Ruby on rails YUI3上传器+；轨道rjs

我正在尝试将YUI3上传程序用于Rails 2.3.12项目。我已经让它在上传后解析响应。响应是一个RJS文件，呈现一个部分，以更新页面上的元素

当通过正常的非闪存上传运行时，这个RJS可以像预期的那样工作，并且它可以像预期的那样与SWFUpload插件一起工作

在Firefox中，我得到一个错误：

有什么想法吗？

算是解决了。为了这些操作，我放弃了RJ，而是编写了一个ERB模板来输出所需的javascript

RJS助手加上YUI上传器的JS包装和转义都是乱七八糟的——现在我只是在渲染我所需要的东西。

看来，转义特殊角色的几层在几层执行中被绊倒了。冒着陈述显而易见的风险，我会尝试将RJ简化到最低限度，并从那里开始工作。
