Sorting : is it browser specific

Question

When I did sort by title for a set of array values, it gives me 3 different results in Safari,Chrome and Firefox. Why the behaviour is so? I used sproutcore framework. I have used

Array.sort(function(a,b){return function2(parameter1,parameter2,parameter3,parameter4)})

function2 compares my keyValue . function2 in turn calls another compare function to compare the values of the record. This function returns 1 , -1 or 0 based on

record1.localeComapre(record2)

Answer 1

How do you know that you're getting different results?

The experience of other folks suggests that the behavior of localeCompare deviates between the browsers. See http://blog.schmichael.com/2008/07/14/javascript-collation-fail/ for example, as well as http://code.google.com/p/v8/issues/detail?id=459

Without seeing in more detail how your comparator works, I can't suggest more at this time. You could write a quick-and-dirty check afterwards and confirm that the lists are truly sorted; if the results come out positive, then the differences can be attributed to the quirks of localeCompare or the stability of the sorting routine.
