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).

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" ?

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

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.

{ case "1:1":     msg_float(0) ;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...

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 ?

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

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".

{		 
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;
}
}

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

I'm no expert either, but I'd have thought something along the lines of this

If you send "ratio 3:1" you'll get back "2" out the outlet.

That's odd. Just incase you're looking at the forum view not the email list here's the js code again with out the bits missing... ?!

One small thing, don't forget to declare the "i" variable with the 

var keyword, otherwise it becomes global.

I'm nt sure to understand ... You mean just adding "var i=0" inside the function ?

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

Emmanuel,
I'm nt sure to understand ... You mean just adding "var i=0" inside the function ?

Any idea about my question #2 : 
Actually I have to pass a message with a prefix "ratio 3:1" , to enter the function ratio(input). 

> I'm nt sure to understand ... You mean just adding "var i=0" inside 

if you don't use the var keyword, the variable is automatically 

declared as global (in the JavaScript meaning, not the Global 

object). And it's usually very hard to figure out the problem (for 

example, if you have 2 jsui running at the same time, they will share 

the i variable, which is really not what we want in such situation).

Have a look to the anythinng() method. The message name property 

should have the symbol "3:1". Although I didn't test, the following 

    var i; // this is really important ;-)

    for(i = 0; i < Ratio.length; i++) {

        if(Ratio[i] == messagename)

Have a look to the anythinng() method. The message name property  
should have the symbol "3:1". Although I didn't test, the following  
should work:

function anything()
{
	var i; // this is really important ;-)

	for(i = 0; i < Ratio.length;  i++) {
		if(Ratio[i] == messagename)
			outlet(0, i);
	}
}

Your help is much much apprectiated : Thanks again !
