Javascript 谷歌应用脚本：如何在谷歌幻灯片上创建幻灯片，并用数组中的信息填充其中的占位符？

我有一个数组，正在尝试使用其中的信息创建一个谷歌幻灯片演示文稿。我想得到一些帮助，如果可能的话，还可以给我指一些我可以阅读的材料，以便更好地理解这些问题的可能解决方案

阵列如下所示：

var myArray = [[Project1,Status1,Info1],[Project2,Status2,Info2],...,[ProjectN,StatusN,InfoN]]

function CreatingSlides() {

var displayName = "NEW LAYOUT"; // Name of the layout that I created
var presentationId = SlidesApp.openById(PageId).getId(); //It is an existing presentation, so I just get its ID
var layouts = Slides.Presentations.get(presentationId).layouts;
var layout = {};

//The following is the array of elements. In this example,
//I only used 4 projects, but it may vary and may not be
//a multiple of 4.
var myArray = [["Project1","Status1","Info1"],["Project2","Status2","Info2"],["Project3","Status3","Info3"],["Project4","Status4","Info4"]];


//This loop searches for the layout that I created
for (i in layouts) {
  layout[layouts[i].layoutProperties.displayName] = layouts[i].objectId;
  }

//In the slide created, this loop will fill the information in it using the myArray
for (i in myArray) {
  var resource = {"requests": [{"createSlide": {"slideLayoutReference": {"layoutId": layout[displayName]},
                                                "placeholderIdMappings": [{"layoutPlaceholder": {"type": "SUBTITLE","index": 0},"objectId":myArray[i][1],},],
                                                "placeholderIdMappings": [{"layoutPlaceholder": {"type": "BODY","index": 0},"objectId":myArray[i][2],},],
                                                "placeholderIdMappings": [{"layoutPlaceholder": {"type": "BODY","index": 1},"objectId":myArray[i][3],},],
                                                "placeholderIdMappings": [{"layoutPlaceholder": {"type": "SUBTITLE","index": 1},"objectId":myArray[i+1][1],},],
                                                "placeholderIdMappings": [{"layoutPlaceholder": {"type": "BODY","index": 2},"objectId":myArray[i+1][2],},],
                                                "placeholderIdMappings": [{"layoutPlaceholder": {"type": "BODY","index": 3},"objectId":myArray[i+1][3],},],
                                                "placeholderIdMappings": [{"layoutPlaceholder": {"type": "SUBTITLE","index": 2},"objectId":myArray[i+2][1],},],
                                                "placeholderIdMappings": [{"layoutPlaceholder": {"type": "BODY","index": 4},"objectId":myArray[i+2][2],},],
                                                "placeholderIdMappings": [{"layoutPlaceholder": {"type": "BODY","index": 5},"objectId":myArray[i+2][3],},],
                                                "placeholderIdMappings": [{"layoutPlaceholder": {"type": "SUBTITLE","index": 3},"objectId":myArray[i+3][1],},],
                                                "placeholderIdMappings": [{"layoutPlaceholder": {"type": "BODY","index": 6},"objectId":myArray[i+3][2],},],
                                                "placeholderIdMappings": [{"layoutPlaceholder": {"type": "BODY","index": 7},"objectId":myArray[i+3][3],},],
                                                }
                                },
                 {"insertText": {"objectId": myArray[i][1],"text": myArray[i][1],},
                  "insertText": {"objectId": myArray[i][2],"text": myArray[i][2],},
                  "insertText": {"objectId": myArray[i][3],"text": myArray[i][3],},
                  "insertText": {"objectId": myArray[i+1][1],"text": myArray[i+1][1],},
                  "insertText": {"objectId": myArray[i+1][2],"text": myArray[i+1][2],},
                  "insertText": {"objectId": myArray[i+1][3],"text": myArray[i+1][3],},
                  "insertText": {"objectId": myArray[i+2][1],"text": myArray[i+2][1],},
                  "insertText": {"objectId": myArray[i+2][2],"text": myArray[i+2][2],},
                  "insertText": {"objectId": myArray[i+2][3],"text": myArray[i+2][3],},
                  "insertText": {"objectId": myArray[i+3][1],"text": myArray[i+3][1],},
                  "insertText": {"objectId": myArray[i+3][2],"text": myArray[i+3][2],},
                  "insertText": {"objectId": myArray[i+3][3],"text": myArray[i+3][3],}},
                               ]};

Slides.Presentations.batchUpdate(resource, presentationId);   

}

}

数组中的每个元素都引用不同的项目，并包含：

• 项目名称
• 项目的状态
• 关于这个项目的一些随机信息

它们都是字符串。数组中的元素数量可能会有所不同，但它们始终遵循此结构

在演示中，我在主布局中创建了一个新布局，我将其命名为“new layout”。该布局有4个组，每个组中有3个占位符。每组占位符都应该填充不同项目的信息，这意味着一组占位符将填充

myArray[i][1]

、

myArray[i][2]

和

myArray[i][3]

到目前为止，我的代码如下：

var myArray = [[Project1,Status1,Info1],[Project2,Status2,Info2],...,[ProjectN,StatusN,InfoN]]

function CreatingSlides() {

var displayName = "NEW LAYOUT"; // Name of the layout that I created
var presentationId = SlidesApp.openById(PageId).getId(); //It is an existing presentation, so I just get its ID
var layouts = Slides.Presentations.get(presentationId).layouts;
var layout = {};

//The following is the array of elements. In this example,
//I only used 4 projects, but it may vary and may not be
//a multiple of 4.
var myArray = [["Project1","Status1","Info1"],["Project2","Status2","Info2"],["Project3","Status3","Info3"],["Project4","Status4","Info4"]];


