Javascript conditional switch statement

Question

Is there a way to write a conditional switch statement in javascript?

I\'m guessing not, since the following is always going to default:

    var raw         


        

Answer 1

No, the switch statement does not work used like that. However, this statement is not always simpler. For example, the switch version takes 15 lines:

var raw_value = 11.0;
switch(raw_value) {
    case (raw_value > 10.0):
      height = 48;
      width = 36;
      break;
    case (raw_value > 5.0):
      height = 40;
      width = 30;
      break;
    default:
      height = 16;
      width = 12;
      break;
}

and the "long" if/else version only 11:

var raw_value = 11.0;
if (raw_value > 10.0) {
      height = 48;
      width = 36;
} else if (raw_value > 5.0) {
      height = 40;
      width = 30;
} else {
      height = 16;
      width = 12;
}

So in your case, it is better to use the second one than the first...
