This article describes the method of displaying Beijing time in real time by javascript. Share it for your reference. The details are as follows:
Beijing time is displayed in real time on this page. Changing the time zone can also be used to display world time. The code is as follows:
Copy the code as follows:<script type="text/javascript">
Date.prototype.strftime = function(format){
var o = {
"M+" : this.getMonth()+1, //month
"d+" : this.getDate(), //day
"h+" : this.getHours(), //hour
"m+" : this.getMinutes(), //minute
"s+" : this.getSeconds(), //second
"q+" : Math.floor((this.getMonth()+3)/3), //quarter
"S" : this.getMilliseconds() //millisecond
}
if(/(y+)/.test(format)) {
format = format.replace(RegExp.$1, (this.getFullYear()+"").substr(4 - RegExp.$1.length));
}
for(var k in o) {
if(new RegExp("("+ k +")").test(format)) {
format = format.replace(RegExp.$1, RegExp.$1.length==1 ? o[k] : ("00"+ o[k]).substr((""+ o[k]).length));
}
}
return format;
}
function UTCToLocalTimeString(d, format) {
var timeOffsetInHours = (new Date().getTimezoneOffset()/60) + -10;
d.setHours(d.getHours() + timeOffsetInHours);
return d.strftime(format);
}
</script>
<script >
setInterval(function(){var time = UTCToLocalTimeString(new Date(),'yyyy/MM/dd hh:mm:ss');document.getElementById("bjTime").innerHTML = time;},1000);
</script>
<span id="bjTime"></span>
