适用于PowerPoint的Office.js应用编程接口(预览)

Question

我正在尝试使用新的Powerpoint的Office.js应用程序接口，它目前还处于预览阶段。我无法使用PowerPoint.run()方法调用任何东西，因为它的行为似乎与Excel和Word中的不同。有人能帮我找到一种可行的方法来调用这里引用的SlideCollection.getCount()方法吗？

https://docs.microsoft.com/en-us/javascript/api/powerpoint/powerpoint.slidecollection?view=powerpoint-js-preview

示例代码(假设我需要在尝试获取计数之前先加载项)：

PowerPoint.run(function (context) {
  var properties = context.presentation.slides.items;
  context.load(properties);
  return context.sync()
    .then(function() {
      console.log(properties);
    })
    .catch((error) => console.log(error));
})

Answer 1

下面是对slides.getCount()的调用，它应该可以工作

PowerPoint.run(async (context) => {
    context.presentation.load("slides");
    await context.sync();

    var slides = context.presentation.slides;
    var slideCount = slides.getCount();
    await context.sync();

    console.log("There are ", slideCount.value, " slides in this presentation");
}

Answer 2

PowerPoint.run(async function (context) {
  context.presentation.load("slides");
  await context.sync();
  const slide = context.presentation.slides.getItemAt(0);
  slide.load("id");//you just load any property from PPT object model and then sync
  await context.sync();
  console.log(slide.id);
});
