问题
I'm working on a script that waits for content to load in a hidden div before activating a thumbnail that points to it.
$('#preload img:first-child') .bind('load',activateThumb) .each(function(){ if(this.complete || this.complete===undefined) $(this).load()});
The each part triggers the load() event for images in the cache. I had to add it in order to make the page work in some browsers that don't fire load() on cached images.
There is also a plugin here that does the same thing essentially, by triggering the load event not "manually" but by resetting the src attribute.
From a programming standpoint, which is the more graceful solution?
回答1:
Resetting the src attribute to fire the load handler seems like a bit of a hack (based on my knowledge). Unless the author of the plugin has some special reason to do that, or knows something we don't, I would stick with your method of manually triggering load.
回答2:
The plugin event.special.load, which is mentioned in the jquery load-event documentation, solves that in a similar way.
