Lab 15 Hand code a form

Before you do this lab, you must understand what is CGI(Common Gateway Interface)  and Form.

1. So please search the answer and post your opinion in your blog.
2. Hand code a HTML to edit an HTML so that the webpage can send a request to Google like
http://maps.google.com/maps?q=24.9586,+121.24114

Use Form CGI that includes action, input, and submit.
Try a few different coordinates.
3. If the input is not in the format of coordinates, display an error and ask the user to retry. For example, an incorrect input may look like 12.a2,21.22
