The example in this article describes the implementation method of js imitating strtotime() and date() functions in php. Share it with everyone for your reference. The details are as follows:

In js, there are no strtotime() and date() functions like in php, which can directly convert timestamps. Next, we will customize a function to implement the specific timestamp conversion function in js.

function datetime_to_unix(datetime){ 
  var tmp_datetime = datetime.replace(/:/g,'-'); 
  tmp_datetime = tmp_datetime.replace(/ /g,'-'); 
  var arr = tmp_datetime.split("-"); 
  var now = new Date(Date.UTC(arr[0],arr[1]-1,arr[2],arr[3]-8,arr[4],arr[5])); 
  return parseInt(now.getTime()/1000); 
} 
function unix_to_datetime(unix) { 
  var now = new Date(parseInt(unix) * 1000); 
  return now.toLocaleString().replace(/年|月/g, "-").replace(/日/g, " "); 
} 
var datetime = '2012-11-16 10:36:50'; 
var unix = datetime_to_unix(datetime); 
document.write(datetime+' 转换后的时间戳为: '+unix+' 
'); 
var unix = 1353033300; 
var datetime = unix_to_datetime(unix); 
document.write(unix+' 转换后的日期为: '+datetime);

If you want to pop up: 2010-10-20 10:00:00, this format is easy to do

<script>
function getLocalTime(nS) {
  return new Date(parseInt(nS) * 1000).toLocaleString().replace(/年|月/g, "-").replace(/日/g, " "); 
}
alert(getLocalTime(1177824835));
</script>

Complete example

<script type="text/javascript">
var day1 = parseInt(new Date().valueOf()/1000);
var day2 = new Date(day1 * 1000);
function getLocalTime(nS) { 
  return new Date(parseInt(nS) * 1000).toLocaleString().replace(/:d{1,2}$/,' '); 
}
/* 同上面函数 */
function getLocalTimes(nS) { 
  return new Date(parseInt(nS) * 1000).toLocaleString().substr(0,17);
} 
function getLocalFormatTime(nS) { 
 return new Date(parseInt(nS) * 1000).toLocaleString().replace(/年|月/g, "-").replace(/日/g, " ");  
}
document.getElementById("btn1").onclick = function(){
 alert(day1);
}
document.getElementById("btn2").onclick = function(){
 alert(day2.toLocaleString());
}
document.getElementById("btn3").onclick = function(){
 alert( getLocalTime(day1) );
}
document.getElementById("btn4").onclick = function(){
 alert( getLocalFormatTime(day1) );
}
document.getElementById("btn5").onclick = function(){
 alert(day2.getFullYear()+"-"+(day2.getMonth()+1)+"-"+day2.getDate()+" "+day2.getHours()+":"+day2.getMinutes()+":"+day2.getSeconds());
}
