A small demo that uses js to capture which key is pressed on the keyboard, and then displays the corresponding code value
<!DOCTYPE html>
<html>
<head>
<script>
function showKeyCode(event)
{
document.getElementById("result").value= event.keyCode;
}
</script>
</head>
<body onkeyup="showKeyCode(event)">
<p>按下键盘上的键，文本框中会显示对应的code</p>
<input type="text" id="result" value="1" />
</body>
</html>
The above is the entire content of this article, I hope you all like it.
