防止双击谷歌应用脚​​本

Question

当我双击表单提交两次。它创建重复的行。如何防止双击？

谢谢！

function doGet(e) {
  //Logger.log( Utilities.jsonStringify(e) );
  if (!e.parameter.page) {
    // When no specific page requested, return "home page"
    return HtmlService.createTemplateFromFile('employee').evaluate()
    .setTitle('care backup').setSandboxMode(HtmlService.SandboxMode.NATIVE);
  }
  // else, use page parameter to pick an html file from the script
  return HtmlService.createTemplateFromFile(e.parameter['page']).evaluate()
  .setTitle('care').setSandboxMode(HtmlService.SandboxMode.NATIVE);
}

我没有对此进行测试，但只是一个选项 - 还设置一个基于时间的触发器以每隔一段时间运行一次功能重置？

var recentSubmit = 0;

function doGet(e) {
  //Logger.log( Utilities.jsonStringify(e) );
if (recentSubmit = 0){  
  if (!e.parameter.page) {
    var recentSubmit = 1;
    // When no specific page requested, return "home page"
    return HtmlService.createTemplateFromFile('employee').evaluate()
    .setTitle('care backup').setSandboxMode(HtmlService.SandboxMode.NATIVE);
  }
  // else, use page parameter to pick an html file from the script
  return HtmlService.createTemplateFromFile(e.parameter['page']).evaluate()
  .setTitle('care').setSandboxMode(HtmlService.SandboxMode.NATIVE);
  }
  Logger.log("Submitted a form to recently, try again later...");
}

function reset() {
var recentSubmit = 0;
 }

您可以尝试使用createClientHandler.forEventSource().setEnabled(false)。它可以禁用提交按钮。它已被弃用，但现在仍然有效。

完整的代码实现示例在这个SO post:

function onOpen() {

  var app = UiApp.createApplication();
  app.setTitle('My Title');
  app.setHeight(150);
  app.setWidth(300);

  var form = app.createFormPanel();
  var flow = app.createFlowPanel();

  flow.add(app.createHidden("action", 'action'));
  flow.add(app.createLabel('My Label'));

  //Submit
  var submit = app.createButton('Run', app.createServerHandler('notif').addCallbackElement(form)).setId('run');
  var cliHandler = app.createClientHandler().setEnabled().setEnabled(false);
  submit.addClickHandler(cliHandler);
  flow.add(submit);

  form.add(flow);
  app.add(form);
  var spreadsheet = SpreadsheetApp.getActiveSpreadsheet();
  spreadsheet.show(app);

};

function notif(){  
  //DO NOTHING. JUST SHOW THE button is DISABLED.
}

点击后按钮变灰..
