我试图创建没有任何外部插件的jQuery颜色动画.到目前为止,我可以设法用jQuery-ui做到这一点,但我想用纯jQuery animate()学习这种方式
有没有可能用更少的代码和1.8上没有任何外部jQuery插件来做到这一点？
Here is jsFiddle sample with jQuery 1.7.2 and ui
jQuery的：
var Text = $('h1');
var Box = $('.Box');
Text.click(function() {
Text.animate({'color':'#f00'},600)
.delay(200).animate({'color':'#ff0'},600)
.delay(200).animate({'color':'#000'},600);
});
Box.click(function() {
Box.animate({'background-color':'#f00'},600)
.delay(200).animate({'background-color':'#ff0'},600)
.delay(200).animate({'background-color':'#000'},600);
});
解决方法
你问了更少的代码,所以这是我用
Google Closure Compiler缩小的
relevant code：

在没有gzip或其他压缩的情况下,它在UTF8中约为7kb,并且允许您像以前使用jQuery UI一样动画颜色.这意味着,它允许您在保持相同代码的同时删除jQuery UI.
我还建议您更多地优先考虑您的开发时间.第一次加载时7kb对任何最终用户都不会有明显的变化,甚至不会拨号.这就是为什么我认为重构这是浪费时间的原因.没有必要花费数小时/天重新发明轮子. =]
