    Javascript contest help!


    I am trying to create a contest using javascript where people can enter a code that they receive at an event. Only so many of the codes are winners. The winners are directed towards a page where they can enter in their contact information, the others are directed towards a page that says thank you try again.

    Can anyone help?

    This is hopelessly insecure - like a Javascript password. The problem is that anyone can see the winning codes (those which redirect to a page where the user enters his contact information) simply with View Source.

    You need to use server-side scripting here unless you want a surprisingly high number of winners!

    All the code given in this post has been tested and is intended to address the question asked.
    Unless stated otherwise it is not just a demonstration.
