在HTMLService / Google Apps脚本中使用日期选择器返回值 [英] Returning a value using Date picker in HTMLService / Google Apps Script

问题描述

我试图捕获将在基于文档容器的GAS中使用的日期范围。我已经成功地显示了一个对话框，其中显示了两个jquery datepicker对象，在这篇文章中使用了Serge伟大的例子：

。
。
...但是，如何将这两个日期值从html逻辑返回给我的GAS代码？

I'm trying to capture a date range that will be used inside a Document container-based GAS. I've been successful displaying a dialog box that shows two jquery datepicker objects using Serge's great example in this post: Date picker in HTMLService / Google Apps Script . . ...but, how can I return the two date values back to my GAS code from the html logic?

预先感谢！

function onOpen() {
  var ui = DocumentApp.getUi();
  ui.createMenu('Create Calendar')
      .addItem('Provide Date Range', 'showDialog')
      .addToUi();
}

function showDialog() {
  var html = HtmlService.createHtmlOutputFromFile('dateDialog')
      .setWidth(500)
      .setHeight(400);
  DocumentApp.getUi() 
      .showModalDialog(html, 'Please provide a Date Range');
  Logger.log("HTML return = %s", html.getContent());     // What does html contain?
}

推荐答案

准备一个服务器端函数来接收您的输入。这只记录它：

Prepare a server-side function to receive your input. This one only logs it:

function submitDates(startDate,endDate) {
  Logger.log(JSON.stringify(arguments));
  // To send error messages, throw an exception.
  // e.g. if (invalid) throw new error("Invalid date")
}

更改按钮处理程序在您的HTML。收集输入数据并使用 google.script.run 传递给服务器函数，而不是关闭对话框。将处理程序附加到跑步者;例如，成功处理程序将关闭窗口。失败处理程序将显示服务器端错误。

Change the button handler in your html. Instead of closing the dialog, collect the input data and pass it to the server function using google.script.run. Attach handler to the runner; a success handler will close the window, for example. A failure handler will display server-side errors.

<input type="button" value="Create" onclick="submitDates()" />

将此脚本添加到您的html底部：

Add this script to the bottom of your html:

<script>
// Pass input dates to server-side submitDates()
function submitDates() {
  var startDate = $("#startdatepicker").val();
  var endDate = $("#enddatepicker").val();

  google.script.run
        .withSuccessHandler(
           // Dates delivered, close dialog
           function() {
             google.script.host.close();
           })
           // Display failure messages
         .withFailureHandler(
           function() {
             var div = $('<div id="error" class="error">' + msg + '</div>');
             $(element).after($("#demo"));
           })
         .submitDates(startDate,endDate);
}

</script>
