I\'m using jQuery to edit the background-color of table cells. My code is as follows (the each cell has numbers in the format \"x/y\" so I mine them out at the star

Just as Jason P mentioned the following code should work fine :

        $(document).ready(function () {
            $("#overview td").each(function () {

                var content = $(this).html();
                var vals = content.split("/");
                var ratio = vals[0] / vals[1];
                alert(ratio);


                var red;
                var green;

                if (vals[1] == 0) {
                    $(this).css('background-color', '#00FF00');
                } else {
                    if (ratio > 0.5) {
                        red = 255;
                        green = parseInt(-2 * 255 * ratio + (2 * 255));
                    } else {
                        green = 255;
                        red = parseInt(2 * 255 * ratio);
                    }
                    var rgbColor = 'rgb(' + red + ',' + green + ', 0)';
                    var hexColor = rgb2hex(rgbColor);
                    $(this).css('background-color', hexColor);
                }
            });
        });

The .each method is just simply an iteration over the retrieved objects.
