Passer Rating Calculator

The passer rating calculator was a personal project which I originally wrote in straight Javascript and then re-wrote using jQuery. The finished project, found at PasserRatingCalculator.com, is the jQuery version. The application allows a user to enter quarterback passing statistics and generate the passer rating based on the NFL’s own passer rating algorithm.

The application has validation such as requiring an Integer to be entered into the appropriate text boxes, making sure that completions aren’t greater than attempts, or touchdowns greater than completions or attempts. Error messages are output to the screen in red text and each text box is outlined with a red dashed border and highlighted with a lighter red background to indicate an error.
