javascript - 输入 "no"后窗口不会关闭？ JavaScript

Question

有人可以帮我找出代码中的错误吗？完成游戏后输入“否”时，窗口不会关闭，我似乎找不到错误。对于上下文:我试图制作一款战舰游戏并使其与 javascript 交互。当船被击中时，用户应该可以选择再次玩(窗口重新加载就好)，如果用户决定不再玩，他只需输入“否”，窗口就会关闭，但是由于某种原因这不起作用。无论我做什么，我似乎都找不到错误。有经验丰富的人有想法吗？

var table = document.getElementById("buttons");

var len_board = document.getElementsByClassName("tr").length;

var button = document.getElementsByClassName("location")

//Places ships on the board randomly
function placeShips(len_board) {
   window.random_row = Math.floor(Math.random() * (len_board - 1)) + 1;
   window.random_column = Math.floor(Math.random() * (len_board - 1)) + 1;
};


//Save users choice and determine if ship is hit
function  getId(element) {
   var chosen_row = element.parentNode.parentNode.rowIndex
   var chosen_column = element.parentNode.cellIndex

   if ((random_row == chosen_row) && (random_column == chosen_column)) {
        element.style.backgroundColor = 'red';
        element.style.borderColor = 'red';
        element.textContent = "X";
        alert("you hit my ship");
        var answer = prompt("Would you like to play again? Enter 'Yes' for 
        yes and 'No' for no:");
        var answer = answer.toLowerCase();
        if (answer == "yes") {
            location = location;
        }

        else if (answer == "no") {  
            window.close();
        }

        else {
            var reply = prompt("I'm sorry, " + answer + " is not a valid 
            input. Please try again: ");
            var reply = reply.toLowerCase();
            if (reply == "no") {
                window.close();
            }
            else if (answer == "yes") {
                location = location;
            }
            else {
                window.close();
            };
        };
   }

   else {
      element.style.backgroundColor = "#a9c8f9";
      element.style.borderColor = "#a9c8f9";
   };
};

脚本只能关闭该脚本打开的窗口。您无法关闭加载脚本的主窗口。
