我正在尝试将Google脚本中的变量传递给HtmlOutputFromFile [英] I am trying to pass a variable from my Google Script through to HtmlOutputFromFile

问题描述

我正在尝试创建一个带有下拉列表的输入框，该列表基于从电子表格中提取的2D数组.

I am trying to create an input box with a drop down list, where that list is based on a 2D array pulled from a Spreadsheet.

到目前为止，我的研究告诉我，如果我将HtmlService.createHtmlOutputFromFile存储在一个变量中，则可以设置该变量的属性"，然后将其传递给html. (我看到它专门用于HtmlService.createTemplateFromFile)

My research so far has told me that if i store the HtmlService.createHtmlOutputFromFile in a variable that I can then "set properties" of that variable that will then get passed to the html. (i saw this used specifically with HtmlService.createTemplateFromFile)

//google script code
function selectMonth(){
  var monthTab = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("sheet1");
  var LR = monthTab.getRange("B1").getDataRegion().getLastRow()
  var sNamesArray = monthTab.getRange(1,2,LR,2).getValues()

  var monthBox = HtmlService.createHtmlOutputFromFile('Month Box')
    .setSandboxMode(HtmlService.SandboxMode.IFRAME)
    .setWidth(250)
    .setHeight(50);

//i believe the error to be occurring on this line
  monthBox.mList = sNamesArray

SpreadsheetApp.getUi().showModalDialog(monthBox, 'Student Name List');
};

<!--html code-->
<select id="tabMonth">
  <option disabled selected>Select Month</option>
  <?for(var i=0;i<list.length;i++){ ?>
    <option value=<?mList[i][1]?>><?mList[i][0]?></option>
  <?}?>
</select>

但是每次我尝试运行代码时，我都会收到错误消息: 对象不允许添加或更改属性."

but every time i try and run the code i get the error: "Object does not allow properties to be added or changed."

基于我可以判断出的错误发生在上面指示的行上

based upon what i can tell the error is occurring on the line indicated above

推荐答案

问题:

• 尝试修改HtmlOutput对象，而不是修改HtmlTemplate对象.

Issue:

• Attempting to modify the HtmlOutput object instead of modifying HtmlTemplate object.
• 仅html模板可以使用变量进行修改.修改template并对其求值以返回HtmlOutput
• Only the html template can be modified with variables. Modify the template and evaluate it to return HtmlOutput

var monthBox = HtmlService.createHtmlTemplateFromFile('Month Box');//Type: HtmlTemplate
monthBox.mList = sNamesArray;

monthBox = monthBox.evalate()    //Type: HtmlOutput after evaluation
    .setSandboxMode(HtmlService.SandboxMode.IFRAME)
    .setWidth(250)
    .setHeight(50);
