Help With Validating (making what I got repeatable)

[jdubwelch]

I'm making a online march madness bracket.  I need to validate two things: 1) That every field has a value 2) That the current field is a "parent" of the previous two games.

 

There's roughly 60 games that I need to validate.

 

On a smaller scale:  Let's say each field below "A1 - A15" needs to have something it it.  When the user clicks on A1 that value in A1 (which is the team the user thinks is going to win) goes to A9.  And likewise the value of A3 or A4 will go to A10.  Then when they click on A9 or A10 it will put that value in A13, etc. 

 

A1

      A9

A2 

                A13

A3       

      A10

A4

                            A15

A5

      A11

A6

                A14

A7

      A12

A8

 

So I need to validate that the value of A7 is actually in A5 or A6. 

 

Currently I'm doing that by:

function validate_form() {
	if ( document.myForm.winnerA15.value == "" ) {
		alert ( "Please complete the form." );
		return false;
	}
	if ((document.myForm.winner15.value != document.myForm.winnerA13.value) && (document.myForm.winnerA15.value != document.myForm.winnerA14.value)) {	
		alert("Your champion is not in the championship game.");
		return false;
	}

 

Is there a way to make it repeatable?

 

I have 4 brackets: A, B, C, D

Each bracket has 15 "winners"

Okay,  So this is what I got by trial and error.  More error than anything. 

 

It doesn't seem to work.  My page just loads and doesn't do anything.

 

Any ideas?

 

function validate_form() {

	var bracketArray = new Array('A', 'B', 'C', 'D');

	for(var i=0; i<=bracketArray.length-1; i++) {
		var bracket = bracketArray[i];
		for (var j=15; j>=1; --j) {
			document.write('<p>' +  bracket + j + '<br />');
			checkTeamsBefore (bracket, j);
			document.write('</p>');
		}

	}

	return false;


}

function checkTeamsBefore (bracket, game) {

	var gameNum = 16 - game;

	var prevGame1 = game - gameNum;
	var prevGame2 = game - (gameNum + 1);

	if ((document.myForm.winner + game.value != document.myForm.winner + prevGame1.value) && (document.myForm.winner + game.value != document.myForm.winner + prevGame2.value)) {	
		alert("Teams don't match up.");
	} else {
		alert("Teams do match. Game: " + bracket + game);
	}

}
