There are many occasions when one needs to add some javascript that requires something like

<body onLoad="dosomething">
(even some of the TWiki templates have an onLoad="initForm()" in the body tag.

I suggest to add a function akin to TWiki::addToHEAD that let's one collect up material to stuff into the onLoad attribute of the body tag.

I've got the code written, but before I update all the templates, I'd prefer some feedback.

How about using a preferences variable instead? This gives TWiki applications the opportunity to manipulate the body tag. Such as a BODYTAGATTR setting in TWikiPreferences, initialized to an empty value. All skins would have somehing like <body class="patternViewPage" %BODYTAGATTR%>

-- PTh

Be careful with body onload handlers. Because many parts of a TWiki page want to have control over the onload (multiple plugins, the skin), we now use this method:

<script type="text/javascript">
//<![CDATA[
   addLoadEvent(myFunc);
   function myFunc () {
      // initializing code
   }
//]]>
</script>

AC, great advice. Works neat and does not require any new feature for TWiki. Thanks. -- TW
