In your code, the gridBackup is dirty when the findThePath function is called for the second time. So the subsequent calls to findThePath will not return the correct answer.

To correct it, you should make a clone of the grid every time before the pathfinding. See Line 17 of my modified version: http://jsfiddle.net/UYyQM/1/

from pathfinding.js.

Oh excellent! I don't know why that works, but it does. Much thanks to
you for the help. :) You've offered up a great script.
