我正在编写一个简单的应用程序,它会放置一个突出显示语法的代码块。现在我正在使用highlightjs对我的语法高亮显示。
为什么我的highlightBlock
来电不在这里工作?
对于细心的读者:我选择Model
和Msg
是完全荒谬的,因为我现在并没有真正使用它们。
import Html exposing (..)
import Html.App as Html
import Html.Attributes exposing (..)
main =
Html.program
{ init = init
, view = view
, update = update
, subscriptions = subscriptions
}
-- Model
type alias Model = { state: Int }
init : (Model, Cmd Msg)
init = (Model 1, Cmd.none)
-- view
view : Model -> Html Msg
view model = div [ ] [ codesample ]
codesample : Html Msg
codesample = pre [ myStyle ] [ code [] [ Html.text thisCode ] ]
myStyle : Html.Attribute Msg
myStyle = Html.Attributes.style [("background-color", "#F0F0F0"), ("width", "500px")]
thisCode : String
thisCode = """
import Html exposing (..)
import Html.App as Html
import Html.Events exposing (..)
import Random
import Svg exposing (..)
main =
Html.program
{ init = init
, view = view
, update = update
, subscriptions = subscriptions
}
"""
-- update
type Msg
= Roll | NewFace Int
update : Msg -> Model -> (Model, Cmd Msg)
update msg model = ( model , Cmd.none )
-- subscriptions
subscriptions : Model -> Sub Msg
subscriptions model = Sub.none
我打电话给highlightjs
后,我已经超出了纯榆树的范围。我下载了Elm语法高亮包并按如下方式调用库但没有...我怀疑端口是必要的(如Slack所述)
<html>
<head>
<link rel="stylesheet" href="styles/solarized-dark.css">
<script src="highlight.pack.js"></script>
</head>
<body>
<div id="my-elm-block"></div>
<script src="block.js"></script>
<script>
var node = document.getElementById("my-elm-block");
var app = Elm.Main.embed(node);
hljs.highlightBlock(node);
</script>
</body>
</html>
答案 0 :(得分:0)
出于某种原因,在调用embed
之后直接调用Elm生成的DOM上的函数不起作用,但是如果你将它包装在一个很小的超时中,它就会这样做。将您的高亮线更改为:
setTimeout(function() { hljs.highlightBlock(node); }, 1);
我不得不多次使用这个黑客并且没有问题。
