我有一些从网站下载的jQuery代码，我想让它更容易理解。
任何人都可以帮我把它移到我可以删除部分未使用代码的状态吗？

您可以做的第一件事是通过beautifier运行它。
(function (a) {
var A = function (s, v) {
var f = a.extend({}, a.fn.nivoSlider.defaults, v),
g = {
currentSlide: 0,
currentImage: "",
totalSlides: 0,
randAnim: "",
running: false,
paused: false,
stop: false
},
e = a(s);
e.data("nivo:vars", g);
// etc...
似乎它是nivoSlider的源代码。如果您将上述美化代码与其他已发布的nivoSlider source code进行比较，您可以看到相似性。

这是缩小的代码。由于重命名变量，很难重读。如果您只想阅读代码本身，请将其粘贴到http://www.jsbeautifier.com/
中在此处下载未压缩的代码： http://nivo.dev7studios.com/
答案 2 :(得分：0)
答案 3 :(得分：-1)
对于实际的jQuery库（你包含的代码似乎不是真正的库），下载未缩小版本..它会更有意义
http://code.jquery.com/jquery-1.5.js
至于你所展示的代码，你可以像其他答案所指出的那样使用美化器。
