Overweight Calculator Installation (HTML/Javascript Version)

Installing this version is as easy as uploading the file on your web host. It just works. But you may want to include it as a part of existing web page. This is also easy, just follow these steps (Basic knowledge of HTML is required):

  1. Copy the javascript from the header to your new page
  2. Copy the HTML code of the calculator surrounded by comments
  3. Copy the last javascript function call that is under the BMI calculator. Alternatively you can call this function as body's onload attribute.

You can customize the messages that the script gives or its design by modifying the file in a text editor. Look at the beginning of the script, it should be pretty easy to find them.

This script is completely free and you can do everything you want in it. There are no obligations at all. There is a link to this page at the bottom, but if you wish to remove it, that's ok (We will appreciate if you leave it there though).
