Question

我已经设置了一个可安装的触发器，该触发器在我的Google工作表打开时会启动Google选择器功能[showPicker（）]。任何人都可以通过网址访问Google工作表。

当我打开Google工作表时，脚本运行良好，并且文件选择器显示在屏幕上。但是，当我登录与Google工作表共享的其他帐户时，脚本似乎无法运行，并且在打开电子表格时文件选择器也不会显示。

.GS文件

function showPicker() {
  var html = HtmlService.createHtmlOutputFromFile('Picker.html')
      .setWidth(600)
      .setHeight(425)
      .setSandboxMode(HtmlService.SandboxMode.IFRAME);
 SpreadsheetApp.getUi().showModalDialog(html, 'Select CSV File');
}

function getOAuthToken() {
  DriveApp.getRootFolder();
  return ScriptApp.getOAuthToken();
}

Picker.html文件

我尝试浏览有关共享用户授权的文档，但是我有点迷茫，不知道为什么脚本无法启动？任何帮助将不胜感激：）

Answer 1

只有电子表格的所有者才能触发html对话框。当其他用户打开您的电子表格时，将创建一个错误报告，指出他们无权调用无模式对话框。我猜这是一项安全功能。

其他用户可以通过从菜单下拉菜单中进行选择来手动打开选择器。

但是，您可以为打开电子表格的每个人触发Browser.msgBox（）。
