示例代码

以下示例代码使用该 API 的版本 1

创建新演示文稿

以下示例演示了如何使用 Google 幻灯片高级服务创建新的演示文稿。这相当于创建新的演示文稿食谱示例。

advanced/slides.gs
/**
 * Create a new presentation.
 * @return {string} presentation Id.
 * @see https://developers.google.com/slides/api/reference/rest/v1/presentations/create
 */
function createPresentation() {
  try {
    const presentation =
      Slides.Presentations.create({'title': 'MyNewPresentation'});
    console.log('Created presentation with ID: ' + presentation.presentationId);
    return presentation.presentationId;
  } catch (e) {
    // TODO (developer) - Handle exception
    console.log('Failed with error %s', e.message);
  }
}

创建新的幻灯片

以下示例演示了如何在演示文稿中使用预定义布局在特定索引处创建新幻灯片。这相当于创建新幻灯片食谱示例。

advanced/slides.gs
/**
 * Create a new slide.
 * @param {string} presentationId The presentation to add the slide to.
 * @return {Object} slide
 * @see https://developers.google.com/slides/api/reference/rest/v1/presentations/batchUpdate
 */
function createSlide(presentationId) {
  // You can specify the ID to use for the slide, as long as it's unique.
  const pageId = Utilities.getUuid();

  const requests = [{
    'createSlide': {
      'objectId': pageId,
      'insertionIndex': 1,
      'slideLayoutReference': {
        'predefinedLayout': 'TITLE_AND_TWO_COLUMNS'
      }
    }
  }];
  try {
    const slide =
      Slides.Presentations.batchUpdate({'requests': requests}, presentationId);
    console.log('Created Slide with ID: ' + slide.replies[0].createSlide.objectId);
    return slide;
  } catch (e) {
    // TODO (developer) - Handle Exception
    console.log('Failed with error %s', e.message);
  }
}

读取页面元素对象 ID

以下示例演示了如何使用字段掩码检索特定幻灯片上每个页面元素的对象 ID。这相当于从网页读取元素对象 ID 方案示例。

advanced/slides.gs
/**
 * Read page element IDs.
 * @param {string} presentationId The presentation to read from.
 * @param {string} pageId The page to read from.
 * @return {Object} response
 * @see https://developers.google.com/slides/api/reference/rest/v1/presentations.pages/get
 */
function readPageElementIds(presentationId, pageId) {
  // You can use a field mask to limit the data the API retrieves
  // in a get request, or what fields are updated in an batchUpdate.
  try {
    const response = Slides.Presentations.Pages.get(
        presentationId, pageId, {'fields': 'pageElements.objectId'});
    console.log(response);
    return response;
  } catch (e) {
    // TODO (developer) - Handle Exception
    console.log('Failed with error %s', e.message);
  }
}

添加新的文本框

以下示例演示了如何向幻灯片添加新的文本框并向其中添加文本。这相当于向幻灯片添加文本框的制作说明示例。

advanced/slides.gs
/**
 * Add a new text box with text to a page.
 * @param {string} presentationId The presentation ID.
 * @param {string} pageId The page ID.
 * @return {Object} response
 * @see https://developers.google.com/slides/api/reference/rest/v1/presentations/batchUpdate
 */
function addTextBox(presentationId, pageId) {
  // You can specify the ID to use for elements you create,
  // as long as the ID is unique.
  const pageElementId = Utilities.getUuid();

  const requests = [{
    'createShape': {
      'objectId': pageElementId,
      'shapeType': 'TEXT_BOX',
      'elementProperties': {
        'pageObjectId': pageId,
        'size': {
          'width': {
            'magnitude': 150,
            'unit': 'PT'
          },
          'height': {
            'magnitude': 50,
            'unit': 'PT'
          }
        },
        'transform': {
          'scaleX': 1,
          'scaleY': 1,
          'translateX': 200,
          'translateY': 100,
          'unit': 'PT'
        }
      }
    }
  }, {
    'insertText': {
      'objectId': pageElementId,
      'text': 'My Added Text Box',
      'insertionIndex': 0
    }
  }];
  try {
    const response =
      Slides.Presentations.batchUpdate({'requests': requests}, presentationId);
    console.log('Created Textbox with ID: ' +
      response.replies[0].createShape.objectId);
    return response;
  } catch (e) {
    // TODO (developer) - Handle Exception
    console.log('Failed with error %s', e.message);
  }
}

设置形状内文字的格式

以下示例演示了如何设置形状文本的格式,包括更新文本的颜色、字体和下划线。这相当于设置形状或文本框中的文本格式的操作方法示例。

advanced/slides.gs
/**
 * Format the text in a shape.
 * @param {string} presentationId The presentation ID.
 * @param {string} shapeId The shape ID.
 * @return {Object} replies
 * @see https://developers.google.com/slides/api/reference/rest/v1/presentations/batchUpdate
 */
function formatShapeText(presentationId, shapeId) {
  const requests = [{
    'updateTextStyle': {
      'objectId': shapeId,
      'fields': 'foregroundColor,bold,italic,fontFamily,fontSize,underline',
      'style': {
        'foregroundColor': {
          'opaqueColor': {
            'themeColor': 'ACCENT5'
          }
        },
        'bold': true,
        'italic': true,
        'underline': true,
        'fontFamily': 'Corsiva',
        'fontSize': {
          'magnitude': 18,
          'unit': 'PT'
        }
      },
      'textRange': {
        'type': 'ALL'
      }
    }
  }];
  try {
    const response =
      Slides.Presentations.batchUpdate({'requests': requests}, presentationId);
    return response.replies;
  } catch (e) {
    // TODO (developer) - Handle Exception
    console.log('Failed with error %s', e.message);
  }
}

最佳做法

批量更新

使用 Google 幻灯片高级服务时,请在数组中组合多个请求,而不是在循环中调用 batchUpdate

- 在循环中调用 batchUpdate

var titles = ["slide 1", "slide 2"];
for (var i = 0; i < titles.length; i++) {
  Slides.Presentations.batchUpdate(preso, {
    requests: [{
      createSlide: ...
    }]
  });
}

执行 - 使用更新数组调用 batchUpdate

var requests = [];
var titles = ["slide 1", "slide 2"];
for (var i = 0; i < titles.length; i++) {
  requests.push({ createSlide: ... });
}

Slides.Presentations.batchUpdate(preso, {
  requests: requests
});
