Question

$('div').animate({ 'background':'yellow' }, 2000,'linear', function() {

为什么？

来自 jQuery API (http://api.jquery.com/animate/):

All animated properties should be numeric (except as noted below); properties that are non-numeric cannot be animated using basic jQuery functionality. (For example, width, height, or left can be animated but background-color cannot be.) Property values are treated as a number of pixels unless otherwise specified. The units em and % can be specified where applicable.

要设置颜色动画，请使用 jQuery.color 插件:http://plugins.jquery.com/project/color
