APEXblog.nl - Tips and Tricks

About This Blog:
I (Richard Weug) started this blog primary for myself to save all kinds of Apex tips and tricks in one place. To use it as a place to write down how I used some coding in my own projects, but also to copy and paste all kinds of articles I find on the Internet. (So I never have to wonder on what website did I read about??? When I see something interesting I collect the content so I have my own archive/knowlegde base.

This is a nice demo I found quite some time ago (2010). Recently I looked for this demo, and could hardly find it, so I added it to my website.

Client-side form validation in APEX

Written by Richard Weug on Monday, 04 March 2013 14:11. Posted in Apex

Something that I really miss in APEX development is out-of-the-box support for client-side form validation. Most web applications these days make use of live validations written in JavaScript to instantly inform the end user on incorrect input. This greatly improves the usability and performance of your system since you avoid the user from submitting obvious erroneous data to the server. Don’t get me wrong; client-side validation is not a substitute for server-side validation. It’s simply too easy for an end user to bypass the JavaScript-driven validations.

Using websockets in APEX for automatic refresh

Written by Richard Weug on Thursday, 14 February 2013 14:41. Posted in Tips and Tricks

In my former post Using websockets in APEX for automatic refresh I explained how to implement a mechanism with an external websocketserver to push a refresh to an APEX page. It used Beaconpush. But I didn’t like the dependency on an external websocketserver (I’m just that way), so I investigated what it should take to implement my own websocketserver.
