Trumbowyg：在插入符号处插入文本不起作用

Question

I have a button and when clicking on it I want to add some text inside the Editor.

I saw some issues where people gave the solution and I tried it. But when I use restoreRange and execCmd with insertHTML , it does not insert at the caret, only if something is input in the editor before, like a character or a space.

In other words, when clicking on the editor, it does not insert where the caret was when I clicked, but when writing something, it does.

Like if restoreRange only worked when writing something.

The problem happens with the following code:

$('#editor').trumbowyg({
  btnsDef: {
    testButton: {
      fn: function () {
        // Restore the previous position
        $("#editor").trumbowyg('restoreRange');
        // Add text in the current position 
        $("#editor").trumbowyg('execCmd',
        {
          cmd: 'insertHTML',
          param: 'Dummy text',
          forceCss: false
        });
      },
      title: 'test button',
      text: 'insert text',
      hasIcon: false
    }  
  },
  btns: [
    ['testButton'],
  ]
});

Am I missing something?

Found the solution: save the range on blur and on focus.

$('#editor').trumbowyg({
btnsDef: {
  testButton: {
    fn: function () {
      $("#editor").trumbowyg('restoreRange');
      $("#editor").trumbowyg('execCmd',
        {
      cmd: 'insertHTML',
          param: 'Dummy text',
          forceCss: false
        });
      },
      title: 'Button tooltip',
      text: 'Displayed button name',
      hasIcon: false
    }
  },
  btns: [
    ['testButton'],
  ]
}).on('tbwblur', function(){
  $("#editor").trumbowyg('saveRange');
}).on('tbwfocus', function(){
  $("#editor").trumbowyg('saveRange');
});

Hope it helps someone!
