问题 I am sporadically getting an OutOfMemoryError: (Heap Size=49187KB, Allocated=41957KB) in one of my apps.

问题 Is it possible to detect once an image has been loaded with jQuery? 回答1: You can use the .load() event handler, like this: $("#myImg").load(function() { alert('I loaded!'); }).attr('src', 'myImage.jpg'); Be sure to attach it before setting the source, or the event may have fired before you attached a handler to listen for it (e.g. loading from cache). If that's not doable (setting the src after binding), be sure to check if it's loaded and fire it yourself, like this: $("#myImg").load
