A place to collect small useful Javascript libraries.
When not writing Javascript in the new hotness style of partial reloads, you might end up doing a nifty AJAX POST but then end up running a page refresh because it's easy. Well, Prefresh aims to make it as easy to not do that. Give it a function to load some data, a function to act on that data, and (optionally) some initial data and it will:
- Provide the initial data to the handler function on the first call to
refresh().- If no initial data is provided (or is given a non-true value), it will call the loader function to get the initial data.
- On subsequent calls to
refresh(), it will call the loader.
The loader function will be called with the handler function and the prefetch state (true if the first call to init/refresh,
false otherwise). With this you can call the handler callback yourself from an inline success function in a jQuery.ajax
call, for example.
The second, and more automagic, way to use a loader function is to return the object you would hand to jQuery.ajax from
the loader function. Prefresh will make the call, and pass the results on to the handler function. It'll also call the
success function on the jQuery.ajax parameter object, if it exists.
