Google Apps脚本:如何在Google文档中查找listItem对象并向其中插入项目? [英] Google Apps Script: How to find a listItem object in a google document and insert a item to it?

问题描述

在文档示例之后，我正在尝试创建一个函数来搜索google文档中的数字列表，如果找到了该函数，则向该列表添加一个新项目.但是我收到以下错误消息:Cannot find method setListId(string). (line 21, file "test")，或者，如果我更改第21行的内容(将elementContent替换为newElement)，则会收到消息:Preparing for execution...，并且什么也没有发生.如何解决?

Following the documentation sample, I'm trying to create a function that searchs for a numerated list in a google document and, if finds it, adds a new item to that list. But I get this error: Cannot find method setListId(string). (line 21, file "test") or, if I change line 21 content (replacing elementContentfor newElement), I get the message: Preparing for execution... and nothing happens. How to fix it?

这是我的代码:

function test() {
  var elementContent = "New item testing"; // a paragraph with its formating
  var targetDocId = "1R2c3vo9oOOjjlDR_n5L6Tf9yb-luzt4IxpHwwZoTeLE";  
  var targetDoc = DocumentApp.openById(targetDocId);
  var body = targetDoc.getBody();
  for (var i = 0; i < targetDoc.getNumChildren(); i++) {
    var child = targetDoc.getChild(i);
    if (child.getType() == DocumentApp.ElementType.LIST_ITEM){
        var listId = child.getListId();
        var newElement = body.appendListItem(elementContent);
        newElement.setListId(newElement);
        Logger.log("child = " + child);

    }
  }
}

推荐答案

在我发表评论之后，我尝试使用您的脚本来查看发生了什么，然后在下面提出了该代码...

Following my comment, I tried to play with your script to see what happened and I came up with that code below...

我并不是说它可以解决您的问题和/或是实现所需目标的最佳方法，但至少可以使结果达到预期效果.

I'm not saying it solves your issue and/or is the best way to achieve what you want but at least it gives a result that works as expected.

请考虑将其视为新游乐场"，并继续对其进行试验以使其变得更好；-)

Please consider it as a "new playground" and keep experimenting on it to make it better ;-)

function test() {
  var elementContent = "New item testing"; // a paragraph with its formating
  var targetDocId = DocumentApp.getActiveDocument().getId();  
  var targetDoc = DocumentApp.openById(targetDocId);
  var body = targetDoc.getBody();
  var childIndex = 0;
  for (var i = 0; i < targetDoc.getNumChildren(); i++) {
    var child = targetDoc.getChild(i);
    if (child.getType() == DocumentApp.ElementType.LIST_ITEM){
      while(child.getType() == DocumentApp.ElementType.LIST_ITEM){
        child = targetDoc.getChild(i)
        childIndex = body.getChildIndex(child);
        Logger.log(childIndex)
        i++
      }
      child = targetDoc.getChild(i-2)
      var listId = child.getListId();
      Logger.log(childIndex)
      var newElement = child.getParent().insertListItem(childIndex, elementContent);
      newElement.setListId(child);
      break;
    }
  }
}
