JS help

Hello,

I don't know how JavaScript works, I can only work on HTML and CSS, hence I require some help with this particular JS.

We have a table where we rank people according to their wins/loss + points. In this table, each win is +1 point and each loss is -1 point (i think).

I believe this is the part that handles math in this code:

Code:

    function bubbleSort(a)
    {
        var swapped;
        do {
            swapped = false;
            for (var i=0; i < a.length-1; i++) {
                if (eval(a[i][5]) < eval(a[i+1][5])) {
                    var temp = a[i];
                    a[i] = a[i+1];
                    a[i+1] = temp;
                    swapped = true;
                }
            if (eval(a[i][5]) == eval(a[i+1][5])) {
                if (eval(a[i][3]) > eval(a[i+1][3])) {
                  var temp = a[i];
                  a[i] = a[i+1];
                  a[i+1] = temp;
                  swapped = true;
                }
                }
            }
        } while (swapped);
    }



I could be wrong tho.

Anyway, this is the page, if you want to take a look: http://www.duelacademy.net/h1-rankings

I'd like it to count each win as +3 points, and each loss as -1 point. There is Wins, Lose, Games Played, Points. I'm not sure how the code works exactly, but It uses your wins, loses and games played to do the math and distribute points.

I can't explain this any better lol

Thanks for your help

the way its calculated you would have to add 3 wins for every 1 win 

one of these should do the trick

Code:

    function bubbleSort(a)
    {
        var swapped;
        do {
            swapped = false;
            for (var i=0; i < a.length-1; i++) {
                if (eval(a[i][5]) < eval(a[i+3][5])) {
                    var temp = a[i];
                    a[i] = a[i+3];
                    a[i+3] = temp;
                    swapped = true;
                }
            if (eval(a[i][5]) == eval(a[i+1][5])) {
                if (eval(a[i][3]) > eval(a[i+1][3])) {
                  var temp = a[i];
                  a[i] = a[i+1];
                  a[i+1] = temp;
                  swapped = true;
                }
                }
            }
        } while (swapped);
    }


or

Code:

        function bubbleSort(a)
        {
            var swapped;
            do {
                swapped = false;
                for (var i=0; i < a.length-1; i++) {
                    if (eval(a[i][5]) < eval(a[i+1][5])) {
                        var temp = a[i];
                        a[i] = a[i+1];
                        a[i+1] = temp;
                        swapped = true;
                    }
                if (eval(a[i][5]) == eval(a[i+1][5])) {
                    if (eval(a[i][3]) > eval(a[i+3][3])) {
                      var temp = a[i];
                      a[i] = a[i+3];
                      a[i+3] = temp;
                      swapped = true;
                    }
                    }
                }
            } while (swapped);
        }
