Tut mir leid, das ist vielleicht eine sehr noobische Frage.
Ich baue für jemanden eine Schachspiel-Datenbank auf und stecke an der Ziellinie fest.
Bei mir funktioniert alles (wenn eine Standard-Schach-Forsyth-Edwards-Notation (FEN) geladen ist)
Immer wenn ich ein benutzerdefiniertes Fen aus der Datenbank lade, wird das Fen einwandfrei geladen, aber wenn Sie auf „Weiter“ klicken Dabei wird auf die Standardeinstellung zurückgegriffen.
Bitte sagen Sie mir, was ich tun kann, um dieses Problem zu beheben.

Ich habe so viele verschiedene Dinge ausprobiert.
Das Letzte, was ich versucht habe, war, das benutzerdefinierte Fen in die chess.js einzufügen
[code]var DEFAULT_POSITION = 'rnbqkbnr/pppppppp/8/8/8/8/PPPPPPPP/RNBQKBNR w KQkq - 0 1';

// Allow injection of a custom FEN for game initialization
window.setCustomFEN = function(fen) {
DEFAULT_POSITION = fen;
};
[/code]
und aktualisieren Sie die Last in der index.html
[code]window.loadPGN = function(id) {
$.getJSON('php/get_pgn.php?id=' + id, function(data) {
if (data.success) {
setCustomFEN(data.starting_fen); // ✅ Injecting the custom FEN
game = new Chess(DEFAULT_POSITION); // ✅ Using the overridden FEN
board.position(DEFAULT_POSITION);
game.load_pgn(data.pgn_data);
moves = game.history({
verbose: true
});
currentMoveIndex = 0;
$('#move-window').html(data.pgn_data);
}
});