//This loop searches for the layout that I created
for (i in layouts) {
  layout[layouts[i].layoutProperties.displayName] = layouts[i].objectId;
  }

//In the slide created, this loop will fill the information in it using the myArray
for (i in myArray) {
  var resource = {"requests": [{"createSlide": {"slideLayoutReference": {"layoutId": layout[displayName]},
                                                "placeholderIdMappings": [{"layoutPlaceholder": {"type": "SUBTITLE","index": 0},"objectId":myArray[i][1],},],
                                                "placeholderIdMappings": [{"layoutPlaceholder": {"type": "BODY","index": 0},"objectId":myArray[i][2],},],
                                                "placeholderIdMappings": [{"layoutPlaceholder": {"type": "BODY","index": 1},"objectId":myArray[i][3],},],
                                                "placeholderIdMappings": [{"layoutPlaceholder": {"type": "SUBTITLE","index": 1},"objectId":myArray[i+1][1],},],
                                                "placeholderIdMappings": [{"layoutPlaceholder": {"type": "BODY","index": 2},"objectId":myArray[i+1][2],},],
                                                "placeholderIdMappings": [{"layoutPlaceholder": {"type": "BODY","index": 3},"objectId":myArray[i+1][3],},],
                                                "placeholderIdMappings": [{"layoutPlaceholder": {"type": "SUBTITLE","index": 2},"objectId":myArray[i+2][1],},],
                                                "placeholderIdMappings": [{"layoutPlaceholder": {"type": "BODY","index": 4},"objectId":myArray[i+2][2],},],
                                                "placeholderIdMappings": [{"layoutPlaceholder": {"type": "BODY","index": 5},"objectId":myArray[i+2][3],},],
                                                "placeholderIdMappings": [{"layoutPlaceholder": {"type": "SUBTITLE","index": 3},"objectId":myArray[i+3][1],},],
                                                "placeholderIdMappings": [{"layoutPlaceholder": {"type": "BODY","index": 6},"objectId":myArray[i+3][2],},],
                                                "placeholderIdMappings": [{"layoutPlaceholder": {"type": "BODY","index": 7},"objectId":myArray[i+3][3],},],
                                                }
                                },
                 {"insertText": {"objectId": myArray[i][1],"text": myArray[i][1],},
                  "insertText": {"objectId": myArray[i][2],"text": myArray[i][2],},
                  "insertText": {"objectId": myArray[i][3],"text": myArray[i][3],},
                  "insertText": {"objectId": myArray[i+1][1],"text": myArray[i+1][1],},
                  "insertText": {"objectId": myArray[i+1][2],"text": myArray[i+1][2],},
                  "insertText": {"objectId": myArray[i+1][3],"text": myArray[i+1][3],},
                  "insertText": {"objectId": myArray[i+2][1],"text": myArray[i+2][1],},
                  "insertText": {"objectId": myArray[i+2][2],"text": myArray[i+2][2],},
                  "insertText": {"objectId": myArray[i+2][3],"text": myArray[i+2][3],},
                  "insertText": {"objectId": myArray[i+3][1],"text": myArray[i+3][1],},
                  "insertText": {"objectId": myArray[i+3][2],"text": myArray[i+3][2],},
                  "insertText": {"objectId": myArray[i+3][3],"text": myArray[i+3][3],}},
                               ]};

Slides.Presentations.batchUpdate(resource, presentationId);   

}

}

问题1：当数组中的元素数量可能不同时，如何执行此操作？

在这段代码中，我只使用myArray中的4个元素，因此创建的幻灯片中的所有占位符都将被填充。但是，如果元素数大于4，我不明白如何告诉它创建新幻灯片。此外，元素的数量不能是4的倍数（可以是5，可以是60，可以是72…）

问题2：我不知道如何正确使用请求中的objectID

我从谷歌应用程序脚本参考中看到的另一段代码中得到了这一部分。在其中，我了解到，在请求内部，if首先为objectId设置一个名称，然后使用该名称在占位符中写入内容。但是，这会产生一些问题：objectId有时不接受我试图给它的名称，或者objectId说它不能使用我建议的名称，因为它应该是唯一的。有更好的方法吗

问题3：是否可以不用写12行来填充占位符？

---

我认为这只是因为我不知道如何正确使用ObjectID（问题2）。因此，我必须分别命名幻灯片中的每个objectId。我相信有一些方法可以使用循环来实现这一点，但到目前为止，我还无法找到解决方案或理解它。

首先有一个建议：您使用的是和内置的混合。如果只使用SlidesApp，会简单得多，因为它可以满足您的需要，而且您不必担心对象是否正确

回答您的问题：

问题1：当数组中的元素数量可能不同时，如何执行此操作？ 这里的问题是布局中只有12个占位符。尝试填充超过该数量的内容是行不通的，因为您将用完要填充的占位符。这里的选项是：不要使用占位符，而是创建和定位文本框，或者以不同的方式显示数据。例如，每个项目使用一张幻灯片，其中包含3个占位符，一个用于项目名称、状态和信息

我建议您手工创建一个示例幻灯片，以设计您希望最终幻灯片的外观，并反向编写生成该幻灯片的代码。经常在幻灯片上用变量字符串替换所有文本，如

{{project_1}}:{{{status_1}}}

将非常有效

问题2：我不知道如何在请求中正确使用objectid 您可以尝试为占位符提供一个对象ID，然后使用InsertText设置内容。我认为您的问题在于占位符IDMappings不正确，您需要一个映射对象列表，而不是多次指定占位符IDMappings键（请参见此）

问题3：是否可以不用写12行来填充占位符？ 我认为这主要是由于您如何构建项目数据、幻灯片的布局以及占位符映射问题。解决这些问题应该会让这件事更容易处理

还应该更容易处理SlideApp（使用）
