本文实例讲述了JavaScript实现的浮动层框架用法。分享给大家供大家参考。具体如下：

这是一个JavaScript编写的浮动层框架，作为框架来说，骨干已经完成了。可以实现“类”、“构造函数”、“继承”（木有实现多继承）、“静态方法”、“重载”（木有实现多态），对我来说主要的意义就是，我喜欢这种代码风格，可以非常简单的重用和二次开发。

运行效果截图如下：

P70系列延期，华为新旗舰将在下月发布

3月20日消息，近期博主@数码闲聊站 透露，原定三月份发布的华为新旗舰P70系列延期发布，预计4月份上市。

而博主@定焦数码 爆料，华为的P70系列在定位上已经超过了Mate60，成为了重要的旗舰系列之一。它肩负着重返影像领域顶尖的使命。那么这次P70会带来哪些令人惊艳的创新呢？

根据目前爆料的消息来看，华为P70系列将推出三个版本，其中P70和P70 Pro采用了三角形的摄像头模组设计，而P70 Art则采用了与上一代P60 Art相似的不规则形状设计。这样的外观是否好看见仁见智，但辨识度绝对拉满。
