haskell - Threepenny-GUI:拖放 - 访问 DragData

Question

我目前正在努力访问 DragData on UI.drop 时拖动元素的叫做。我有这样的事情:

tile <- UI.new
    # set UI.draggable True
    # set UI.dragData (show player)

field <- UI.new
    # set UI.droppable True

on UI.drop field $ \_ -> do
    -- How to receive the DragData here?

有人可以帮助我吗？提前致谢!

你好，

我知道了:

on UI.drop field $ \dragData -> do
    d <- read dragData

也许它可以帮助别人;)
