有没有办法扩展Chrome WebKit检查器的元素视图中的所有元素？
有没有办法在clojurescript中访问"this"对象？
我有问题与事件传播,当我换一个图标与锚,并尝试一个handlder连接到锚.如果在处理程序中无法访问"this",我会不时处理触发事件的内部图标,而其他时候会触发锚点.
编辑:
如下所示,这就是这样做的方式.一个例子可能是
(defn my-handler
[e]
(this-as this
(let [data-attr (.data ($ this) "my-attr")]
(log data-attr))))
有没有办法将clojure函数作为字符串返回？我正在制作一些在线文档,我真的希望能够通过某种方式将函数评估为文本来将代码添加到html中.
谢谢
我试图在OSX Lion中与Sinatra和Mustache一起运行.经过大量的谷歌搜索后,我没有进一步解决问题.我很确定它与OSX中的Ruby权限有关,因为错误(下面)从示例config.ru文件的第一行开始(需要'app').该项目在这里(https://github.com/defunkt/mustache-sinatra-example)
这是我的错误
