Question

我正在开发基于文本的游戏，window.close();是我在角色死亡时使用的。但是，当使用window.close();处理程序时，它不会关闭窗口，只是完全跳过该部分，转到其他alert / if else语句。

alert("Part 2 of game commencing.");
alert("For this part of the game, you can re-state your computer password.");

var password = prompt("Enter your new password now!");
var passwordConfirm = prompt("Confirm your password.");
if (passwordConfirm == password) {
    alert("Correct! Both passwords match.");
} else if (passwordConfirm != password) {
    alert("Both passwords do not match.");
    var newPassword = prompt("Let's try this again, retype the password you want.");
    var newPassword = password;
    var passwordConfirm = prompt("Confirm your password (don't screw it up this time     you fool)");
    if (passwordConfirm == password) {
        alert("Correct! Both passwords match.");
    } else if (passwordConfirm != password) {
        alert("Wrong. You've missed your chance at getting a new password. Just use rat_race.");
    }
}

alert("You're starting to feel hungry.");
alert("You look up where you could eat for the night.");

var roomService = prompt("Do you (a) get room service or (b) eat out?");
if (roomService == "a") {
    alert("You call room service, and you ask for spaghetti.");
    alert("After five minutes, your meal arrives. You eat it.");
} else if (roomService == "b") {
    alert("You leave your room, taking your room key with you.");
    var elevator = prompt("You enter the elevator. Do you take floor B, 1, 2, 3, 4, 5     (case sensitive)");
    switch (elevator) {

            break;

Answer 1

https://developer.mozilla.org/en-US/docs/Web/API/Window.close

在说明：

下

仅允许为打开的窗口调用此方法通过使用window.open方法的脚本。如果窗口没有打开通过脚本，JavaScript控制台中出现以下错误：脚本可能无法关闭脚本未打开的窗口。

Answer 2

如果脚本没有打开窗口，则无法使用window.open。解决这个问题的一种方法是使用

window.open('', '_self', ''); 
window.close();

这将绕过某些浏览器的要求，它在chrome中运行，但我没有尝试过其他浏览器。

我建议重新考虑这一点。写入div /某种文本框对用户来说会容易得多。

window.close（）不执行
