最近更新在x前在JavaScript中

Question

现在我正在使用livestamp.js和moment.js显示页面更新/刷新前x时间前。但是，在没有使用其他js库的情况下，是否可以在普通的js中实现相同的功能。

Answer 1

var date = new Date(); 
 
var finaltime = timeSince(date); 
 
setInterval(function(){ 
 
    document.getElementsByTagName('span')[0].innerHTML = timeSince(date); 
 
},30000); 
 
document.getElementsByTagName('span')[0].innerHTML = timeSince(date); 
 

 
function timeSince(date) { 
 
    var seconds = Math.floor((new Date() - date)/1000); 
 
    var interval = Math.floor(seconds/31536000); 
 

 
    if (interval > 1) { 
 
    return interval + " years"; 
 
    } 
 
    interval = Math.floor(seconds/2592000); 
 
    if (interval > 1) { 
 
    return interval + " months"; 
 
    } 
 
    interval = Math.floor(seconds/86400); 
 
    if (interval > 1) { 
 
    return interval + " days"; 
 
    } 
 
    interval = Math.floor(seconds/3600); 
 
    if (interval > 1) { 
 
    return interval + " hours"; 
 
    } 
 
    interval = Math.floor(seconds/60); 
 
    if (interval >= 1) { 
 
    return interval + " minutes"; 
 
    } 
 
    return Math.floor(seconds) + " seconds"; 
 
}
