I have a button that triggers an onclick function:
<!DOCTYPE html>
<body>
<h2>what can javascript do?</h2>
<p Id="demo"></p>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.1/jquery.min.js"></script>
<script>
<button type="button" onclick='document.getElementById("demo").innerHTML = "Hello Javascript!"'>Click Me!</button>
</script>
</body>
</html>
when clicking the button, I found that the onclick does not trigger. What might be the problem with my code?
<html> tags etctype="button" on a Button Element (since by default is of type "submit")<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8" />
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Demo</title>
</head>
<body>
<h2>what can javascript do?</h2>
<button type="button" id="demoButton">Click Me!</button>
<p id="demo"></p>
<script>
const elDemo = document.querySelector("#demo");
const elButton = document.querySelector("#demoButton");
elButton.addEventListener("click", () => {
elDemo.textContent = "Hello Javascript!"
});
</script>
</body>
</html>
