Code Title: Paging (modifiable)
Description: Add paging to your record retrieval. But, do it with the good'ol form field that allows you
to just type in directly what page ya wanna go to. This one is our fave! It even alternates the background
color (bgcolor) of each row, to make viewing the recordset even easier.. We use different tweaked versions
of this one all over our site! See an example of this code snippet on our International page.We have made it so that it will display a hyperlinked first item in one column, then a truncated
description using the Left() function in the next column. The hyperlink will take you to the specific
article or record, (whatever you're using it for).
We use a javascript valid number checker on this one, just to make sure the person doesn't enter any weird
characters into the page number field of the form. We don't normally do this, but if ya want the
javascript for number checking, check out our jsNumberValidator.
