我在做一个Tic Tac脚趾游戏。我的问题是在单击innerHTML时无法清除多个div (div类.cell)的resetButton。我想澄清的是gameDisplay的孩子们。

当我试图在我的chrome工具中定位单元格元素时，我得到了一个HTML：ScreenShot在这里

我在访问这些元素的innerHTML时遇到了困难。目前，我的resetGame()函数返回gameDisplay.innerHTML=“(第79行)，这将删除父元素的所有内容，并完全删除网格(板)。我知道这还不够具体。因此，我尝试返回gameDisplay.children.innerHTML =""；但是在DOM或我的chrome工具控制台中什么都没有发生。

我如何访问这些div的innerHTML并使用resetGame函数删除其中的resetGame？

const playerFactory = () => {
    const playTurn = (event, currentPlayer) => {
      const id = boardObject.cells.indexOf(event.target);
      boardObject.boardDisplay[id] = currentPlayer;
      boardObject.render();
    };
  
    return {
      playTurn
    };
  };
  
  // Gameboard object
  const boardObject = (() => {
    let boardDisplay = ['', '', '', '', '', '', '', '', ''];
    const cells = Array.from(document.querySelectorAll(".cell"));
    // displays the content of the boardArray
    const render = () => {
      boardDisplay.forEach((cells, idx) => {
        cells[idx].innerHTML = boardDisplay[idx];
      });
    };
    return {
      boardDisplay,
      render,
      cells
    };
  })();


  // Create Array from DOM
const boardArray = [...document.querySelectorAll(".cell")].map(cells=>cells.innerHTML);
console.log(boardArray);

// Display controller, shows which player is which
const displayController = (() => {
const playerOne = 'X';
const playerTwo = 'O';
const gameBoard = document.querySelector(".game-board");
let currentPlayer = playerOne;

const switchPlayer = () => {
    currentPlayer = currentPlayer === playerOne ? playerTwo : playerOne;
  }

  gameBoard.addEventListener("click", (event) => {
    if (event.target.classList.contains("cell")) {
      if (event.target.textContent === "") {
        event.target.textContent = currentPlayer;
        const indexOfClickedCell = Array.prototype.indexOf.call(document.querySelectorAll('.cell'), event.target);
        boardArray[indexOfClickedCell] = currentPlayer;
        switchPlayer();
             
   
      }
    }
  });
})();


const gameDisplay = document.getElementById("game-board");


// Define reset button function first
function resetGame(){

// Define result, reset the board
//if the board array index is equal to a character
if(boardArray.includes('X','O')){
    { return gameDisplay.innerHTML = "";
       
      }
}
else
  {;}
//and if the cells textContent is equal to a character
//return the result, which is the reset board function 
}

const resetButton = document.querySelector(".restart");
resetButton.addEventListener("click", (event) => {
    resetGame(event);
});

在您的resetGame函数中，您应该遍历所有单元格并删除它们的内容，而不是删除整个游戏板内容。

for(let i =0;i < gameDisplay.children.length;i++) {
    gameDisplay.children[i].innerHTML = '';
}
