Hi, I looked around in the group, but most of the topics are completely beyond my comprehension at this point.

All I want to do is load chance.js when the whole thing loads so that I can use some of its functions in html tiddlers.

I tried editing the whole file and putting in <script src="chance.js" /> in the head section near

<link id="faviconLink" rel="shortcut icon" href="favicon.ico">

which worked - until I had edited something and saved, and that line went away.

What's the right way to do this?

TIA

Pete

Put your <script...> call into a tiddler (any name), and tag that tiddler with $:/tags/RawMarkup

When the document is saved, it will automatically insert the content from tiddlers with that tag directly into the <head> of the document file, so that the script will be invoked the next time you reload.

As a side note, you should *never* have to hand-edit the TiddlyWiki source file to add functionality. Most of the time, there are already hooks and other mechanisms for adding customizations to the core code.

enjoy,

Thanks, Eric. More info: The tiddler I want to use chance from is a text/html type, with a form in it which shows up in an iframe. After following your directions, the <script.. code is now in the main <head> section of the TW, and it is no longer in the <head> section of the document inside the iframe. Nothing happens when I click a form input button that calls a chance function - not even an error in the console. Further suggestions?

Pete
