composer.addButton add always button
-
I need to add a button in my formatting bar and I use in my file.js this:
require(['composer', 'composer/controls'], function(composer, controls) { composer.addButton('fa fa-calendar', function(textarea, selectionStart, selectionEnd) { if (selectionStart === selectionEnd) { } }); });The problem is that when I add one time the "fa fa-calendar" it is work but when I recreate the formatting bar the code adds me another button with "fa fa-calendar" so I have two button with "fa fa-calendar". Anyone can help me?

That code should only ever run once. You just need to move this code out of whatever code you're running when the formatting bar is created.

@yariplus I have another question. This code is execute one time when the first page is loaded and attach the button to "edit form". My problem is that I want see the button only if the topic respect some specifics. So I would remove the button because the button it can't forever be seen . can you suggest something? Maybe with some method of composer?

During
action:composer.loaded, hide the button with css using the passed in post_uuid.$('#cmp-uuid-' + post_uuid + ' .your-buttons-class').hide()You should be checking the condition in the button callback, so even if the user manually unhides the button, it won't do anything.
