delayedcljs

A reacl class that delays clazz's state change for delay milliseconds.

Example:

This is a reacl class that implements a text input field that can be used as search field:

 (reacl/defclass search-input this state []
   render
   (dom/letdom [search-input 
                (dom/input {:type "text"
                            :id "search"
                            :onChange #(reacl/send-message! this (.-value (dom/dom-node this search-input)))})]
     (dom/div search-input))
   handle-message
   (fn [data]
     (reacl/return :app-state data)))

Often it is not efficient to actually perform a search and update the search results after every key the user types, but only after the user hasn't type anything in while. The delayed reacl class provides a way to delay the propagatation of the search-field's state change. Here, the search field's update to the application state is published after a delay of 200 milliseconds of inactivity:

 (delayed this search-input 200)

Or, to keep the internal state of delayed and search-input separate from the surrounding application's state, you can embed delayed:

 (delayed this local-state (reacl/pass-through-reaction this) filter-input 200)
A reacl class that delays `clazz`'s state change for `delay`
milliseconds.

Example:

This is a reacl class that implements a text input field that can
be used as search field:

     (reacl/defclass search-input this state []
       render
       (dom/letdom [search-input 
                    (dom/input {:type "text"
                                :id "search"
                                :onChange #(reacl/send-message! this (.-value (dom/dom-node this search-input)))})]
         (dom/div search-input))
       handle-message
       (fn [data]
         (reacl/return :app-state data)))

Often it is not efficient to actually perform a search and update the
search results after every key the user types, but only after the user
hasn't type anything in while.  The `delayed` reacl class provides a
way to delay the propagatation of the `search-field`'s state change.
Here, the search field's update to the application state is published
after a delay of 200 milliseconds of inactivity:

     (delayed this search-input 200)

Or, to keep the internal state of `delayed` and `search-input`
separate from the surrounding application's state, you can embed
`delayed`:

     (delayed this local-state (reacl/pass-through-reaction this) filter-input 200)
