將製作ejcees（中國象棋打譜程式）
Re: 將製作ejcees（中國象棋打譜程式）
一個小問題：如果打開的json輪到黑方，則第一行要改為「特定局面，輪到黑方」。

// Deep clone the entire game tree for undo/redo
function cloneGameState() {
return {
historyFEN: JSON.parse(JSON.stringify(historyFEN)),
currentBranch: [...currentBranch],
currentStepIndex: currentStepIndex
};
}
function saveStateToUndo() {
undoStack.push(cloneGameState());
if (undoStack.length > 50) undoStack.shift(); // limit history size
redoStack = []; // clear redo on new action
}
function restoreState(state) {
historyFEN = state.historyFEN;
currentBranch = state.currentBranch;
currentStepIndex = state.currentStepIndex;
renderRecordUI();
renderNoteUI();
jumpToStep(currentStepIndex);
}
function undo() {
if (undoStack.length === 1) return;
const previous = undoStack.pop();
redoStack.push(previous);
restoreState(undoStack[undoStack.length - 1]);
}
function redo() {
if (redoStack.length === 0) return;
const next = redoStack.pop();
undoStack.push(next);
restoreState(next);
}
在以上代碼中，如果我走到第二步，之後走一下undo和redo，然後往後走到第四步或更多，當我undo回到第二步時，historyFEN跟當前最後一步是一樣的。
懷疑是深複製存在問題。
請查找問題原因，並說出如何修複。https://ejsoon.vip/

Re: 將製作ejcees（中國象棋打譜程式）
一，為#tool-rotate和#tool-flip增加點擊功能，點擊之後高亮，再點擊取消高亮。
#tool-rotate使所有棋子位置中心旋轉，#tool-flip為所有棋子位置左右對稱。
這兩個功能都不會影響.ejceesrecord的文字描述即棋譜，也不會記錄到historyFEN中，亦不記錄到undo、redo中。
當點擊ejceesstep內的按鍵時，棋子位置也會因旋轉或對稱而發生變化。
二，tool-btn處於非高亮狀態時，把顏色調得更暗。
tool-new：當有至少一步棋，或初始狀態與INITIAL_FEN不同時高亮。
tool-open：一直高亮。
tool-edit：當處於非編輯狀態時高亮。
tool-save：跟tool-new相同。
tool-undo：當undoStack.length>1時高亮。
tool-redo：當redoStack.length>0時高亮。
tool-rotate：當處於rotate狀態時高亮。
tool-flip：當處於flip狀態時高亮。
tool-exp-txt：一直高亮。
tool-exp-svg：一直高亮。
建立一個切換按鍵高亮的函式，在事件觸發的時候使用。
三，只需給出要修改的地方，所有的代碼和注釋都要使用英文。
