js时间戳和日期互转换

1.日期转时间戳

//获取当前时间戳
new Date().getTime()；
//获取固定时间的时间戳
new Date('2018-12-01 12:22').getTime()

2.时间戳转日期

function formatDateTime(timeStamp) { 
    var date = new Date();
    date.setTime(timeStamp * 1000);
    var y = date.getFullYear();    
    var m = date.getMonth() + 1;    
    m = m < 10 ? ('0' + m) : m;    
    var d = date.getDate();    
    d = d < 10 ? ('0' + d) : d;    
    var h = date.getHours();  
    h = h < 10 ? ('0' + h) : h;  
    var minute = date.getMinutes();  
    var second = date.getSeconds();  
    minute = minute < 10 ? ('0' + minute) : minute;    
    second = second < 10 ? ('0' + second) : second;   
    return y + '-' + m + '-' + d+' '+h+':'+minute+':'+second;    
};  
console.log(formatDateTime(1495157126));
