I am currently making a simple online text editor site. And I cannot detect backspace being pressed. Here is the code: HTML
<!DOCTYPE html>
<html>
<head>
<link rel="stylesheet" href="cssfile/style.css">
<title> Code Editor </title>
<script src="jsfile/main.js"></script>
<meta name="viewport" content="width=device-width, initial-scale=1.0">
</head>
<body>
<div class="navdiv"></div>
<div id="board" class="board">
</div>
</body>
</html>
js: This is my main code:
document.addEventListener("keypress", function (event) {
console.log(event.key)
if (event.key == "Enter") {
document.getElementById("board").innerText += '\n'
} else {
document.getElementById("board").innerText += event.key
}
});
This is my code and I tried
if(event.key == "Backspace")
But that didn't work.
You are close.
You are using keypress when you should be using keyup (or keydown if you want to know before the key press is complete).
KeyPress event is invoked only for character (printable) keys, KeyUp and KeyDown events is raised for all including non-printable such as Control, Shift, Alt, BackSpace, etc.
Try this:
document.addEventListener("keyup", function(event) {
console.log(event.key);
if (event.key === "Backspace") {
document.getElementById("board").innerText += '\n'
} else {
document.getElementById("board").innerText += event.key
}
});
keypress event has been deprecated and there's a change your browser doesn't support it. Use keydown instead.
document.addEventListener("keydown", function (event) {
console.log(event.key)
if (event.key == "Backspace") {
document.getElementById("board").innerText += '\n'
} else {
document.getElementById("board").innerText += event.key
}
});
The keypress event is deprecated and triggers only when a key press produces a character value. Thus, it is not triggered with the backspace in your case.
You should use the keydown event.
