I want to program the same functionality from Insert>Bookmark on Google Docs. I already used the addBookmark(cursor), now I want to do it on a selected text/image. See screenshot for reference ("congue" is the selected word).

CodePudding user response：

You can add a bookmark at the selection using this as an example.

function addBookmark() {
  try {
    let doc = DocumentApp.getActiveDocument();
    let selection = doc.getSelection();
    if( selection ) {
      let elements = selection.getRangeElements();
      let element = elements[0];
      let position = element.getStartOffset();
      position = doc.newPosition(element.getElement(),position);
      doc.addBookmark(position);
    }
  }
  catch(err) {
    console.log(err);
  }
}

Reference

• Document.getSelection()
• Selection.getRangeElements()
• RangeElement.getElement()
