我想执行一个循环/动作,直到按下一个键,然后按下我想停止该动作并调用函数getKey。有人可以建议如何做到这一点吗?
function getKey(e)
{
var pressedKey;
if (document.all) { e = window.event; }
if (document.layers || e.which) { pressedKey = e.which; }
pressedCharacter = String.fromCharCode(pressedKey).toLowerCase();
move(pressedCharacter);
}
document.onkeypress = getKey;

我希望 move() 函数连续执行,直到没有按下某个键。如果它被按下,我想用新的按下字符重新执行 move() 函数
取决于你如何循环。最简单的方法是使用interval:
var interval = window.setInterval(function () {
// do your thing, do your thing
}, 1000);
document.onkeypress = function () {
if (/* some specific character was pressed */) {
window.clearInterval(interval);
// do some other thing, other thing
}
};
