Question

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

我尝试了各种各样的事情，比如在IE中使用F12查看控制台;没有错误。如果我查看源代码，我可以正确地看到它应该是HTML。但页面只是空白。如果我使用IE的调试器并在.get()行上放置一个断点，Step Into似乎跳到结束get括号的底部？

CSV文件与.htm位于同一文件夹中，数据如下：

 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。
