Google App Script Page break at cursor?

问题

I have a button in my sidebar of which's purpose is to insert a page break where the cursor is. I tried scripting it to just insert a page break (not at the cursor but just in the body) and it works fine.

However, I can't seem to get it to work at the cursor:

function pageBreak() {
var cursor = DocumentApp.getActiveDocument().getOffset();
insertPageBreak(cursor);
}

How can I accomplish this?

回答1:

You need to know the element type at the cursor position. Not all element types allow a page break to be inserted.

Begin by getting the element at the cursor position, then work from there.

function insertPgBrk() {
  var theCursor = DocumentApp.getActiveDocument().getCursor();
  var theElement = theCursor.getElement();
  var elementTypeAtCursor = theElement.getType();
  Logger.log('elementTypeAtCursor: ' + elementTypeAtCursor);

  if (elementTypeAtCursor === DocumentApp.ElementType.PARAGRAPH) {
    Logger.log('its the right type');
    theElement.insertPageBreak(0);
  };
};

You can't insert a page break in a TEXT element. The element needs to be a PARAGRAPH or a LISTITEM.
