Apps Script - Bookmark a Date Element on Google Docs-CodePudding

In general, I want to recreate the Insert>Bookmark on Google docs with a custom function upon bookmarking an element (all types of elements).

Now my issue is on bookmarking the Date element. I am getting

TypeError: Cannot read property 'getRangeElements' of null

My current code for bookmarking Date element was something like this


selection.getRangeElements().forEach(e => {
  const elmnt = e.getElement();
  const type = elmnt.getType();

  if( type == DocumentApp.ElementType.DATE ){
    bookmarked = doc.addBookmark( doc.newPosition(elmnt.asDate().getParent(), 1) )
  }

}); ```

CodePudding user response：

Modification points:

When I saw your showing script and your error message of TypeError: Cannot read property 'getRangeElements' of null, if selection is DocumentApp.getActiveDocument().getSelection(), I'm worried that you might have run the script without selecting the smart chip of Date. Please confirm this again.
And, in your script, ele is not declared. So, even when the error of TypeError: Cannot read property 'getRangeElements' of null was resolved, an error occurs at const type = ele.getType();.

When these points are reflected in your script, it becomes as follows.

Modified script:

When you run this script, please select the smart chip of Date and run the script. By this, the smart chip of Date is added as the bookmark.

function myFunction() {
  const doc = DocumentApp.getActiveDocument();
  const selection = doc.getSelection();
  selection.getRangeElements().forEach(e => {
    const ele = e.getElement();
    const type = ele.getType();
    if (type == DocumentApp.ElementType.DATE) {
      bookmarked = doc.addBookmark(doc.newPosition(ele.asDate().getParent(), 1));
    }
  });
}
