vue 实现LED数字时钟效果（开箱即用）

Posted in Javascript onDecember 08, 2019

vue 实现LED数字时钟效果（开箱即用） 

实现思路

每一个数字由七个元素构成，即每一个segment元素。0~9 的数字都有自己的构成方式，用数组表示，即digitSegments数组。例如：

vue 实现LED数字时钟效果（开箱即用） 

数字0用数组表示就是[1,2,3,4,5,6]，定时器每隔一秒获取最新时间，然后通过改变透明度将之前的数字消失，显示最新的数字。通过transition展示动态效果。

代码细节

setNumber 方法用来设置数字 ，方法中第一个判断用于清除之前显示的数字，第二个判断用于显示最新的数字，当初始化时间时，会进第二个判断。样式有些丑，可以自己修改，年月日 的显示也可使用 正常的数字显示。

实现代码
