您好，感谢您的所有回答。
我的问题是我想在我使用框架 Symfony2 开发的 web 应用程序中使用 jqPlot 库。
以下是我的观点：
<head>

问题是当我渲染我的视图时，虽然当我在“查看源代码”上检查它时图形就在那里，但没有绘制图形。
更新：我只是检查了几次代码，我认为代码没有问题。会不会是 symfony 的问题？Internet 导航器配置问题（我使用的是 Chrome）
UPDATE2：在 Google Chrome 的 javascript 控制台中，我有这些错误消息“未捕获的 ReferenceError: $ is not defined test:21 (anonymous function)”
UPDATE3：这是我在创建的 .html 文件中使用的相同代码，它可以工作，所以我认为问题与 Symfony2 框架有关。我想现在这是一个任何使用过 symfony 并包含 javascript 代码的人都可以轻松回答的问题
