HowToUseJavascriptOnload < Support

Question

I would like to use a JavaScript library in a TWiki topic. As far as I can see, to link a <script> in the <head> of the page, I would need to overwrite %TMPL:DEF{"head"}%. To use the <body onload="...">, I would need to overwrite %TMPL:DEF{"bodystart"}%.

I read about TWikiTemplates and I tried to make a file templates/Web.Topic.tmpl, using "Main" as Web and my topic as the Topic. It didn't work.

What is the best way to link a JavaScript library in the <head> of the page, and to use the <body onload="..."> function?

Answer

If you don't mind to add the few lines again after an upgrade, the easiest way would be to simply add your script to templates/twiki.tmpl.

What you have tried (and the link you've given) suggests that you followed the documentation for the previous TWiki version - TWiki.org is still running version 3. Check out the TWiki.TWikiTemplates topic in your own installation, or on twiki.org use TWikiTemplates as guidance for more "official" ways to customize templates.

Thanks a lot for your answer.

I searched the support web and found that if you don't want to overwrite templates/twiki.tmpl, you can copy the files

templates/view.pattern.tmpl
templates/twiki.pattern.tmpl

templates/view.myskin.tmpl
templates/twiki.myskin.tmpl

When you use the skin "myskin", then the new templates are used. A way to choose an other skin for a certain topic is described at TemplateOverridePerTopic.

P.S. I used this to include a Google Map in my Twiki. I will document my results at http://www.fstab.de/twiki/bin/view/Main/TWikiNotes

When you create a new skin, you can include javascript in TMPL:DEF templatejavascript. For instance in view.myskin.tmpl:

%TMPL:INCLUDE{"view.pattern"}%

%TMPL:DEF{"templatejavascript"}%
<script type="text/javascript">
//<![CDATA[
   addLoadEvent(setfocus);
   function setfocus() {
      document.loginform.username.focus();
   }
//]]>
</script>%TMPL:END%

The onload script above is an example from login.pattern.tmpl, and illustrates how to add a function that should be called at page onload.
