scripts in html vs. web help

[arqwe]

I inserted a javascript into a topic in an attempt to create tabs that change the text in a sub-window rather than linking to an entirely new page. My tabs work in the web help, but are not displayed in the chm. Are some scripts not supported in HTML help? TIA.

Hi,

The short answer: Regular JavaScript is supported, but there are limitations.

This is because of two things: CHM uses the IE engine to render the pages. This means that the limitations of IE are also the limitations of your CHM. This includes problems with CSS and, sometimes, scripts.

Also, when you use RoboHelp 8, the webhelp uses the XHTML 1.0 transitional standard. This forces IE in a strict rendering mode. In the CHM, the pages use the HTML 4.01 frameset standard, putting IE in a different rendering mode (IE 5.5). This means that your scripts have to be compatible with a IE 5.5 rendering mode.

If you change your script so it will work with CHM, it should also work for WebHelp.

Greet,

Willam
