Try this (untested) code that "hijacks" the onClickTab() event handler to
add a little "fixup" code:
---------------------------------------------
// if the default TWCore function isn't saved yet, do it now.
if (!config.macros.tabs.orig_onClickTab)
config.macros.tabs.orig_onClickTab=config.macros.tabs.onClickTab;
// add fixup handling to correct for missing tiddler name in tab source
reference
config.macros.tabs.onClickTab = function(e)
{
// get the source reference for this tab
var content=this.getAttribute("content");
// if it starts with "##"
if (content.startsWith(config.textPrimitives.sectionSeparator) {
// get the name of the tiddler being viewed
var tid=story.findContainingTiddler(e).getAttribute("tiddler");
// add the tiddler name to the source reference for this tab
this.setAttribute("content",tid+content);
}
// allow the normal core tab handling to occur
return config.macros.tabs.orig_onClickTab.apply(this,arguments);
};
---------------------------------------------
Put the above code in a tiddler tagged with "systemConfig" (i.e., make it a
plugin) and the save-and-reload. To use, just write:
<<tabs txtMyTabs "first tab" "tab1" [[##Tab 1's Contents]] "second tab"
"tab2" [[##Tab2's Contents]]>>/%
!Tab 1's Contents
this is stuff in tab one
!Tab 2's Contents
this is stuff in tab two
!end
%/
enjoy,
