vue 实现LED数字时钟(开箱即用)

效果图

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:

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
