篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了3D Banner(jQuery)相关的知识,希望对你有一定的参考价值。
1.这是用面向对象的思想去动态生成banner的简易流程,用到一个javascript框架jQuer;
2.将代码黏贴成html文件,直接用浏览器打开即可;
3.layer属于弹窗提示类插件,可能需要自己手动引入,因为在分成1000分以上时,可能浏览器会被卡死,所以给了一个小小的弹窗提示!
4.代码中有注释,看到的小伙伴可以用chrome或者是火狐浏览器测试一下,每个浏览器解析代码机制不同,会一点差异,不支持IE浏览器。
代码如下:

我们把它分成150分的效果
