Im new at programming and I need a little help
What Im try to do is
1. To create an HTML file that can validate forms WITHOUT the use a server. (is this possible?)
2. The validation of forms will be like the ones from registering a Yahoo email account (When you focus on another textbox there is an alert on the side of the textbox if it has an invalid value) - What do I need to study to do this without using a server?
Basically what I want is an html page that checks if the textbox has any values in it. If it doesnt have any, it will display an alert without the use of a new window. (Just like the registration page here)
Thank you in advance.
