我正在使用d3.js从Partial.js框架视图中的JSON数据集生成绘图。
以下是视图页面的代码：

<div id="truckDistance">
<!-- div with the plot -->

<div id="tooltip" class="hidden">
<p class="heading">Node ID:
<span id="node_id">word</span>
</p>
<p class="heading">Distance</p>
<p class="indent">

<p class="indent">

当我启动应用程序并尝试使用此视图访问页面时，不会使用d3 Javascript执行javascript代码，因此不会显示绘图。如果我检查代码，而不是让渲染的SVG我只有原生的javascript。
我错过了什么吗？
答案 0 :(得分：0)
我在本地删除了这个，我认为你只是错过了jQuery ready语句的密切关注：
