在某個點之後忽略用戶輸入

Question

有沒有一種方法可以在宣佈獲勝者後在我的tic tac toe板上殺死/突破用戶輸入？我在嘗試使用isFull（）函數中的break後發送了警告，但是它仍然會接受用戶在表中後續字詞的輸入。

這裏是一個鏈接，告訴你它是運行： https://jsfiddle.net/n1kn1vLh/2/

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

    this.showhtml = toHTML; 
    this.player2 = "O";

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

可以刪除事件監聽某人贏時：

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; 
    } 
}

添加下面你isFull（）

document.getElementById('user input').disabled = true;
