Sorting Array

Posted 22 January 2012 - 12:30 PM

Hi,

Hope someone can help. I have created multiple arrays in JS as follows;

var tOne= new Array(0,"team one");
var tTwo= new Array(0,"team two");
var tThree= new Array(0,"team three");


I then have a function that gives the first element in the array a number ranking.
I want to create a table that ranks teams by the highest rank at the top.
To do this I want to rank by the first element in the array..

function sortNumber(a,B)
{
return a - b;
}

var n = [tOne[0],tOne[0],tOne[0]];
document.write(n.sort(sortNumber));


which seems to work.. however, I need a way to specify which team gets which rank. To give it an ID in effect.

Does anyone have any ideas?

You don't show how the rankings will be changed
but you should be able to adapt this to your needs.
<html>
<head>
<title> Untitled </title>
<script type="text/javascript">
// From: 

var tOne= new Array(0,"team one");
var tTwo= new Array(0,"team two");
var tThree= new Array(0,"team three");

// for testing purposes, set ranking
tOne[0] = 3;  tTwo[0] = 2;  tThree[0] = 1;

// get current ranking
var teamInfo = [tOne,tTwo,tThree];
var ranking = [];
for (var i=0; i<teamInfo.length; i++) {
  ranking.push(teamInfo[i][0]+':'+teamInfo[i][1]);
}
ranking = ranking.sort();
alert(ranking.join('\n'));

</script>

<style type="text/css">

</style>
</head>
<body>

</body>
</html>
