下面有以下 HTML/JS(取自 Highcharts 示例),旨在从 CSV 文件加载一些基本数据。但加载 .htm 时,它只是空白。

我尝试过各种方法,例如在 IE 中使用 F12 查看控制台;没有错误。如果我查看源代码,我可以正确地看到应有的 HTML。但该页面只是空白。如果我使用 IE 的调试器并在 .get() 行上放置断点,Step Into 似乎会跳到右 get 括号的底部?

CSV 文件与 .htm 位于同一文件夹中,数据如下所示:

 DateTime,Count
10/11/2016 00:00:00,20
10/12/2016 00:00:00,12
10/13/2016 00:00:00,5

我确认文件末尾没有空行。

HTML/JS:

<!DOCTYPE HTML>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">

<script type="text/javascript">
$(document).ready(function() {
// Get the CSV and create the chart
$.get('count_changes.csv', function (data) {

$('#container').highcharts({
