Adding Dynamic Content 249

Attaching HTML code

In WebPlus, you can create pages in HTML (see Creating HTML pages on

247). However, WebPlus also lets you attach code to your WebPlus objects

(e.g., in frames or table cells) and pages, primarily to expand the capabilities of

the objects (or the page), making them more intelligent and interactive. The

object or page can either dynamically generate content or can have its

appearance altered within its area as a result of embedded script content.

It's not possible to edit the HTML code itself (there's no real benefit in doing

so), but specific areas of the displayed code are editable for additional code to

be added, i.e. clearly identifiable placeholders (text surrounded by a white

highlight) will appear in your source tab's window.

These are just a few of the editable placeholders present in the source of an

HTML fragment, object or page (in fact differently named placeholders exist

depending on the type of element). For example, the last placeholder shown in

the list above is unique to a page's source and won't appear for an object or

HTML fragment.

Any code can be inserted by cut and paste into any of the placeholder

positions but typically you can include

tokens, HTML code or specific scripts,

e.g. JavaScript. This could be used to affect rollover behaviour on an object

not otherwise possible without scripting support, e.g. an image "on-click"

handler.
