Verwendung von reinem Javascript zur Implementierung der klassischen Minesweeper-Game_Javascript-Fähigkeiten

Vor langer Zeit geschrieben, habe ich es nur hinzugefügt (Nima, viele davon kenne ich nicht...)

Das Manko ist, dass ich ursprünglich eine Spielranking-Statistik schreiben wollte, und ich werde sie hinzufügen, wenn ich Zeit habe (es kommt mir vor, als würde ich das jedes Mal sagen und dann lange warten...)

Es gibt auch eine Funktion, die nicht implementiert wurde: Das Klicken auf das erste Raster kann keine Donnerfunktion sein
