Hello,
I have a macro definition that invokes a widget that I'm developing. The
default value of the tokens parameter is the empty string. This is the
macro definition
\define codereveal( tokens:"" )
<$reveal type="match" state=<<qualify "$:/status/$(currentTiddler)$">>
text="open">
<$codeLine language="ipx" code={{!!text}} tokens=$tokens$/>
</$reveal>
\end
Then I'm getting that value in the widget like this:
this.userTokens = this.getAttribute("tokens") || undefined;
console.log(this.userTokens);
But instead of getting what I expect ("" || undefined = undefined ),
undefined for empty string ("") im getting true. Why?
thanks tgo all
