tic-tac-toe

This is simple tic-tac-toe game front end with html and javasript Simply open ttt.html

There's a RESTART button We select these cell using js document object

var cells = document.getElementsByTagName('td')

This outputs HTMLCollection of td

HTMLCollection(9) [td, td, td, td, td, td, td, td, td]

On clicking the restart button, that event triggers clearBoard() function

function clearBoard(){
	for(var i=0;i<cells.length;i++){
		cells[i].textContent = '';
	}
}

restart.addEventListener('click', clearBoard)

At the core of the game, lies the changes in the cells depending on the click of the mouse. This is the event listener thats responds to the click on the board

for(var i =0;i<cells.length;i++){
	cells[i].addEventListener('click', clickBoard)
}

And this is the function it calls

function clickBoard(){
	if(this.textContent == ''){
		this.textContent = 'X'
	}else if(this.textContent == 'X'){
		this.textContent = 'O'
	}else{
		this.textContent = ''
	}
}

So on first click, is converted to X and if you click one more time then X is converted to O and on third click O is converted to
