Switch statement range EX: case 90 to 100

How do you do a range using switch statement in ActionScript

For example:

score = txtScore.text
switch(score)
{
case 90 to 100: // how do you set the range?
txtScore.text = “A”;
break;
}

Thanks

you dont. All case comparisons are done through a strict equality (i.e. === ). You might just have to use if/else.

It can be done. You have to be a little creative though. Here’s some code for something like that.

on(release)
{
intNew = (parseInt(txtScore.text) / 10)

switch(parseInt(intNew))
{
	case 10:	txtGrade.text = "A";
		break;
	case 9:	txtGrade.text = "A";
		break;
	case 8:	txtGrade.text = "B";
		break;
	case 7:	txtGrade.text = "C";
		break;
	case 6:	txtGrade.text = "D";
		break;
	default:	txtGrade.text = "F";
}

}

Another way to workaround the issue is to use a range function’s return value as the switch value (operand?).

For your 90-100 range, you would create a function that returns a single value for any range matches (90 in the example), and returns the original value for all others.

Example:

function rangeIt(theNumber){
return (89<theNumber && theNumber<101)?90:theNumber;
}
switch(rangeIt(myNumber)){
case 90: trace('Inside Range');break;
default: trace('Outside Range');break;
}

};

This allows the use of the switch statement on a range of values without altering the actual values.
