[javascript-dev] JSUI : question about Array index/value

Hi,

I'm working on a JSUI knob meant for a compressor knee. 

SO I've setted an Array with my knee settings :

var Ratio = ["1:1", "2:1", "3:1","4:1", "6:1", "10:1", "];

My goal is to be able to control this jsui knob by sending message of the knee settings (ex:10:1), rather than float or int (i.e. NOT by sending the array index).

Thus my question :

Is it possible to send a "value" to an Array, so it check if it match the content, and if positive retrieve the array index for that "value" ?

ie. for 

var Ratio = ["1:1", "2:1", "3:1","4:1", "6:1", "10:1"];
// index's are 0      1      2     3      4       5   

I send the message "3:1" and I get back the index of this value wich is  "2".

I've tried with vregexp.exec(Ratio) etc... but I lack skill in java and I have no good results.

So far, I'm doing like this :

function ratio(input)

{		 
switch (input) 
{ case "1:1": 	msg_float(0) ;break;
  case "2:1": 	msg_float(1) ;break;
  case "3:1":	msg_float(2) ;break;
  case "4:1":	msg_float(3) ;break;
  case "6:1":	msg_float(4) ;break;
  case "10:1":	msg_float(5) ;break;
  case "20:1":	msg_float(6) ;break;
  case "NUKE":	msg_float(7) ;break;
}
}

This works, but I want to use this code on much bigger arrays(like for a fixed frequency knob with dozen of frequency), and it'll be hard to manage all those cases lines. Especially if I make change in the array order and number etc...

Second question :
Actually I have to pass a message with a prefix "ratio 3:1" , to enter the function ratio(input). 

Is there anyway to make it work just by sending a single symbol "3:1" ? Is is possible at all to send single symbol message to jsui ?


Thanks for any help or advice !
