“e”未定义Google Script错误

Question

我最近问了这个问题： Have a listbox populate with every folder in myDrive

我得到了一个答案（感谢Serge insas的帮助！）但我正在尝试将他所做的内容纳入我当前的用户界面。我创建了列表框，除了他所调用的函数之外的所有内容，“function folderSelect”，当我尝试将其移动到我的UI时，在运行脚本时出现“e undefined”错误。我还需要确保当我在下拉菜单中选择该文件夹时，生成文档时，它会将该文档保存在该文件夹中。 （对不起，我已经问了很多关于这一切的问题。在我来到这里之前，我试着尝试自己做我需要做的事情，但是当我不知道自己在做什么时很难。）

当前项目的PasteBin：http://pastebin.com/GVSvfcqG

这是我到目前为止所做的：

 function getTemplates() {
      var doc = SpreadsheetApp.getActiveSpreadsheet();
      var app = UiApp.createApplication().setTitle('Generate from template');
      // Create a grid with 3 text boxes and corresponding labels
      var grid = app.createGrid(5, 2);
      grid.setWidget(0, 0, app.createLabel('Template name:'));
      var list = app.createListBox();
      list.setName('Templates');
      grid.setWidget(0, 1, list);
      var docs = DocsList.getFolder("Templates").getFilesByType("document");
      for (var i = 0; i < docs.length; i++) {
        list.addItem(docs[i].getName(),docs[i].getId());
      }
      grid.setWidget(1, 0, app.createLabel('Row:'));
      var row = app.createTextBox().setName('row');
      row.setValue(SpreadsheetApp.getActiveSpreadsheet().getActiveRange().getRow());
      grid.setWidget(1, 1, row);

    ///////////////////////////////This is what i am trying to implement into my UI//////////////////////////////////////////////
       var curFN = app.createTextBox().setText('MyDrive/').setName('curFN').setId('curFN').setWidth('400');

感谢Serge insas的所有帮助，他修复了一切，并且它完美无缺，如果您需要的话，我想与大家分享：将一行电子表格文档导出到工作文档中，将其放入特定文件夹并创建该工作文档的PDF。使模板使用{A} {B}等等，以便放置信息。

Template Generator By: Andre Fecteau - klutch2013@gmail.com
Original Code From: kiszal@gmail.com (Found in the template gallery by searching "Templates" It is the first One.
Major Help from: Serge Insas On Stack Overflow (He did most of the work.)
Link 1: https://stackoverflow.com/questions/18147798/e-undefined-google-script-error
Link 2: https://stackoverflow.com/questions/18132837/have-a-listbox-populate-with-every-folder-in-mydrive

How To Use: 
First: each column is designated in your Template by {Column Letter} for example for column A it would be {A}
Second: You can change this, but your Template must be in a folder called "Templates." This folder can be anywhere in your drive.
Third: Click "Generate Documents Here!" Then click "Export Row to Document"
Fourth: Type in the row you want to export. Chose your Folder Path. Click Submit. 
NOTE ON FOURTH STEP: If you want your number to skip the header row add a +1 to line 28. 
This would mean if you typed "2" in the row box it actually exports row 3. I took this out because it can get confusing at times.

NOTE: Line 67 you can edit the word "Templates" to whatever folder you saved your Template into.

Feel free to edit this code as you wish and for your needs. That is what I did with the original code.
So there is no reason I should restrict what others do with this code.

Answer 1

您无法按照您的方式集成此代码... handler函数是在用户完成某个操作并且callBackElement为该函数带来值时执行的函数使用e对象（e代表事件信息）。

