javascript - 数组不能在数据表中使用

我尝试通过使用带有数组的数据表来制作表格，但不知何故它没有在我的 html 文件上显示该表格。该数组在我的 gs 文件中定义，如下面的代码所示。

这是一项简单的工作，但我仍然不确定它出了什么问题。

var ssId = 'xxxxxxxxxxxxx';
var ss = SpreadsheetApp.openById(ssId);
var indexPage_sheetName = 'xxxxxxxx';
var valuesFromIndexPage = ss.getSheetByName(indexPage_sheetName).getDataRange().getValues();//array of 850rows×15cols
valuesFromIndexPage.shift();

function getData() {
  $(document).ready(function(){
    $("#foo-table").DataTable({
      data: valuesFromIndexPage
    });
  }); 
}

<html>
<head>
<script src="//ajax.aspnetcdn.com/ajax/jquery/jquery-1.9.1.js"></script>
<link rel="stylesheet" href="https://cdn.datatables.net/1.10.20/css/jquery.dataTables.min.css"/> 
<script src="https://cdn.datatables.net/1.10.20/js/jquery.dataTables.min.js"></script>

<body>
<table id="foo-table" class="display" width="100%"></table>
</body>
</head>
</html>

@ZektorH 这是运行我的代码的控制台日志。

userCodeAppPanel:9 Uncaught TypeError: Cannot read property 'slice' of null

我再次查看了我的数据，发现console.log上的数据变成了空(但是当我在Logger.log上看到它时它有数据)。我正在发布我所做的事情并在下面得到。

function getData() {
  Logger.log(valuesFromIndexPage); //the array is in valuesFromIndexPage
  return valuesFromIndexPage;
}

        function initializeTable(data) {
        console.log(data); //it returns null here...
            var aDataSet = data.slice(1);

来自 Logger.log 的日志

[19-10-31 09:47:00:116 JST] [[ID、案件名称、......

@ZektorH 这些是没有数据的完整代码。

代码.gs

var ssId = 'xxxxxxxxxxxxxxxxxxxxxxxxx';
var ss = SpreadsheetApp.openById(ssId);

var indexPage_sheetName = 'xxxxxxxxxxxxxx';
var valuesFromIndexPage = ss.getSheetByName(indexPage_sheetName).getDataRange().getValues();


function createSidebar() {
SpreadsheetApp.getUi().showSidebar(HtmlService.createHtmlOutputFromFile('index').setTitle('My custom sidebar').setWidth(300))
}

function getData() {
  return valuesFromIndexPage;
}



function doGet(e) {
      return HtmlService.createTemplateFromFile('index').evaluate().setTitle('title');
}

最佳答案

用 dataTable 中键的列来更改表头，并在 $("#foo 处更改 $("#foo-table").DataTable -table").dataTable

var valuesFromIndexPage=[{"free-text-c1":"free-text-r1","c2":"r1","c3":"r1","c4":"r1","c5":"r1","c6":"r1","c7":"r1","c8":"r1","c9":"free-text-r1","c10":"free-text-r1"},{"free-text-c1":"free-text-r2","c2":"r2","c3":"r2","c4":"r2","c5":"r2","c6":"r2","c7":"r2","c8":"r2","c9":"free-text-r2","c10":"free-text-r2"}];

valuesFromIndexPage.shift();

function getData() {
  $(document).ready(function(){
    $("#foo-table").dataTable({
      destroy: true,
      scrollX: true,
      data: valuesFromIndexPage,
      columns: _.keys(valuesFromIndexPage[0]).map((key) => { return { "title": key, "data": key } })
    });
  }); 
}
