I have a multidimensional array. The primary array is an array of
[publicationID][publication_name][ownderID][owner_name]
What I am trying to do is sort the array by owner_name
and then by publication_name
. I know in JavaScript you have Array.sort()
, into which you can put a custom function, in my case i have:
function mysortfunction(a, b) {
var x = a[3].toLowerCase();
var y = b[3].toLowerCase();
return ((x < y) ? -1 : ((x > y) ? 1 : 0));
}
This is fine for just sorting on the one column, namely owner_name, but how do I modify it to sort on owner_name
, then publication_name
?
If owner names differ, sort by them. Otherwise, use publication name for tiebreaker.
function mysortfunction(a, b) {
var o1 = a[3].toLowerCase();
var o2 = b[3].toLowerCase();
var p1 = a[1].toLowerCase();
var p2 = b[1].toLowerCase();
if (o1 < o2) return -1;
if (o1 > o2) return 1;
if (p1 < p2) return -1;
if (p1 > p2) return 1;
return 0;
}
