替换多个 Google 文档中的超链接

Question

我输入了 ziganotschka 在上发布的以下代码：

function myFunction() {
  var oldLink="http://www.googledoclink1.com";
  var newLink="http://www.googledoclinkA.com";
  var oldLink2="http://www.googledoclink2.com";
  var newLink2="http://www.googledoclinkB.com";
  var files = DriveApp.getFiles();   // Note: this gets *every* file in your Google Drive
  while (files.hasNext()) {
    var file = files.next();
    Logger.log(file.getName());
    var doc = DocumentApp.openById(file.getId());
    var link=doc.getBody().findText(oldLink).getElement().asText(); 
    var link2=doc.getBody().findText(oldLink2).getElement().asText(); 
    link.setLinkUrl(newLink);   
    doc.replaceText(oldLink, newLink);
    link2.setLinkUrl(newLink2);   
    doc.replaceText(oldLink2, newLink2);
  }
  Logger.log("Done")
}

...但我收到此错误消息：

TypeError: Cannot call method "getElement" of null. (line 11, file "Replace Hyperlinks")

我该如何解决这个问题？我必须做什么？

我也只是想从文件夹中提取文件，而不是 Google 驱动器中的所有文件，所以我替换了

var files = DriveApp.getFiles();

和

var files = DriveApp.getFolderById("insert folder ID").getFiles();

那行得通，对吗？

谢谢，劳伦

Answer 1

第一个问题：

您正在遍历驱动器上/文件夹中的所有文件
其中一些文件可能不包含旧的 link“http://www.googledoclink1.com”
这会引发错误
您需要执行一个语句来检查是否包含 link，如果不包含 - 跳转到下一个文件

关于你的第二个问题：

是的，您可以使用 var files = DriveApp.getFolderById("insert folder ID").getFiles();
您也可以使用 var files = DriveApp.getFolderById("insert folder ID").getFilesByType(MimeType.GOOGLE_DOCS); 仅检索 Google 个文档文件

样本：

function myFunction() {
  var oldLink="http://www.googledoclink1.com";
  var newLink="http://www.googledoclinkA.com";
  var oldLink2="http://www.googledoclink2.com";
  var newLink2="http://www.googledoclinkB.com";
  var files = DriveApp.getFolderById("insert folder ID").getFilesByType(MimeType.GOOGLE_DOCS);
  while (files.hasNext()) {
    var file = files.next();
    if(file){
      var doc = DocumentApp.openById(file.getId());
      var link=doc.getBody().findText(oldLink);
      var link2=doc.getBody().findText(oldLink2);
      if(link){
        link=link.getElement().asText(); 
        link.setLinkUrl(newLink);   
        doc.replaceText(oldLink, newLink);
      }
      if(link2){
        link2=link2.getElement().asText(); 
        link2.setLinkUrl(newLink2);   
        doc.replaceText(oldLink2, newLink2);
      }
    }
  }
  Logger.log("Done")
}

Example: Suppose I had the hyperlink text: "Symptom to Diagnosis: An Evidence-Based Guide, 3e" with the URL accessmedicine.mhmedical.com/book.aspx?bookid=1088. I want to replace that hyperlink text with "Symptom to Diagnosis: An Evidence-Based Guide, 4e" with the URL accessmedicine.mhmedical.com/book.aspx?bookid=2715. So, I want to find every instance of the old hyperlink and replace it with the new hyperlink. I'm wondering where all that belongs in the code...does it need quotation marks?

示例解决方案：

function myFunction() {
  var oldLinkText="Symptom to Diagnosis: An Evidence-Based Guide, 3e";
  var newLinkText="Symptom to Diagnosis: An Evidence-Based Guide, 4e";
  var oldLinkURL="accessmedicine.mhmedical.com/book.aspx?bookid=1088";
  var newLinkURL="accessmedicine.mhmedical.com/book.aspx?bookid=2715";
  var oldLinkText2="XXX";
  var newLinkText2="XXY";
  var oldLinkURL2="accessmedicine.XXX";
  var newLinkURL2="accessmedicine.XXY";
  var files = DriveApp.getFolderById("insert folder ID").getFilesByType(MimeType.GOOGLE_DOCS);  
  while (files.hasNext()) {
    var file = files.next();
    if(file){
      var doc = DocumentApp.openById(file.getId());
      var link=doc.getBody().findText(oldLinkText);
      var link2=doc.getBody().findText(oldLinkText2);
      if(link){
        link=link.getElement().asText(); 
        link.setLinkUrl(newLinkURL);   
        doc.replaceText(oldLinkText, newLinkText);
      }
      if(link2){
        link2=link2.getElement().asText(); 
        link2.setLinkUrl(newLinkURL2);   
        doc.replaceText(oldLinkText2, newLinkText2);
      }
    }
  }
  Logger.log("Done")
}
