We can use array like below and check it, this method is reduce your code size and avoid confusions.
Normally we using (Wrong Method)
<script>
function check() {
var num = 4;
if (num == 1 || num == 2 || num == 3 || num == 4 || num == 5 || num == 6 || num == 7 || num == 8 || num == 9)
{
alert("This is the number");
}
}
</script>
<input type="button" value="Check the Value" onclick="check();" />
Best Method
Which values want to check insert it to a array and find the index value of the variable, if it it not equal to -1 the condition is true other wise the condition is wrong.
