JavaScript Enter key input result disappears

I've got a problem with my code. I can detect the Enter key press in an input text element (or whatever it's called) but I only get to see the result briefly and then it disappears.
So my question is, why is this happening?
Thanks.
HTML: 
<!DOCTYPE html>
<html>
<body>
<style>
#myresult
{border: 1px solid;min-height: 100px;width: 500px;text-align: left;}
</style>
<form id="myform">
<input id="myinput" type="text" onkeypress="clickPress(event)">
</form>
<script>
function clickPress(event) {
    if (event.key == "Enter") {
    document.getElementById("myresult").innerHTML = "You pressed the Enter key."
    }
}
</script>
<br>
<p id="myresult" ></p>
</body>
</html>

Because the form is submitted by pressing this key.

Oh okay. If necessary, I'll read more about forms later on.

You know, after reading your post/link (thank you for the javascript code - which I did try out) I was thinking 'Do I really need a form element if I've only got one input box?' So I tried it and it worked....
HTML: 
<!DOCTYPE html>
<html>
<body>
<style>
#myresult
{border: 1px solid;min-height: 100px;width: 500px;text-align: left;}
</style>
<input id="myinput" type="text" onkeypress="clickPress(event)">
<script>
function clickPress(event) {
    if (event.key == "Enter") {
    document.getElementById("myresult").innerHTML = "You pressed the Enter key."
    }
}
</script>
<br>
<p id="myresult" ></p>
</body>
</html>

But if I don't include this form element, would that cause problems in the future if I decide to do server side stuff like mySQL and PHP?

Thanks again Padonak 🙂

Best practice is to use form element for anything server-side, so unfortunately, yes, you're still stuck with it
