Getting Started: Building Applications with RL-ARM
that consumes minimal bandwidth. The most commonly used browsers can take
this data and update the web page without having to reload the full page. This
gives flicker free “real-time” update of dynamic objects within the web page.
To see how the Ajax support works within RL-
TCPnet, we will look at creating a CGI page that
contains eight tick boxes that reflect the state of a
series of buttons connected to port pins on the
user hardware. The necessary Ajax JavaScript
support is contained in a support file called
xml_http.js
server project as shown above. Next, we must
create a CGI page,
eight check boxes. A separate XML file,
buttons.cgx
dynamic data as XML tags.

A refresh button, a tick box,
and eight status boxes are
created in a form that uses
the post method. The
refresh button will invoke a JavaScript function, updateMultiple(). Checking the
periodic tick box will call a separate JavaScript function, periodicUpdate().
