Basic Question about JavaScript

[Chems]

Hey,

how do I actually write JavaScripts in Tiddlywiki?

I thought I could just write the code into a tiddler, but it doenst work.

How does the basic structure look like, if for example I want to create a variable, assign a value and finally print that it is visible in the tiddler.

Thanks in advanced!

Hi,

If you want to define a variable in TW, there are different ways.

1) set-widget: https://tiddlywiki.com/#SetWidget

2) vars-widget: https://tiddlywiki.com/#VarsWidget

3) \define aMacro() : see Macros in wikitext

Variables have a scope. Try this eg:

\define aMacro()
just some text.
\end

<$set name="var1" value="VAR1">
  <<var1>> - <<aMacro>><br>
  <$set name="var1" value="xxx">
    <<var1>> - <<aMacro>>
  </$set>
</$set>

<$vars var-a="asdf" var-b="bbb">
<<var-a>> - <<var-b>>
</$vars>

Have fun!

The two main ways of using are javascript macros, and widgets. The documentation for Widgets is pretty poor/sparse. But javascript macros are easier:
