Menggunakan kanvas javascript untuk mencipta kemahiran applet_javascript grid sembilan persegi

/*
*canvasid:html id teg kanvas
*imageid:html img tag id
*gridcountX: Bilangan pembahagian imej paksi-x
*gridcountY: bilangan pembahagian imej paksi-y
*ruang grid:Ruang grid
*offsetX: x*y grid relatif kepada kanvas (0, 0) X koordinat mengimbangi
**offsetX: grid x*y relatif kepada kanvas (0, 0) koordinat Y mengimbangi
*isanimat: Sama ada untuk mendayakan paparan animasi
