本篇文章给大家分享的是关于JS实现实时显示时间,有感兴趣的朋友可以看一看,有需要帮助的朋友也可以参考一下
在之前的项目中有做到需要在网页中实时显示当前时间,实现的效果如图所示:
1. html结构
<p class="col-xs-12 col-sm-6"> <i class="fa fa-plus-square-o" aria-hidden="true"></i> <span id="current-time"></span> </p>
2. JS
/*实时显示时间*/ function showtime){ var today,hour,second,minute,year,month,date; var strDate ; today=new Date); var n_day = today.getDay); switch n_day){ case 0:{ strDate = "星期日" }break; case 1:{ strDate = "星期一" }break; case 2:{ strDate ="星期二" }break; case 3:{ strDate = "星期三" }break; case 4:{ strDate = "星期四" }break; case 5:{ strDate = "星期五" }break; case 6:{ strDate = "星期六" }break; case 7:{ strDate = "星期日" }break; } year = today.getFullYear); month = today.getMonth)+1; date = today.getDate); hour = today.getHours); minute =today.getMinutes); second = today.getSeconds); if month >= 1 && month <= 9) { month = "0" + month; } if date >= 0 && date <= 9) { date = "0" + date; } if hour >= 0 && hour <= 9) { hour = "0" + hour; } if minute >= 0 && minute <= 9) { minute = "0" + minute; } if second >= 0 && second <= 9) { second = "0" + second; } document.getElementById'current-time').innerHTML ="当前时间:"+ year + "年" + month + "月" + date + "日" +" "+ strDate +" " + hour + ":" + minute + ":" + second; //显示时间 setTimeout"showtime);", 1000); //设定函数自动执行时间为 1000 ms1 s) }
