First attempt at lazy loading (deferring the load of embedded YouTube videos) - how can I do this more gracefully?

阅读更多关于 First attempt at lazy loading (deferring the load of embedded YouTube videos) - how can I do this more gracefully?

问题 Yesterday I decided to improve the way my website loads YouTube videos by only embedding them when a user requests them. Sometimes a page could have as many as 30 videos on, and this would take a long time to load. This is the first time I've attempted a "lazy loading" method of anything, and I figured it would be well worth asking: What can I do to improve on this? How can I make it a bit more graceful? Does this completely miss the point of deferred loading? JSFiddle. Ignore the styling as

new to twisted and just trying some deferred stuff out. I have the following code that makes up a list of 100 deferred calls - each waiting a random time and returning a value. That list the prints the results and finally terminates the reactor. However, I'm pretty sure the way I'm stopping the reactor is probably... not great. __author__ = 'Charlie' from twisted.internet import defer, reactor import random def getDummyData(x): """returns a deferred object that will have a value in some random seconds sets up a callLater on the reactor to trgger the callback of d""" d = defer.Deferred() pause

How to tell when multiple functions have completed with jQuery deferred

阅读更多关于 How to tell when multiple functions have completed with jQuery deferred

I have 3 functions which handle data pulled in from AJAX, they update the page after the ajax function is called. When the AJAX function is called I show a loader, I want to hide the loader after the AJAX has completed and the functions have completed. How can I use deferred with when and then in jQuery to test once all 3 function are completed. Here is my AJAX code, this hides the loader on AJAX success at the moment, ideally this would be after the 3 functions have been completed / were successful. The 3 functions receive data to process and display on the page, they are not AJAX functions.

I would like to do just: var members_deferr = $.get_members(); members_deferr.done(function() { ... }); One idea is to check type of returned value, but its not very nice. Second
