for (var j=0; j<3; j++) {
kvadratiki[i][j] = document.getElementById('game').innerHTML+='<div class="block"></div>';
};
};
};
var hod = 0;
document.getElementById('game').onclick = function(event){
console.log(event);
if (event.target.className == 'block'){
if (hod%2==0) {
event.target.innerHTML = 'x';
}
else {
event.target.innerHTML = '0';
}
hod++;
checkWinner();
}
}
var n;
var m;
function checkWinner(){
var block = document.getElementsByClassName('block');
for (var n=0; n<i; n++) {
for (var m=0; m<j; m++) {

alert('X WINS')
}
}
}
};

Its fieldd 3x3, when you click it - you put 'x' or '0' in one of blocks I want to type code that allows me to check, if i have all 'x' or '0' in row or column or in diagonal, for example field 3x3 - field ij:
00 01 02
10 11 12
20 21 22
I cant understand how to get elements like :
[i][j],[i+1][j+1] - diagonal
[i][j], [i][j+1] -row
[i][j], [i+1][j] -column
I want to set alert if 00, 11,22 - have 'x' and if 00 01 02 - as well and 00 10 20 - as well
