Javascript lets you pass a comparison function to the Array.sort
function, so you can do specific types of sorting by writing a
function that will determine which item should go where in the list.
This function will sort based on the title:
function sortTitle(a, b) {
if (a.title > b.title) return 1;
else if (a.title < b.title) return -1;
else return 0;
}
items.sort(sortTitle);
To emulate ActionScript's Array.sortOn method, you can add it into
the Array prototype, like so:
Array.prototype.sortOn = function(key) {
return this.sort(function (a,b) {
if (a[key] > b[key]) return 1;
else if (a[key] < b[key]) return -1;
else return 0;
});
}
items.sortOn('title');
items.sortOn('year');
