Question

谷歌应用程序脚本仍然相当新，并且看到了一个很糟糕的文档课程。

https://developers.google.com/apps-script/class_docslistdialog。我希望用它来允许我的用户从他们的Google集合中选择一个文档。

以下是我的开始：

var app = UiApp.createApplication().setHeight(400).setWidth(600);
var ss = SpreadsheetApp.getActiveSpreadsheet();
var doclisthandler = app.createServerHandler('selectionhandler');
var doclist = app.createDocsListDialog().showDocsPicker().addSelectionHandler(doclisthandler); 
ss.show(app);}

function selectionhandler(e)
{    var app = UiApp.getActiveApplication();
var selname = e.parameter.doclist;           
toastDoc.toast(selname,'here in selectionhandler',4);
return app;
}

我的toastDoc.toast只是为了验证我的selectionhandler函数是否有效并查看返回的内容。 selname返回'undefined'。

除了上面的网址之外，我在这个课上寻找了一些例子，但我什么也没得到:(

理想情况下，我想返回选中的文档ID，以便我的脚本可以进行进一步处理......

任何帮助将不胜感激

Answer 1

要查看它返回的内容，您可以使用以下功能。一切都将在Logger中返回

function selectionhandler(e){
  var app = UiApp.getActiveApplication();
  Logger.log(e.parameter.items[0].id);
  Logger.log(e.parameter.items[0].name);
  Logger.log(e.parameter.items[0].url);
//Or to check everything which is returned in e.parameter
  Logger.log(e.parameter);
  return app;
}

希望有所帮助

您似乎忘了向处理程序添加回调元素...

addCallbackElement(name);

的问候，哔叽

编辑：嗨乔，我也在做类似这样的事情......我认为到目前为止展示我所拥有的东西可能很有趣......还没有完成;-) 我粘贴整个东西，所以你可以仔细测试它：

function onOpen() {
  var ss = SpreadsheetApp.getActiveSpreadsheet();
  var menuEntries = [ {name: "Doclist UI", functionName: "doclistUI"},

                    ];
  ss.addMenu("Utilities", menuEntries);//
}
//
function doclistUI(){
  var folderlist = new Array();
  var folders=DocsList.getFolders()
  for(ff=0;ff<folders.length;++ff){
    folderlist.push(folders[ff].getName());
    }
  var app = UiApp.createApplication().setHeight(260).setWidth(700).setStyleAttribute('background', 'beige')
      .setStyleAttribute("position", "relative").setStyleAttribute("left", "10").setStyleAttribute("top", "12px");
  app.setTitle("Doclist UI");
  var panel = app.createVerticalPanel()
  var hpanel = app.createHorizontalPanel();

  var Flab=app.createLabel('Folder List').setWidth("80");
  var Dlab=app.createLabel('Document List').setWidth("100");
  var spacer=app.createLabel(' ').setWidth("30");
  var spacer2=app.createLabel(' ').setWidth("15");
//  
  Flist.addItem('Choose a folder');
  for(ff=0;ff<folderlist.length;++ff){
    Flist.addItem(folderlist[ff]);
  }
  var anchor = app.createAnchor('open ', "www.google.com").setId('anchor').setVisible(false);
  hpanel.add(Flab).add(Flist).add(spacer).add(Dlab).add(Dlist)
