今天少一个Javascript小应用:实现很酷炫的罗盘时钟。它跟我们平时做的时钟有点不一样,正常的都是圆形+数字类型的,今天我们分享的另外一种酷炫的,先看看看效果图吧,如下:

就是就是按照时间去排序的,然后组合成一个时钟。代码如何实现的呢?废话不多少,上DEMO吧。

HTML

<div id="clock"></div>

CSS

<style>
        *{
        margin:0;
        padding:0
        }
        html,body{
        width:100%;
        height:100%;
        background-color:#000;
        overflow:hidden
        }
        #clock{
        position:relative;
        width:100%;
        height:100%;
        background:#000
        }
        .label{
        display:inline-block;
        color:#4d4d4d;
        text-align:center;
        padding:0 5px;
        font-size:19px;
        transition:left 1s,top 1s;
        transform-origin:0% 0%
        }
</style>

JS

JS是核心,主要实现的功能。如下:

<script>
        var monthText=["一月","二月","三月","四月","五月","六月","七月","八月","九月","十月","十一月","十二月"];
        var dayText=["零一号","零二号","零三号","零四号","零五号","零六号","零七号","零八号","零九号","十号","十一号","十二号","十三号","十四号","十五号","十六号","十七号","十八号","十九号","二十号","二十一号","二十二号","二十三号","二十四号","二十五号","二十六号","二十七号","二十八号","二十九号","三十号","三十一号"];
        var weekText=["星期日","星期一","星期二","星期三","星期四","星期五","星期六"];
        var hourText=["零点","零一点","零两点","零三点","零四点","零五点","零六点","零七点","零八点","零九点","零十点","十一点","十二点","十三点","十四点","十五点","十六点","十七点","十八点","十九点","二十点","二十一点","二十二点","二十三点"];
        var minuteText=["零一分","零二分","零三分","零四分","零五分","零六分","零七分","零八分","零九分","零十分","十一分","十二分","十三分","十四分","十五分","十六分","十七分","十八分","十九分","二十分","二十一分","二十二分","二十三分","二十四分","二十五分","二十六分","二十七分","二十八分","二十九分","三十分","三十一分","三十二分","三十三分","三十四分","三十五分","三十六分","三十七分","三十八分","三十九分","四十分","四十一分","四十二分","四十三分","四十四分","四十五分","四十六分","四十七分","四十八分","四十九分","五十分","五十一分","五十二分","五十三分","五十四分","五十五分","五十六分","五十七分","五十八分","五十九分","六十分"];
        var secondsText=["零一秒","零二秒","零三秒","零四秒","零五秒","零六秒","零七秒","零八秒","零九秒","零十秒","十一秒","十二秒","十三秒","十四秒","十五秒","十六秒","十七秒","十八秒","十九秒","二十秒","二十一秒","二十二秒","二十三秒","二十四秒","二十五秒","二十六秒","二十七秒","二十八秒","二十九秒","三十秒","三十一秒","三十二秒","三十三秒","三十四秒","三十五秒","三十六秒","三十七秒","三十八秒","三十九秒","四十秒","四十一秒","四十二秒","四十三秒","四十四秒","四十五秒","四十六秒","四十七秒","四十八秒","四十九秒","五十秒","五十一秒","五十二秒","五十三秒","五十四秒","五十五秒","五十六秒","五十七秒","五十八秒","五十九秒","六十秒"];
