Cannot able to get the selected text along with its formatted html

[suganyapalani22]

When selecting the text, i need to add the outer div with some format, I have used this code, but throws some exceptions,

const range = currentElement.summernote('createRange'); var newrange=range.nativeRange() const newParent = document.createElement('span'); newParent.setAttribute('contenteditable', false); newParent.setAttribute('class', 'freeze-word'); var newtext=newrange.surroundContents(newParent);

The exception, Failed to execute 'surroundContents' on 'Range': The Range has partially selected a non-Text node.
