JS、jquery实现几分钟前、几小时前、几天前等时间差显示效果的代码实例分享_javascript技巧

//JavaScript函数：
var minute = 1000 * 60;
var hour = minute * 60;
var day = hour * 24;
var halfamonth = day * 15;
var month = day * 30;
function getDateDiff(dateTimeStamp){
var now = new Date().getTime();
var diffValue = now - dateTimeStamp;
if(diffValue < 0){
//若日期不符则弹出窗口告之
//alert("结束日期不能小于开始日期！");
}
var monthC =diffValue/month;
var weekC =diffValue/(7*day);
var dayC =diffValue/day;
var hourC =diffValue/hour;
var minC =diffValue/minute;
if(monthC>=1){
result="发表于" + parseInt(monthC) + "个月前";
}
else if(weekC>=1){
result="发表于" + parseInt(weekC) + "周前";
}
else if(dayC>=1){
result="发表于"+ parseInt(dayC) +"天前";
}
else if(hourC>=1){
result="发表于"+ parseInt(hourC) +"个小时前";
}
else if(minC>=1){
result="发表于"+ parseInt(minC) +"分钟前";
}else
result="刚刚发表";
return result;
}

//js函数代码：字符串转换为时间戳
function getDateTimeStamp(dateStr){
return Date.parse(dateStr.replace(/-/gi,"/"));
}
