javascript - D3 图表可以在 jsfiddle 上完美运行，但不能在 localhost 上运行

所以我试图让这个 jsfiddle 工作:

http://jsfiddle.net/davetaz/Xc8nT/

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(只是为了在进行自己的更改之前看看它是否有效)，它不起作用，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>

然后是脚本。

我尝试过将其包装在 $( document ).ready 中，也尝试在外部文件中使用它。似乎什么都不起作用。我正试图解决这个问题，任何帮助将不胜感激。

最佳答案

您的 HTML 页面格式正确吗？以下对我来说效果很好:

<html>

<head>
<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>

<style>
#chart {
  width: 500px;
  height: 400px;
  background: #bbb;
  font-size: 10px;
}

text {
  pointer-events: none;
}

.grandparent text {
  font-weight: bold;
  font-size: 16px;
}

rect {
  fill: none;
  stroke: #fff;
}

rect.parent,
.grandparent rect {
  stroke-width: 2px;
}
.grandparent rect {
  fill: #fff;
}

.children rect.parent,
.grandparent rect {
  cursor: pointer;
}

rect.parent {
  pointer-events: all;
}

.children:hover rect.child,
.grandparent:hover rect {
  fill: #aaa;
}
</style>
</head>

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