Need help for Lottery picker script

**Jy2m** · 04-22-2018, 11:53 AM

Hi,

About the script "Lottery Picker" anyone to tell me what I must change to obtain next number Y always superior to X + 1 (Y > X + 1)

Thanks.

Jy2m.

Could you be clearer about that please? There is no Y. And X never represents just one number.

Of course it isn't X an Y but, to explain me, imagine a draw like that :

7 15 21 22 43 55

the problem is that the fourth result (22) is equal to the third (21) +1 and I don't want it
I want that each number be at least equal to the preedent + 2.
In my example the fourth result would be for instance 23 or more.
So the question is : how modify he script to obtain this result?
Thanks.
Jy2m.

Since this is essentially the current version of:

http://www.dynamicdrive.com/dynamicindex12/lottery.htm

Please stop attaching it to your posts.

That said, I'm pretty sure this can be done. I'll let you know.

OK, this seems to do the trick (NOTE: do not copy code from a message the forum might send you, it could be corrupted, rather log on and copy from the post).

Code:

<!DOCTYPE html>
<html>
<head>
<title></title>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<style type="text/css">
.a1{
position:relative;
font-family:Verdana;
font-size:20px;
color:#888888;
}
</style>

<script>

var totalnumbers=10 //input total numbers to generate

var upperbound=70  //input upper bound for each random number

function lotto(){
var B=' ', LottoNumbers=[], RandomNumber, i, j, X, OutPut;	
 for (i = 1; i <= totalnumbers; i++)
 {
 RandomNumber = Math.round(lowerbound+Math.random()*(upperbound-lowerbound));
  for (j = 1; j <= totalnumbers; j)
  {
  if (RandomNumber == LottoNumbers[j])
    {
     RandomNumber=Math.round(lowerbound+Math.random()*(upperbound-lowerbound));
     j=0;
    }
  j++;
  }
 LottoNumbers[i]=RandomNumber;
 }
LottoNumbers=LottoNumbers.toString();
X=LottoNumbers.split(',');
 for (i=0; i < X.length; i++)
 {
 X[i]=X[i]+' ';
 if (X[i].length==2) 
 X[i]='0'+X[i];
 } 
X=X.sort();
 for (i=0; i < X.length; i++)
 {
 if(i && X[i - 1] == X[i] - 1) {X[i] = +X[i] + 1 + ' ';if (X[i].length==2)X[i]='0'+X[i];}
 if(i && X[i - 1] == X[i]) {X[i] = +X[i] + 2 + ' ';if (X[i].length==2)X[i]='0'+X[i];}
 OutPut=B+=X[i];
 }

document.getElementById("layer1").innerHTML=OutPut;

  lotto.T=setTimeout(lotto,20);
//window.status=OutPut;
}
function StOp(){
setTimeout(function(){clearTimeout(lotto.T);},1000);
}
</script>
</head>
<body>
<table border='0' width=350 height=50>
<tr valign='middle'>
<td align='center'>
<form name=form>
<input type=button value='Lottery Number Picker' onClick="lotto();StOp()">
</form>
<span id=layer1 class=a1>Result</span>
</td>
</tr>
</table>
</body>
</html>

Any questions or problems, just let me know.

It just occurred to me that if the second to last number is the upperbound - 1, this would force the last number to be upperbound + 1. It would be tough to get that out of the code. But you could always just make upperbound 1 less than the actual upper limit. Then it would be fine, except that number (the true upperbound) would then be less likely to occur.

Here's an even better solution (NOTE: do not copy code from a message the forum might send you, it could be corrupted, rather log on and copy from the post).

Code:

<!DOCTYPE html>
<html>
<head>
<title></title>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<style type="text/css">
.a1{
position:relative;
font-family:Verdana;
font-size:20px;
color:#888888;
}
</style>

<script>
'use strict';
if(![].indexOf){ // for IE 8 and less
	Array.prototype.indexOf = function(v, i){
		var l = this.length;
		if(typeof i === 'number'){if(i < 0){i = l + i;}} else {i = 0;}
		--i;
		while(++i < l){if(v === this[i]){return i;}}
		return -1;
	}
}

This version does not have the problem of going out of range.

Bravo, it works very well. Thank you very much. May I ask you one last question? I was used to the javascript version (attached) with which the digits from 1 to 9 were written 1 2 3 4 5 6 8 9 and not 01 02 03 04 05 06 07 08 09. Is this possible with your modified version?
Thanks.
