Switch in function doesn't work
Question
I wrote this just to learn the switch method, but for some reason it doesn't work as I intended, my function doesn't do anything. All I wanted to do is write a number in the value, the value then is checked in the switch method, and in case it's greater than zero, display a message, less than zero another message and so on.
Here is the whole thing
<!DOCTYPE html>
<html>
<body>
<p>Check if your number in relation to 0</p>
<input id="in"></input>
<br>
<button onclick="check()">Check</button>
<p id="display"></p>
<script>
function check() {
var text;
var val = document.getElementById("in").value;
switch (true) {
case (val < 0);
text = "Numarul este mai mic decat zero";
break;
case (val > 0);
text = "Numarul este mai mare decat zero";
break;
default:
text = "Numarul este egal cu zero";
break;
}
document.getElementById("display").innerHTML = text;
}
</script>
</body>
</html>
The text in that language is just saying the number is less greater or equal to zero, doesn't matter, I forgot to translate it in English.

Please change ; after the case to :
case val > 0:
// ^
(You do not need parenthesis between case and : )

case (val > 0); should be case (val > 0): . You end a case statement with a colon, not semi-colon.
