这就是我所拥有的:
(defn view [cursor owner]
(reify
om/IDidMount
(did-mount [_]
(-> (js/$ ".dropdown-toggle")
(.dropdown)))
om/IRender
(render [_]
(dom/div #js {:className "dropdown"}
(dom/button #js {:className "btn btn-default dropdown-toggle"
:type "button"
:id "dropdownMenu1"} "Dropdown" (dom/span #js {:className "caret"}))
(dom/ul #js {:className "dropdown-menu"
:role "menu"
:ariaLabelledby "dropdownMenu1"}
(dom/li #js {:role "presentation"}
(dom/a #js {:role "menuitem"
:tabIndex "-1"
:href "#"} "Action"))
(dom/li #js {:role "presentation"}
(dom/a #js {:role "menuitem"
:tabIndex "-1"
:href "#"} "Another action")))))))
问题在于,一旦打开下拉列表,它就不再隐藏了,因为当它点击它或其他地方时应该是这样。击键也不起作用。我相信这里缺少一些重要的东西,它会是什么?我正在使用bootstrap 3.1.1和jquery 1.11.0。
感谢。

以下是我创建下拉组件的方法:
(defn dropdown [cursor owner {:keys [id text values]}]
(om/component
(html
[:div.dropdown
[:button {:type "button"
:class "btn dropdown-toggle"
:data-toggle "dropdown"
:id id}
text
[:span {:class "caret"}]]
[:ul {:class "dropdown-menu" :role "menu" :aria-labelledby id}
[:li {:role "presentation"}
(for [v values]
[:a {:role "menuitem" :tabIndex "-1" :href "#"} v])]]])))
隐藏它应该的时候。为了清楚起见,我使用jQuery 1.11.1,Bootstrap 3.2.0和sablono,但这不会影响任何内容。我认为您不应该将IDIDMount用于jQuery,因为所有交互都是通过bootstrap的dropdown JavaScript插件(包含在Bootstrap库中)来处理的。

另一种选择是使用我写的Om-Bootstrap库;有一个下拉组件,可以在内部处理所有这种状态。
下拉列表变为:
(:require [om-bootstrap.button :as b])
(b/toolbar
{}
(for [title ["Default" "Primary" "Success" "Info" "Warning" "Danger" "Link"]
:let [style (.toLowerCase title)]]
(b/dropdown {:bs-style style, :title title}
(b/menu-item {:key 1} "Action")
(b/menu-item {:key 2} "Another action")
(b/menu-item {:key 3} "Something else here")
(b/menu-item {:divider? true})
(b/menu-item {:key 4} "Separated link"))))
http://om-bootstrap.herokuapp.com上的文档网站提供了有关如何使用所有这些组件的示例和代码段。
