Randomize a List - is this possible?

[graysonr56202133]

I want to create a fillable form  as a sign up list of players.  After gathering X number of players, I would like to randomize as follows:

Sign ups:

Player 1 - Ann

Player 2 - Bob

Player 3 - Carl

(then, I assume, a button to iniiate randomizing the above with the results below:)

Randomize List:

Player 1 - Carl

Player 2 - Ann

Player 3 - Bob

Hopefully, the above example explains my desire.  Is this possible?  I can do it in Excel, but would like a fillable form application to to it.  Suggestions?

Thank you in advance.

How do you enter names?

You want to show random names in list box?

Sign ups via a fillable list of text boxes #1 through #4 for a team doubles tournament.

By randomizing players, the partner selection will also become randomized, thus insuring the competitions

aren't stacked in favor os those working the system.  Hope that makes sense.

The below schedule is set and won't change.  I want to alleviate players choosing which slot they may fill.

Round 1

#1 & #2  -v-  #3 & #4

Round 2

#1 & #3  -v-  #2 & #4

Round 3

#1 & #4  -v-  #2 & #3

For this example, what I envision is four text bozex for the player snames to be entered.  A button that will initiate a scripot to randomize, then the results to be displayed as above with player names instean of numbers.

I apologize for the "fat finger" spelling mistakes above.  I have little experience with Javascript and really don't know if this is even possible.  Just asking.

Try this code:

var maxFields = 4;
var values = [];
for (var i=1; i<=maxFields; i++) {
	var v = this.getField("Text"+i).valueAsString;
	if (v!="") values.push(v);
}

var newValues = [];
var usedIndexes = [];
while (newValues.length<values.length) {
	var randomIdx = Math.floor(Math.random()*values.length);
	while (usedIndexes.indexOf(randomIdx)!=-1)
		randomIdx = Math.floor(Math.random()*values.length);
	newValues.push(values[randomIdx]);	
	usedIndexes.push(randomIdx);
}

for (var i=1; i<=maxFields; i++) {
	if (i<=newValues.length) this.getField("Text"+i).value = newValues[i-1];
	else this.getField("Text"+i).value = "";
}

Where does this code go though..?

You can use it in a button as 'Mouse UP' action.
