How to send message using checkbox widget?

[LinOnetwo]

I try to use following checkbox, I want the state be sync to my plugin.

<$checkbox checkactions="checkUseServerStoryList" uncheckactions="unCheckUseServerStoryList" >

 <$action-sendmessage $name="checkUseServerStoryList" $message="tm-solid-useServerStoryList" />

 <$action-sendmessage $name="unCheckUseServerStoryList" $message="tm-solid-notUseServerStoryList" />

 <<lingo UseServerStoryList>>

</$checkbox>

In my plugin I receive that message:

    // sync config to here

   $tw.rootWidget.addEventListener('tm-solid-useServerStoryList', () => {

     this.useServerStoryList = true;

     console.log(this.useServerStoryList);

     

   });

   $tw.rootWidget.addEventListener('tm-solid-notUseServerStoryList', () => {

     this.useServerStoryList = false;

     console.log(this.useServerStoryList);

   });

在此输入代码...

But nothing is log out, that is why?

That is not the correct way to invoke actions from widgets.  $action-sendmessage widget does not recognize or use a $name parameter.

Rather, you must use the "\define" syntax to declare the actions as macros to give them names.  Place the following at the start of the tiddler:

\define checkUseServerStoryList()
   <$action-sendmessage $message="tm-solid-useServerStoryList" />
\end

\define uncheckUserServerStoryList()
   <$action-sendmessage $message="tm-solid-notUseServerStoryList" />
\end

Then, in your checkbox widget, you would write:

<$checkbox checkactions=<<checkUseServerStoryList>> uncheckactions=<<unCheckUseServerStoryList>

> >
  <<lingo UseServerStoryList>>
</$checkbox>

Alternatively, if you prefer to have the checkbox AND actions written together, you can forego the use of names altogether, and place the actions in-line, within the checkbox syntax, like this:

<$checkbox
    checkactions="""<$action-sendmessage $message="tm-solid-useServerStoryList"    />"""
  uncheckactions="""<$action-sendmessage $message="tm-solid-notUseServerStoryList" />""" >
  <<lingo UseServerStoryList>>
</$checkbox>

Note that, because the action-sendmessage widget uses double-quotes around the $message parameter, you must use TRIPLED double-quotes surrounding the checkactions and uncheckactions parameters of the checkbox widget.

The first syntax (using \define) is recommended.

That should do it.   Let me know how it goes...

enjoy,

That works, Thank you, Eric!

And I chage to dash saparated variable, to fit wikitext:

\define check-use-server-story-list()

 <$action-sendmessage $message="tm-solid-use-server-story-list" />

\end

\define uncheck-use-server-story-list()

 <$action-sendmessage $message="tm-solid-not-use-server-story-list" />

\end

<$checkbox field="use-server-story-list" checked="yes" unchecked="no" default="yes" checkactions=<<check-use-server-story-list>> uncheckactions=<<uncheck-use-server-story-list>> >

<<lingo UseServerStoryList>>

</$checkbox>

And I change to dash separated variable, to fit wikitext:

I generally use mixed-case naming for variables and macro names, so that they don't look like message IDs.

Though in this particular case, since the macros are basically wrappers around $send-message calls,

it may be appropriate to use dash-separated naming as you have done.
