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

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

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

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

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

max v2;
#N vpatcher 15 55 615 455;
#P window setfont "Sans Serif" 9.;
#P window linecount 1;
#P message 214 132 21 9109513 4:1;
#P message 190 132 21 9109513 3:1;
#P newex 190 157 62 9109513 prepend ratio; #P number 190 203 35 9 0 0 0 139
0 0 0 221 221 221 222 222 222 0 0 0; #P newex 190 180 41 9109513 js ratios;
#P connect 3 0 2 0; #P connect 4 0 2 0; #P connect 2 0 0 0; #P connect 0 0 1
0; #P pop;


Hope that's of use,
Simon

Subject: [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 !
