javascript - 在特定点之后忽略用户输入

Question

在宣布获胜者后，有什么方法可以杀死/中断我的井字游戏板上的用户输入吗？在发送谁获胜的警报后，我尝试在 isFull() 函数中使用break，但它仍然会接受表后的用户输入。

这是一个向您展示它正在运行的链接: https://jsfiddle.net/n1kn1vLh/2/

function TicTacToe() {
  this.board = [
    [0, 0, 0],
    [0, 0, 0],
    [0, 0, 0]

tic = new TicTacToe();
tic.showhtml();

当有人获胜时，您可以删除 eventListener:

function isFull() {
    for (var i = 0; i < tic.board.length; i++) {
      if(tic.board[i][0] == tic.board[i][1] && tic.board[i][0]==tic.board[i][2] && tic.board[i][0]!=0){
        alert(tic.board[i][0]+" Wins");
        document.getElementById("tictable").removeEventListener('click', clickHandler);
        return;
      }
  }

  for (var i = 0; i < tic.board.length; i++) {
      if(tic.board[0][i] == tic.board[1][i] && tic.board[0][i]==tic.board[2][i]  && tic.board[0][i]!=0){
        alert(tic.board[0][i]+" Wins");
        document.getElementById("tictable").removeEventListener('click', clickHandler);
        return;
      }
  }

  if(tic.board[0][0]==tic.board[1][1] && tic.board[0][0] == tic.board[2][2]  && tic.board[0][0]!=0){
    alert(tic.board[0][0]+" Wins");
    document.getElementById("tictable").removeEventListener('click', clickHandler);
    return;
  }

  if(tic.board[0][2]==tic.board[1][1] && tic.board[0][2] == tic.board[2][0]  && tic.board[2][0]!=0){
    alert(tic.board[1][1]+" Wins");
    document.getElementById("tictable").removeEventListener('click', clickHandler);
    return;
  }
}
