因此,我试图让这个JSFIDLE工作:

它在那里工作得很好

但是,当我转到我的机器并使用代码时(只是为了在进行我自己的更改之前看看它是否工作),它不工作,只需获取灰色div。控制台中没有错误

我的代码顺序如下:

  <script src="https://code.jquery.com/jquery-2.2.2.min.js"></script>
  <script src="http://d3js.org/d3.v2.min.js" charset="utf-8"></script>

然后是div

  <div id="chart"></div>

然后是剧本


我已经尝试过在
$(文档)中进行包装。准备好了
,也尝试过在一个外部文件中进行包装。似乎什么都不管用。我绞尽脑汁想弄明白这一点,任何帮助都将不胜感激
