ELM:当我单击按钮时,Onclick 按钮将 HTML 消息中的特定字符串移植到 JS
ELM : Onlick button to port the particular string in HTML message to JS when i click the button
我有模型
type alias Model =
{
url : String
, devices : List Device
, input : String
, isFilter : Bool
, deviceSuggestion : Maybe Device
}
type alias Device =
{
status : String
, license_plate : String
, device_id : String
}
下面是我的渲染视图,我想获取 device_id
并移植到 JS
renderPost : Device -> Html Msg
renderPost devices =
div []
[
[ text "Device_id : "
, button [ onClick PortDeviceID ] [ text (Debug.toString devices.device_id) ]
, pre [] [ text "device_model : " , text (Debug.toString devices.device_model) ]
, pre [] [ text "license_plate : " , text (Debug.toString devices.license_plate) ]
]
renderPosts : Model -> Html Msg
renderPosts model =
([ text "Device List" ] ++ List.map (\device -> renderPost device) model.devices)
我的更新在这里。我不知道如何获取文本,因为 devices.device_id
来自 json 文件
PortDeviceID ->
( { model | deviceID = "" }, //port device_id --> not working)
GotResult result ->
case result of
Ok devices ->
( { model | devices = devices }, portDevice devices ) // this give full list
我想这样做,当我单击按钮时,我可以将特定的 device_id
移植到 JS。问题是它在 Device -> Html Msg format
中,所以我卡住了,哈哈。有什么想法吗?感谢您的帮助!
这里破案了,
在 View 中,我喜欢下面,实例化 devices.device_id
renderPost : Device -> Html Msg
renderPost devices =
div []
[
[ text "Device_id : "
, button [ onClick (PortDeviceID devices.device_id)] [ text (Debug.toString devices.device_id) ]
然后在更新中,同样让 portDeviceID String
PortDeviceID deviceID->
( { model | deviceID = "" }, portDeviceID deviceID )
无论如何感谢 Jack Leow 的帮助
