How to simulate click event for tinyMCE v6x custom toolbar button programmatically - tinymce

Question

This is simple enough in earlier version of tinyMCE, but I can't find a way to make it work in v6x (suggested answers here only apply to earlier versions, that I can see)
Here's my button:
tinymce.PluginManager.add('newButton', (editor, url) => {
editor.ui.registry.addButton('newButton', {
text: 'Click me',
enabled: true,
onAction: () => {
alert('You clicked me')
}
})
return {
getMetadata: () => ({
name: 'newButton',
url: ''
})
}
});
tinymce.init({
selector: "textarea",
plugins: "newButton",
toolbar1: "newButton"
});
This works fine - click the button and you get an alert telling you you have. What I want to do now is call this click event from code (JaveScript) - I was hoping
tinymce.activeEditor.buttons['newButton'].onclick();
would work, as it does for - say - the "code" plugin; i.e. add this plugin (and button) to the editor and calling
tinymce.activeEditor.buttons['code'].onclick();
simulates clicking the toolbar button. So... how can I "click" my own custon toolbar button?
[edit] well.. that last line did work, I swear it did. Now it doesn't. wt.. :(

Answer 1

This may not be the "right" way (well, I know it isn't!) but I've found a way that works :)
First, I need a way to identify/find my custom button. I figured out tinymce renders them as div elements, and using
var divs = document.querySelectorAll('button');
divs.forEach((div) => {
console.log(div.innerHTML);
})
I am able to identify it and find the HTML used - it is not graced with an id, but we can use the innerHTML property (as identified) to get it and then simulate a click- viz:
var divs = document.querySelectorAll('button');
divs.forEach((div) => {
// NB 'DOC' is the text property of my custom button
if (div.innerHTML === '<span class="tox-tbtn__select-label">DOC</span>') {
// now we can simulate a click on it:
var evt = new MouseEvent("click", {
view: window,
bubbles: true,
cancelable: true
});
div.dispatchEvent(evt);
return;
}
})
(Thanks to the second answer, by Derek, here:

for the simulate click code)
[edit] better to use a for-loop rather than forEach as there's no sensible way to break out of the latter - that "return" doesn't actually do anything.
