Why won't Safari 5 sort an array of objects?

Question

Anyone know why Safari 5 (Windows 7) can\'t sort arrays of objects?

var arr = [{a:1},{a:3},{a:2}];
console.log(arr[0].a+\',\'+arr[1].a+\',\'+arr[2].a);
arr.s         


        

Answer 1

Your comparison function is wrong:

function(a,b){return a.a > b.a;}

The function is expected to return negative, zero or positive depending on whether a < b, a = b or a > b. Your function returns a boolean indicating whether a > b. Try something like:

function(a,b){return a.a - b.a;}
