JS获取系统时间--JavaScript基础
1、网页中实时显示当前时间
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>页面上显示系统时间</title>
</head>
<body onload="showTime()">
当前时间为：<span id="show"></span>
</body>
<script>
function showTime() {
var nowTime = new Date();
var years = nowTime.getFullYear();
var mouths = nowTime.getMonth();
var days = nowTime.getDate();
var hours = nowTime.getHours();
var minites = nowTime.getMinutes();
var seconds = nowTime.getSeconds();
var time = years+"年";
time += (mouths+1)+"月"+days+"日";
time += (hours<10?"0":"")+hours;
time += (minites<10?":0":":") + minites;
time += (seconds<10?":0":":") + seconds;
time += (hours>12)?"PM":"AM";
document.getElementById("show").innerHTML = time;
setTimeout("showTime()",1000);
}
</script>
</html>
