不知何故无法让javascript运行：

我正在尝试使用 rails 3.2.2、Heroku、Cedar 堆栈。该应用程序在本地运行良好，并且似乎可以很好地部署到 Heroku，但 javascript 拒绝运行。这个线程似乎涵盖了一个类似的问题，但最终没有一个好的解决方案，所以我想我会再试一次 javascript 没有在使用 rails 3.1 的 heroku 上运行

我已将我的 javascript 精简到最低限度，如下所示。虽然我没有显示 heroku 部署日志，但它看起来很好（预编译通过等）。我留下的最小 javascript 做了两件事：在表单上按下 enter 时发出警报（想要测试所有 javascript 而不仅仅是 jQuery-UI 不起作用）和其他两个函数支持 jQuery-UI

资产管道编译过程看起来不错，即我的 js/css 在浏览器 html 链接中可用，我查看了 firebug，当我尝试触发 javascript 时似乎没有任何反应（尽管我不是专业的 firebug 用户...... )

有任何想法吗？

谢谢！

我发现了我的问题。我的 app/assets/javascripts/ 文件夹中有一些其他文件（script.aculo.us 文件（controls.js、dragdrop.js、effects.js）和prototype.js（程序上一次迭代的剩余部分）通过 //= require_tree . 调用与 application.js 一起包含在资产管道中。sciprt.aculo.us 文件似乎把事情搞砸了

我现在已经设法让我的程序正常工作。我假设我不再需要 script.aculo.us（与 jquery-ui 类似的东西）也不需要prototype.js（现在使用 jquery），我错了吗？

Dogbert 感谢您的帮助。
