Is there some way in yesod-0.9.3 to convert Json
to Html
to include it into <script/>
tag?
Using Yesod.Json
and Data.Aeson
I can get the value of a Json
type, which I want to use as the value of a variable introduced in a <script>
tag, that is, not to return RepJson
, but to include it as a part of RepHtml
.
Using fully qualified names...
let txtVal = Data.Text.Lazy.Encoding.decodeUtf8 $ Data.Aeson.encode jsonVal
then, inside your hamlet:
<script>
var v = #{txtVal}
Note that this is a bit dangerous in that it doesn't check that the encoding was successful. Look at the Data.Text.Encoding
module for more info.
