js imitates strtotime() and date() function implementation method in php_javascript skills

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());
}
</script>

I hope this article will be helpful to everyone’s JavaScript programming design.
