't actually do this with the iterator function, but you can get close to it:

var objs = {
    'obj1': {'name': 'Object21'},
    'obj2': {'name': 'Object140'},
    'obj3': {'name': 'Object28'},
    'obj4': {'name': 'AnObject251'}
};

_.sortBy(objs, function(obj) {
    var cc = [], s = obj.name;
    for(var i = 0, c; c = s.charAt(i); i++) 
        c == +c ? cc.push(+c) : cc.push(c.charCodeAt(0));
    return +cc.join('');
});

> Object21
  Object28
  Object140
  AnObject251

"AnObject251" goes on the last place because of its length.
