- = DecodeTarget [MisoString]
- | DecodeTargets [[MisoString]]

Decoder
Decoder data type for parsing events
data DecodeTarget Source #
Data type representing path (consisting of field names) within event object, where a decoder should be applied.
Constructors
| DecodeTarget [MisoString] | Specify single path within Event object, where a decoder should be applied. |
| DecodeTargets [[MisoString]] | Specify multiple paths withing Event object, where decoding should be attempted. The first path where decoding suceeds is the one taken. |
Instances
| ToJSVal DecodeTarget Source # | |
Defined in Miso.Event.Decoder Methods toJSVal :: DecodeTarget -> IO JSVal Source # toJSValListOf :: [DecodeTarget] -> IO JSVal Source # | |
at :: [MisoString] -> (Value -> Parser a) -> Decoder a Source #
Smart constructor for building a Decoder.
Decoders
emptyDecoder :: Decoder () Source #
Empty decoder for use with events like "click" that do not return any meaningful values
keycodeDecoder :: Decoder KeyCode Source #
Retrieves either "keyCode", "which" or "charCode" field in Decoder
keyInfoDecoder :: Decoder KeyInfo Source #
Retrieves either "keyCode", "which" or "charCode" field in Decoder, along with shift, ctrl, meta and alt.
checkedDecoder :: Decoder Checked Source #
Retrieves "checked" field in Decoder
valueDecoder :: Decoder MisoString Source #
Retrieves "value" field in Decoder
