preloadImages 介绍
preloadImages makes it easy to preload any image, or a list of images. Just
call $.preloadImages(['myimage1.jpg', 'myimage2.jpg']); and it’ll do all the
work for you - preloading one image at a time. This is controlled via a queue,
so images at the start of the queue are preloaded first.
normal usage:
Add to end of queue and start preloading.
$.preloadImages(['1.jpg', '2.jpg', '3.jpg']);
Add:
Add to end of queue, but don’t start preloading.
$.preloadImages.add(['1.jpg', '2.jpg', '3.jpg']);
Prepend:
Prepend to start of queue, but don’t start preloading.
$.preloadImages.prepend(['1.jpg', '2.jpg', '3.jpg']);
Clear:
Clear the queue.
$.preloadImages.clear();
Stop:
Stop processing the queue, but don’t clear it.
$.preloadImages.stop();
Start:
Start processing the queue.
$.preloadImages.start();
Direct manupulation
Directly manipulate the queue as a normal array of image URLs.
