使用getLinkUrl（偏移量）的Google Apps脚本问题

Question

我正试图弄清楚如何在Google Apps脚本中使用getLinkUrl(offset)。

我在这里找到了参考资料 - http://googlescriptreference.com/Document/Text/getlinkurloffset/，但我在网上找不到任何例子。

此GAS返回日志中的Paragraphin

var paragraph = tableCell.getChild(0);

此GAS在日志中返回the text string in the paragraph

var paragraphText = paragraph.getText();

此GAS在日志中返回NULL

var paragraphText = paragraph.getLinkUrl();

此GAS返回错误（无法找到方法getLinkUrl（数字）。）并且日志中没有任何内容

var paragraphText = paragraph.getLinkUrl(2);

有人可以帮我理解如何使用getLinkUrl(offset)？

谢谢你的帮助！

Answer 1

我试图直接在段落元素上使用getLinkUrl(offset)（不是工作示例），但我需要在asText()之前使用getLinkUrl(offset)方法。

不工作

var paragraphText = paragraph.getLinkUrl(2);

工作

var paragraphText = paragraph.asText().getLinkUrl(2);

Google Document https://docs.google.com/document/d/136G549zIYPYBndXs70ZnR_wEFg5fPST9ZGsOlTgmDyM/edit

//Works if link is on a word or words instead of entire paragraph

function myFunctionP1() {
  //Find out how many Children there are
  var body = DocumentApp.getActiveDocument().getBody();
  Logger.log(body.getNumChildren());

  //Find out which child is table
  var table = body.getChild(2); //table is child#2
  Logger.log(table);

  //Find tableCell inside of table
  var tableCell = table.getChild(0).getChild(0); //tableCell
  Logger.log(tableCell)

  //Find paragraph inside of tableCell 
  //I think, but I'm not sure, the HYPERLINK will be found somewhere within the PARAGRAPH element. But I can't figure out how to get to it.
  var paragraph = tableCell.getChild(0); //paragraph element
  Logger.log(paragraph)

  //Get paragraph text 
  var paragraphText = paragraph.asText().getLinkUrl(2); //paragraph text
  Logger.log(paragraphText)


}

  var paragraph = tableCell.getChild(0); //paragraph element
  Logger.log(paragraph)

  //Get paragraph text 
  var paragraphText = paragraph.getText(); //paragraph text
  Logger.log(paragraphText)

  //Get HYPERLIINK from paragraph text 
  var paragraphHYPERLINK = paragraph.getLinkUrl(); //paragraph text
  Logger.log(paragraphHYPERLINK)  

}
