唯一重要的部分是下划线的模板不工作。这是说,线上的'_':_.each(items, function(item)
是未定义的。这是为什么发生?我试着将包含下划线的脚本移动到页面的顶部,这没有帮助。
哦,我想我明白了为什么它这样做......所以我用ExpressJS与和的NodeJS表达是使用EJS渲染引擎。所以我认为当我使用<% %>时,它认为我正在访问来自嵌入式JavaScript的数据。你认为这是吗?它在服务器端而不是客户端出现错误 – 2013-05-14 05:45:02
@MattHintzke:是的,这听起来似乎合理。看看[这个问题](http://stackoverflow.com/q/9021587)。 – icktoofay 2013-05-14 06:00:39
你是老板。这绝对是为什么 – 2013-05-14 06:17:52
