在项目中使用Google Apps脚本功能

Question

我是Google Apps脚本的新手，很好奇我如何使用自己项目中创建的功能。例如，我有一个脚本绑定到只有一个函数的电子表格：

function addOrder(title, content) {
  var sheet = SpreadsheetApp.getActiveSheet();
  sheet.appendRow([ Date(), title, content]);
}

它只需要2个参数，并使用该数据向电子表格添加一行。我已将其部署为Web应用程序，但我不确定如何在JSFiddle之类的环境中使用此功能。任何帮助表示赞赏。

电子表格绑定脚本运行服务器端，您使用的SpreadsheetApp.getActiveSheet()方法仅适用于电子表格绑定脚本的上下文，因为它是脚本实际“看到”活动电子表格的唯一情况。当您将其部署为webapp时，您必须告诉脚本它必须使用哪个电子表格，例如使用SpreadsheetApp.openById('spreadsheet ID')方法。

但即使这样做也不允许在Google环境之外使用此类代码（例如在JS小提琴中），因为SpreadsheetApp特定于Google Apps服务。

您必须记住Google Apps脚本基于基于在JavaScript上，但不是“普通”JavaScript，它使用了许多仅与Google Apps相关的特定服务。

修改以回复以下评论：

电子表格中用作数据服务器的代码如下所示:(这是作为没有用户界面的webapp部署的。它作为服务运行

function doGet(e) {
  if(e.parameter.mode==null){return ContentService.createTextOutput("error, wrong request").setMimeType(ContentService.MimeType.TEXT)};
  var mode = e.parameter.mode;
  var value = e.parameter.value;
  var ss = SpreadsheetApp.openById('1yad5sZZt-X6bIftpR--OSyf3VZWf3Jxx8UJBhh7Arwg');
  var sh = ss.getSheets()[0];
  if(mode=='read'){
    var sheetValues =  sh.getDataRange().getValues();// get data from sheet
    var valToReturn = ContentService.createTextOutput(JSON.stringify(sheetValues)).setMimeType(ContentService.MimeType.JSON);
    return valToReturn;// send it as JSon string
    }
  if(mode=='write'){
    var val = Utilities.base64Decode(value,Utilities.Charset.UTF_8);// decode base64 and get an array of numbers
    Logger.log(val);// see it !
    var stringVal = ''; // create an empty string
    for(var n in val){
      stringVal += String.fromCharCode(val[n]);// add each character in turn
    }
    var sheetValues =  JSON.parse(stringVal);// convert the string into an object (2D array)
    Logger.log(sheetValues);// check result
    sh.getRange(1,1,sheetValues.length,sheetValues[0].length).setValues(sheetValues);// update the sheet
    return ContentService.createTextOutput(JSON.stringify(sheetValues)).setMimeType(ContentService.MimeType.JSON);// send back the result as a string
    }
  return ContentService.createTextOutput('error').setMimeType(ContentService.MimeType.TEXT);// in case mode is not 'read' nor 'write'... should not happen ! 
}

您可以通过其网址+参数调用此服务，它将在电子表格中获取/设置值。这是一个基本的例子，但效果很好。

下面是webapp code

中使用此服务的Ui的this spreadsheet

var styleButton = {'padding':'5px', 'border-radius':'5px', 'borderWidth':'1px', 'borderColor':'#DDD','fontSize':'12pt'};
