I am building a Tic Tac Toe game. My problem is being unable to clear the innerHTML of multiple divs (div class .cell) when clicking the resetButton. The divs I am trying to clear are the children of gameDisplay.
When I tried to locate the cell elements in my chrome dev tool, I get an HTML Collection:

I am having difficulty accessing the innerHTML of these elements. I currently have my resetGame() function returning gameDisplay.innerHTML=""(line 79) however, that removes all of the content of the parent element and removes my grid(board) completely. I know that is not specific enough. As a result, I tried returning gameDisplay.children.innerHTML =""; instead but nothing happens in the DOM or in my chrome dev tools console.
How can I access the innerHTML of these divs and remove the HTML inside of them using the resetGame function?
JS
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);
});

>Solution :
In your resetGame function you should loop over all the cells and remove their content instead of deleting the whole game-board content.
for(let i =0;i < gameDisplay.children.length;i++) {
gameDisplay.children[i].innerHTML = '';
}
