What am I doing wrong? It is not sorting right.
JavaScript:
function sortDescending(a, b) {
var date1 = $(a).data('date');
var date2 = $(b).data('date');
return date1 > date2;
}
$('#orderaz').on('click', function () {
$('#jo .item').sort(sortDescending).appendTo('#jo');
});
A callback passed to the sort function should return a positive number if the first argument is strictly greater than the second (according to your sorting needs), a negative number if it's smaller, and 0 if they're equivalent.
You're not doing this. You're just returning whether the first argument is greater then the second. In short, you're returning a boolean, which is converted then into a number where true == 1 and false == 0.
In other words, you never return a negative value when it's needed, and this causes the issue.
Try this:
return date1 - date2;
It's a common trick for numeric sorting.
