TinyMCE - How to add a button that wraps selected text with a tag

Question

I\'m currently using TinyMCE and would like to add a custom button that works as follows:

1. User highlights text in the text-editior
2. User clicks the custom

Answer 1

A better way to achieve this is to (1) perform a quick check to make sure the selection isn't empty, then (2) use the execCommand() method.

Using execCommand() means the action will be available to undo. @Warrior's answer uses setContent() which will not be undoable.

ed.addButton('mybutton', {
  title: 'My button', 
  class: 'MyCoolBtn', 
  image: 'MyCoolBtn.png', 
  onclick: function() { 
    ed.focus();
    var text = ed.selection.getContent({'format': 'html'});
    if(text && text.length > 0) {
      ed.execCommand('mceInsertContent', false, ''+text+'');
    }
  }
});
