You should be able to use Tobias suggestion
<$set name="js-macro-link-text" value={{!!test}}>
<$button set=!!test setTo=<>>Test button
In your javascript macro you can read the value of "js-macro-link-text"
like so:
var input = this.getVariable("js-macro-link-text");
cheers

[tw] Re: [TW5] How to create a button that replaces a field value based on the current field value?
Hello,
What I've found so far is:
1) Macros and widgets may look something like javascript functions and
variables, but they often behave differently
2) You can't use a widget's output inside a widget
3) You can use a macro inside a widget IF it doesn't have a parameter
4) Therefore, you will most often need to use <$set ...> to set a variable
to be used by a macro that gets fed to your widget

Hi Antaeus,
One (perhaps) clumsy way to go about it would be
to not try and pass a ("text") *parameter* to your inner macro,
but rather set a *variable* outside of all that via the SetWidget,
so you could then do...
<$set name="js-macro-link-text" value={{!!test}}>
<$button set=!!test setTo=<>>Test button
Best wishes,
— tb

By the way, if macros with parameters don't work as widget attributes... does that mean that the last example shown for the MacroCall Widget doesn't actually work? >From http://tiddlywiki.com/#MacroCallWidget : <$macrocall $name="italicise" text=<>/> Does this not work, and it got included as an example without testing? Or, if it does work, why does it work when other attempts to use macros as attributes fail? -- You received this message because you are subscribed to the Google Groups "TiddlyWiki" group.

Apparently you can use static text. But this is of limited value IMO. What you want is something more like <> . I just know whenever I've tried making a bit of simple widget code work with some macros, I usually end up needing to use <$set>.

[tw] Re: [TW5] How to create a button that replaces a field value based on the current field value?
Tobias, Mark, thank you for your suggestions... The use of SetWidgets to set variables is something I didn't understand before, and I can tell I'll eventually be able to use it to achieve a much cleaner solution. Right now, though, I still have a problem that's completely blocking me: how do I get the *results* of a macro call into a variable? The project I'm working on will involve dates. I can write a macro in Javascript which takes a date in TW's format and adds or subtracts a given amount of time. But how can I have TiddlyWiki call that macro *and* store it in a field rather than simply rendering the result on the screen? -- You received this message because you are subscribed to the Google Groups "TiddlyWiki" group.
