Onkeypress 函数返回空格而不是字母
Onkeypress function returning spaces instead of letters
我正在使用以下内容并尝试让用户猜测的字母出现在屏幕上,但是当我检查 devtools 时,按键被返回到数组,如 [ , , , , , ,]。没有字母。想法?
var letguessText = document.getElementById("letguess")
var guessArray = []
document.onkeypress = function(event) {
var guess = event.key
guessArray.push(String.fromCharCode(guess));
letguessText.textContent = guessArray;
}
您不需要 fromCharCode 因为 event.key 是字符。这是一个例子。
var letguessText = document.getElementById("letguess")
var guessArray = []
document.onkeypress = function(event) {
var guess = event.key
guessArray.push(guess);
letguessText.textContent = guessArray;
}
<p id="letguess">Start typing</p>
