There are three common ways how to use onkeypress event:
- with event listener,
- with element attribute,
- with element property.
1. Event listener based example

<body>
<p>Type something: </p>
<input type="text" id="my-input">
<script>
var myInput = document.querySelector('#my-input');
myInput.addEventListener('keypress', function() {
console.log('onkeypress event occurred.');
});
</script>
</body>
</html>
