Google App脚本页面在光标处中断? [英] Google App Script Page break at cursor?

问题描述

我的侧栏中有一个按钮，其目的是在光标所在的位置插入一个分页符.我尝试编写脚本以仅插入一个分页符(不是在光标处，而是在正文中)，并且效果很好.

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.

但是，我似乎无法使它正常工作:

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

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

我该怎么做?

推荐答案

您需要知道光标位置的元素类型.并非所有元素类型都允许插入分页符.

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

首先将元素放在光标位置，然后从那里开始工作.

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);
  };
};

您不能在TEXT元素中插入分页符.元素必须为PARAGRAPH或LISTITEM.

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