14728Forms and Frameshttp://idm.internet.com/idm/vol2/18/clientcorner.htmlThe most effective way to understand JavaScript's power is to apply it to forms. JavaScript lets your visitors complete your forms faster than using CGI (Common Gateway Interface). One of the problems with CGI is that when a user makes a mistake filling out a form, he or she has to wait for the server to return an error message. With JavaScript, this process is almost instantaneous. You can set up the form so that when the user clicks on the submit button, JavaScript will check to see if all the input is valid before it sends it to you or your server.JavaScript > Tips and Tutorials > FormsOct 12, 2006
A few weeks ago, I started a simple tutorial on how to cascade JavaScript check boxes from one row to the next in order to simplify the manipulation of large forms. This week, I’ll take it a step further by adding the same ability to both drop downs and text fields.
Move items from one menu to another by using two multiple-select menus. Make it easy to create a list, for example. I found this useful when creating a distribution list where I had a set of people available on one side and the list on the other.
I ran accross this code when working on a registration product site. The goal is to save the user's time by not having them fill in the same address over and over, if the address for there billing is the same as the mailing address.
