JavaScript Sudoku Solver

Sudoku is a puzzle that appears in my
local newspaper. As humans are asked to do, the script in this page attempts to
fill in the grid so that every row, every column, and every 3x3 box contains the
digits 1 through 9. You may be able to improve your Sudoku solving skills by
studying the steps toward a solution produced by this script.

To use the script, fill in the cells in the initial grid with the values from
your puzzle, and then push the solve button. A generated grid cell contains
either a non-zero digit when the value of the cell has been determined, a
sequence of non-zero digits when the digits omitted have been eliminated as
possibilities, or a period when no possibilities have been eliminated. A cell
contains a question mark if the grid is inconsistent.

A puzzle written in text can be loaded into the initial grid. Paste the
puzzle into the multiple row text area below the grid, and then push the load
button. The script ignores white space, and the characters hyphen, vertical
bar, and plus sign. It also ignores comments surrounded by parentheses. What
should be left is eighty-one non-zero digits and periods, which are entered into
the initial grid.
