我对榆树很新(并且总体来说是前端开发),所以我希望我的问题不是太明显,但我想知道如何重用UI框架,如Elm中的Bootstrap 3,包括JS.
更确切地说,我今天的目标是或多或少地复制Bootstrap的Navbar文档中的示例,其中下拉按钮包含在导航栏中.到目前为止,使用Html和Html.Attributes,我能够构建页面并正确设置样式,但实际的下拉行为不起作用:当我点击插入符号按钮时,没有任何反应.我猜这是因为连接到下拉列表的Javascript没有被执行.
现在,我的问题是:
谢谢你们

我目前正在现实生活中使用Bootstrap进行现实生活中的Elm项目,它的工作效果非常好.
我认为你不想通过复制榆树中的东西将它整合到榆树中.根据我的经验,您将始终是当前Bootstrap版本背后的一(或两)个步骤.
尽管设置完成所有设置可能有点挑战,但一旦完成它运行完美无瑕.为了让你前进,我发布了index.html我用来加载Elm应用程序的文件.它是一个带有客户端路由的单页应用程序,这就是我将其发送window.location.pathname到应用程序的原因.它与使用Bootstrap无关.我包括它因为我真的想或多或少地"按原样"发布文件.
基本上我们只是在加载和启动Elm应用程序之前,直接从内容分发网络将Bootstrap CSS和JS加载到浏览器中.

一旦我们启动了Elm应用程序,就像使用Bootstrap的任何其他项目一样,生成Bootstrapified HTML和CSS的简单方式.
为了让您了解如何实现导航栏,这是我在Elm中导航条形码的简单摘录:
-- Navigation bar ------------------------------------------------------------
--
-- TODO: Adapt to more responsive design. Stack navigation in mobile-friendly
-- layout and minimize user/instrument information.
--
-- Page link buttons
pageLinks : Context -> List Html
pageLinks (link, model, _) =
List.map (\p ->
li [ classList [ ("active", model.page == p) ] ]
[ link (pageToRoute p) (pageName p) ]) visiblePages
-- Dropdown menu with available options
dropdownSelectOption : Context -> Html
dropdownSelectOption (_, model, address) =
let
-- Option selection row (displayed in dropdown menu)
iRow i =
let
title_ = case i.macId of
Just macId -> macId -- primarily use macId if available
Nothing -> i.uuid -- otherwise, fallback on using the uuid
-- Determine if the option is selected and/or online/offline
isSelected = isActiveOption model i.uuid
in
li [ title title_ ]
[ a [ href "#", onClick address (SelectOption i.uuid) ]
[ text i.displayName,
span [ classList [("pull-right glyphicon glyphicon-remove-sign status-offline", i.status == Offline),
("pull-right glyphicon glyphicon-ok-sign status-online", i.status == Online),
("pull-right glyphicon glyphicon-question-sign status-unknown", i.status == Unknown)],
title (optionStatusToString i.status)
] [],
span [ classList [("pull-right glyphicon glyphicon-eye-open selected", isSelected)],
title (OptionSelectedTooltip |> t)
] []
]
]
-- Map rows on list of options
iSelectList = List.map iRow model.options
in
li [ class "dropdown", title (OptionSelectTooltip |> t) ]
[ a [ class "dropdown-toggle",
href "#",
attribute "data-toggle" "dropdown",
attribute "role" "button",
attribute "aria-haspopup" "true",
attribute "aria-expanded" "false" ]
[ OptionSelectionMenu |> tt,
span [ class "caret" ] []
],
ul [ class "dropdown-menu dropdown-menu-right" ]
(List.concat [
[ li [ class "dropdown-menu-label" ]
[ span [] [ OptionSelectLabel |> tt ] ],
li [ class "divider", attribute "role" "separator" ] [] ],
iSelectList])
]
-- The complete navigation bar
navigationBar : Context -> Html
navigationBar ctx =
ul [ class "nav nav-pills pull-right" ]
([ (pageLinks ctx),
[ (dropdownSelectOption ctx) ]
] |> List.concat)
很显然,你可以看到我在这个例子中没有包含很多功能(出于IP原因),但它可以让你知道如何去做.(例如,tt函数转换为一个字符串,然后由text它转换.它是一个支持不同语言的翻译模块).
如果你只是将Bootstrap内部保留在Elm之外的JS/CSS空间中,那么这一切都非常简单.根据我的经验,它没有弄乱Elm diffing算法,因为建议可能是一个问题.
祝好运!榆树真的是一个伟大的语言和范例,用于编写前端代码,一旦你绕过它.
