javascript - Google UiApp 中的 Google Apps 脚本验证问题

Question

我一直在尝试了解 Google 协作平台中的 Google Apps 脚本验证，但尚未使验证部分正常工作。

我需要验证两件事:

1. “位置”文本框中至少有 5 个字符(最多 100 个)
2. 已从下拉列表中选择了一个日期

如果两个条件都不满足，那么它应该使两件事可见:

1. 警告异常
2. 警告异常

就是这样。

我的其余逻辑运行良好。我才刚刚开始。

下面列出了完整的逻辑。我已将我们的域信息替换为 xxxxxxxxx。

到目前为止，它要么从不显示消息并且什么都不做，要么只是正确处理其中一项以允许它继续前进。它们都应满足要求，否则应抛出 warnExceptions。如果用户加载了页面但没有填写任何一个/或区域，只是按下了按钮，这也是一样的。

如何验证位置文本框和日期框？

Answer 1

像这样尝试(见下文)我更改了一些验证并在 2 个处理程序中分开 + 添加了一个“清除”处理程序以便能够单击以删除警告... test code here

您还必须添加一些东西来清除服务器处理程序中的警告，为什么不将图像和文本警告组合在一个小部件中？ (更容易清洁)

代码如下:

function doGet(e) {
  var text= new Array();
  var app = UiApp.createApplication();
  var hpanel = app.createGrid(4, 6).setId('pannel');
  var clearHandler = app.createClientHandler().forEventSource().setVisible(false)
  var hpanelException = app.createGrid(2,3).setId('hpanelException');
  var location = app.createTextBox().setName('location').setId("location").setWidth('200');
  var minuteTaker = app.createListBox().setName('minuteTaker').setId("minuteTaker").setWidth('200')
   for (var i = 0 ; i < councilMembers.length; i++) {
    minuteTaker.addItem(councilMembers.valueOf()[i]);
                    }

  var dateBox = app.createDateBox().setId('dateBox').setName('dateBox').setFireEventsForInvalid(false);
  var hour = app.createListBox(false).setId('hour').setName('hour')
//  var hour = app.createListBox(false).setId('hour').setName('hour')
  for(h=1;h<13;++h){hour.addItem(h)}
  var min = app.createListBox(false).setId('minute').setName('minute')
  .addItem('00').addItem('15').addItem('30').addItem('45'); 
  var amPm = app.createListBox(false).setId('am').setName('amPm')
  .addItem('AM').addItem('PM');  
  var dateTimeLabel = app.createLabel('',false).setId('dateTimeLabel');
  var submit = app.createButton('Create Minutes').setId('submit').setPixelSize(196, 25);
  var nextSteps = app.createAnchor('Please click here to see the minutes archive.', 'https://drive.google.com/xxxxxxxxxx/folderview?xxxxxxxxxx').setId('nextSteps').setVisible(false);

// Setup error message 
  var warnException =app.createImage('https://sites.google.com/xxxxxxxxxx/minutes/create-new-minutes/Opps.png').setId('warnException').setVisible(false).addClickHandler(clearHandler);
  var warnExceptionMes = app.createLabel('The date and Location are required. Please try again.').setStyleAttribute('font-weight', 'normal').setStyleAttribute('font-size','14px').setVisible(false).addClickHandler(clearHandler);

// handlers
  var handler0 = app.createClientHandler()
  .validateLength(location, 0, 5)
  .forTargets(warnException).setVisible(true)
  .forTargets(warnExceptionMes).setVisible(true);
  var handler1 = app.createClientHandler()
  .validateNotMatches(dateBox, '2', 'g')
  .forTargets(warnException).setVisible(true)
  .forTargets(warnExceptionMes).setVisible(true);

  var handler2 = app.createServerHandler('handlerFunction')
  .validateLength(location, 6, 100).validateMatches(dateBox, '2', 'g')
  .addCallbackElement(location).addCallbackElement(dateBox).addCallbackElement(hpanel);

  submit.addClickHandler(handler0).addClickHandler(handler1).addClickHandler(handler2);

  hpanel.setWidget(0,0,app.createLabel('Select Date'))
   .setWidget(0,1,app.createLabel('Hour'))
   .setWidget(0,2,app.createLabel('Minutes'))
   .setWidget(0,3,app.createLabel('AM/PM'))
   .setWidget(0,4,app.createLabel('Location'))
   .setWidget(0,5,app.createLabel('Minute Taker'))

  hpanel.setWidget(1,0,dateBox)
   .setWidget(1,1,hour)
   .setWidget(1,2,min)
   .setWidget(1,3,amPm)
   .setWidget(1,4,location)
   .setWidget(1,5,minuteTaker)

   hpanel.setWidget(2,5,submit)
   app.add(hpanel);//.add(warnException).add(warnExceptionMes);

  hpanelException.setWidget(1,1,warnException).setStyleAttribute("text-align", "right")
   .setWidget(1,2,warnExceptionMes)
  // .setWidget(1,2,nextSteps)
   app.add(hpanelException);
   return app;
     }

编辑您评论后的第二个版本。我模拟了一个需要一些时间的服务器功能，因此您可以看到所有步骤。 + 我按照建议合并了警告。 (演示代码更新版本 2)