如果您尝试在主代码中获取e.parameter，它将尝试获取尚未定义的值并生成您获得的错误。

以下是我的代码的正确实现，请仔细检查以了解它是如何工作的。

function getTemplates() {
  var doc = SpreadsheetApp.getActiveSpreadsheet();
  var app = UiApp.createApplication().setTitle('Generate from template');
  // Create a grid with 3 text boxes and corresponding labels
  var grid = app.createGrid(5, 2);
  grid.setWidget(0, 0, app.createLabel('Template name:'));
  var list = app.createListBox();
  list.setName('Templates');
  grid.setWidget(0, 1, list);
  var docs = DocsList.getFolder("Templates").getFilesByType("document");
  for (var i = 0; i < docs.length; i++) {
    list.addItem(docs[i].getName(),docs[i].getId());
  }
  grid.setWidget(1, 0, app.createLabel('Row:'));
  var row = app.createTextBox().setName('row');
  row.setValue(SpreadsheetApp.getActiveSpreadsheet().getActiveRange().getRow());
  grid.setWidget(1, 1, row);
  var curFN = app.createTextBox().setText('MyDrive/').setName('curFN').setId('curFN').setWidth('400');
  var curFID = app.createTextBox().setText('x').setName('curFID').setId('curFID').setVisible(false);
  var listF = app.createListBox().setName('listF').setId('listF').addItem('please select a folder','x');
  grid.setText(2,0,'Choose a folder in your drive').setWidget(2,1,curFN).setWidget(3,1,curFID).setWidget(4,1,listF);
  var folders = DocsList.getRootFolder().getFolders();
  for (var i = 0; i < folders.length; i++) {
    listF.addItem(folders[i].getName(),folders[i].getId())
  } 
  var handlerF = app.createServerHandler('folderSelect').addCallbackElement(grid);
  listF.addChangeHandler(handlerF);
  var panel = app.createVerticalPanel();
  panel.add(grid);
  var button = app.createButton('Submit');
  var handler = app.createServerClickHandler('generateDocument');
  handler.addCallbackElement(grid);
  button.addClickHandler(handler);
  // Add the button to the panel and the panel to the application, then display the application app in the Spreadsheet doc
  panel.add(button);
  app.add(panel);
  doc.show(app);
}

function folderSelect(e){
  var app = UiApp.getActiveApplication();
  var currentFN = e.parameter.curFN;
  var currentFID = e.parameter.listF;
  Logger.log(currentFID);
  var listF = app.getElementById('listF');
  var curFN = app.getElementById('curFN');
  var curFID = app.getElementById('curFID');
  if(currentFID=='x'){currentFID=DocsList.getRootFolder().getId() ; curFN.setText('MyDrive/')};
  var startFolder = DocsList.getFolderById(currentFID);
  var folders = startFolder.getFolders();
  listF.clear().addItem('no other subFolder','x').addItem('Go back to Root','x');
  if(folders.length>0){listF.clear(); listF.addItem('please select a subFolder','x')};
  for (var i = 0; i < folders.length; i++) {
    listF.addItem(folders[i].getName(),folders[i].getId())
  } 
  curFN.setText(currentFN+DocsList.getFolderById(currentFID).getName()+'/');
  if(currentFID==DocsList.getRootFolder().getId()){curFN.setText('MyDrive/')};
  curFID.setText(currentFID);
  return app;

根据您的评论，以下是将文档移动到所选文件夹并在同一文件夹中创建pdf文件的修改：

function generateDocument(e) {
  var template = DocsList.getFileById(e.parameter.Templates);
  var Sheet = SpreadsheetApp.getActiveSpreadsheet();
  var row = e.parameter.row
  var currentFID = e.parameter.listF;
  var myDocID = template.makeCopy(Sheet.getRange('B'+row).getValue()+' - '+Sheet.getRange('E'+row).getValue()+' - '+Sheet.getRange('D'+row).getValue()+' - '+Sheet.getRange('X'+row).getValue()).getId();
  var myDoc = DocumentApp.openById(myDocID);
  var copyBody = myDoc.getActiveSection();
  var Sheet = SpreadsheetApp.getActiveSpreadsheet();
  var myRow = SpreadsheetApp.getActiveSpreadsheet().getRange(row+":"+row);
  for (var i=1;i<Sheet.getLastColumn()+1;i++){
    var myCell = myRow.getCell(1, i);
    copyBody.replaceText("{"+myCell.getA1Notation().replace(row,"")+"}", myCell.getValue());
  }
  myDoc.saveAndClose();
  var destFolder = DocsList.getFolderById(currentFID);
  var doc = DocsList.getFileById(myDocID);// get the document again but using docsList this time...
  doc.addToFolder(destFolder);// add it to the desired folder
  doc.removeFromFolder(DocsList.getRootFolder());// I did it step by step to be more easy to follow
  var pdf = DocsList.getFileById(myDocID).getAs("application/pdf");
  destFolder.createFile(pdf);// this will create the pdf file in your folder
  var app = UiApp.getActiveApplication();
  app.close();
  return app;
}
