How To Remove Tinymce Editor Buttons From Javascript?

I am using TinyMCE4.3.10 (as part of Wordpress 4.5.4). I create a custom tinymce editor using the code: tinyMCE.execCommand('mceAddEditor', false, captionId); tinyMCE.execCommand(

Solution 1:

You use tinymce.init({}) to invoke the editor with specific settings. If the ID of the <textarea> in question is contained in the variable captionId I would do this:

tinymce.init({
  selector: "#" + captionId,  //needs to be a string of the CSS selector for the ID
  .
  . 
  .
});  

This will target only that <textarea> for initialization. If you want to limit what options appear on the toolbar you can do so with the toolbar configuration option:

tinymce.init({
  selector: "#" + captionId,
  toolbar: [
    "table | insertfile undo redo | styleselect | bold italic",
    "removeformat | fontsizeselect | forecolor backcolor"a11ycheck
  ],
  . 
  .
});
