JavaScript alphabetical sorting (A is less than a)
Posted by fr3dr1k | Filed under AJAX, Web Development, Web Technologies
So A < a, which means if you use the sort() function and your array contains elements starting with upper and lowercase then the uppercase will appear first, i.e.:
Art, ASP.NET, LawDeed, LINQ will appear as:
ASP.NET
Art
LawDeed
LINQ
To get this working correctly you need the following function:
charOrdA: function(a, b) {
a = a.toLowerCase(); b = b.toLowerCase();
if (a > b) return 1;
if (a < b) return -1;
return 0;
}
This function will make sure your alphabetical sortorder is correct so that the list appears like this:
Art
ASP.NET
LawDeed
LINQ
You have to pass the function name to the sort function like this:
arrCategories.sort(charOrdA);
Note that there are no parenthesis.
