Re: standard ajax or jquery functions for browser data entry

Well lets break it down by what your customers would like to see....

Google style autocomplete - This can be done, as mentioned, with jQuery
UI. It is extremely stable code that is used by many prominant companies
as well as tons of smaller projects as well.

Popup Calendars - Once again, jQuery UI covers this.

Edit Fields While Typing - ??? Not sure what you mean? Do you mean only
allowing Numerics in numeric fields? If so, I have written a javascript
function that does just what you want.

Dynamic Drop Downs - This is really very similar to autocomplete, except
you put the results into another combo box instead of a list box under
your entry box. Also, this requires only 1 ajax request when the user
makes a selection. Can be done with jQuery, any other framework, or
unfiltered JavaScript (if you wish).

These are all fairly standard and commonly implemented form features. That
is why your customers are requesting them, they've seen them and like
them. A great way to get started is by searching for jQuery Form
Validation. This will give you lots of examples and resources to look at
to get a jump on what you need. This link in particular is a great place
to start...

What other things do you want to discuss about Web2.0 development?

[WEB400] standard ajax or jquery functions for browser data entry






I am preparing to update a browser based order app, written in rpg cgi 10
years ago. A lot has changed in user editing capabilities over those
years. To piggyback on recent discussions on rpg'rs coding modern web2.0
type app, what are the functions most used that one needs to incorporate,
and if possible - where are the working examples? I've been astounded (not
really.) by the code examples on many sites/forums that just plain don't
work. One (while trying to implement autocomplete function) in a well
reviewed book had just plain bad syntax in the examples.
My emphasis is logical and efficient data entry, NOT pretty presentations,
bouncing balls & flash video.
Users are asking for that "google" entry effect "autocomplete", popup
calendars, edit fields while typing, and dynamic dropdown menus to get to
anywhere.
Since customers in this as well, must include last x years of various
browsers.
Over the years on midrange-l we've had lots of discussion of DDS functions
- let's have one on web2.0 interface.
