I want to limit a number between two values, I know that in PHP you can do this:
$number = min(max(intval($number), 1), 20);
// this will make $number 1 if it's lower than 1, and 20 if it's higher than 20
How can I do this in javascript, without having to write multiple if
statements and stuff like that? Thanks.
like this
var number = Math.min(Math.max(parseInt(number), 1), 20);
function limitNumberWithinRange(num, min, max){
const MIN = min || 1;
const MAX = max || 20;
const parsed = parseInt(num)
return Math.min(Math.max(parsed, MIN), MAX)
}
alert(
limitNumberWithinRange( prompt("enter a number") )
)
