Google Apps Script (Javascript) - findText返回相对于内联图像的位置，而不是段落

Question

我试图从findText的结果插入一个段落中间的图像，但是当在段落之前有其他图像时，它不会按计划工作。

目前，我的代码(部分基于对这个问题的回答)通过查找需要插入的位置，然后获取findText()返回的段落的子索引来工作。但是，如果有内联图像，则返回子索引作为段落的开始，但是findText的偏移量是图像末尾的字符，而不是段落的开始。

下面是脚本的相关部分:

function placeImage(start, end) {
  var d = DocumentApp.getActiveDocument()
  var s = d.getBody();
  var logoResult = s.findText(start);
  var placeHolderStart = logoResult.getStartOffset(); //position of image insertion
  var logoResult2 = s.findText(end, logoResult);
  var placeHolderEnd = logoResult2.getStartOffset(); //text between placeHolderStart and placeHolderEnd will be permanently deleted
  var textElement = logoResult.getElement();
  var paragraph= textElement.getParent();
  var childIndex = paragraph.getParent().getChildIndex(paragraph);  //gets paragraph number
  var par = s.getChild(childIndex).asParagraph(); //entire paragraph containing point of insertion
  var parcopy = par.copy();
  var totalLen = par.editAsText().getText().length-1;
  par.editAsText().deleteText(placeHolderStart, totalLen); //delete all text after insertion point; some will be added back later from parcopy
  parcopy.editAsText().deleteText(0, placeHolderEnd + 1); //this would be the remaining text that gets pasted at the end
  var resp = UrlFetchApp.fetch("https://www.google.com/images/srpr/logo11w.png");
  var logoBlob = resp.getBlob();
  var img = s.getChild(childIndex).appendInlineImage(logoBlob);
  var toMerge = s.insertParagraph(childIndex+1, parcopy);
  toMerge.merge();
  return 1;
}

一个段落包含几个子元素，例如文本字符串或图像。您需要获得段落内文本元素的索引，而不是文档内段落的索引。试试这个

function placeImage(start, end) {
  var d = DocumentApp.getActiveDocument()
  var s = d.getBody();
  var logoResult = s.findText(start);
  var placeHolderStart = logoResult.getStartOffset(); //position of image insertion
  var logoResult2 = s.findText(end, logoResult);
  var placeHolderEnd = logoResult2.getEndOffsetInclusive(); //text between placeHolderStart and placeHolderEnd will be permanently deleted
  var textElement = logoResult.getElement(); 
  var text = textElement.getText();
  var paragraph = textElement.getParent();
  var childIndex = paragraph.getChildIndex(textElement);  //gets index of text element in paragaph
  var textSecondHalf = text.substring(placeHolderEnd + 1);
  textElement.deleteText(placeHolderStart, text.length-1);
  paragraph.insertText(childIndex+1, textSecondHalf);
  var resp = UrlFetchApp.fetch("https://www.google.com/images/srpr/logo11w.png");
  var logoBlob = resp.getBlob();
  paragraph.insertInlineImage(childIndex+1, logoBlob);
}
