switch statement

[mcm103]

I need help with the syntax of a switch statement. I have a variable that contains a calculated value. Based on that value I want something to happen.

between 0 and 1: x happens
between 1 and 2: y happens
etc.

I am having trouble coding the case for a range.

[tt]
switch (a){
   case (a>0 && a<1):
      //x happens;
      break;
   case (a>1 && a<2) :
      //y happens;
      break;
}
[/tt]

I don't think the switch statement is what you need here. This is one place where you should use if...else if...else if. As well, what happens if the values are exactly 1 or 2 or some other integer?

if (a>0 && a<=1)
{
....
}
else if (a > 1 && a<=2)
{
.............
}
//etc.

This is what I tried and for some reason the switch will not execute. I have but the same range logic in IF/ElseIf statements and it works. I am very confused.

I don't believe the switch statement will work with ranges.

Maybe you're right. All the examples I ever saw use only string values for switch labels.
There is no anything about some limitations in Netscape JS guide though.
I don't like it so much and usually use &quot;if ... else if&quot;.
