时间格式为：2017-12-12 12:00:00在苹果上获取时间戳有兼容性问题
需要转换成2017/12/12 12:00:00 才可以正确获取到时间戳
let u = navigator.userAgent; //判断浏览器型号
let isAndroid = u.indexOf('Android') > -1 || u.indexOf('Adr') > -1; //android终端
let isiOS = !!u.match(/(i[^;]+;( U;)? CPU.+Mac OS X/); //ios终端
if(isiOS){
let time = new Date((v[0].createTime).replace(/-/g,'/')).getTime();
this.timeago=this.getDateDiff(time);
}else{
let time = new Date(v[0].createTime).getTime();
this.timeago=this.getDateDiff(time);
}
判断时间过去了多久
getDateDiff(dateTimeStamp){
let result;
let minute = 1000 * 60;
let hour = minute * 60;
let day = hour * 24;
let halfamonth = day * 15;
let month = day * 30;
let now = new Date().getTime();
let diffValue = now - dateTimeStamp;
if(diffValue < 0){
return;
}
let monthC =diffValue/month;
let weekC =diffValue/(7*day);
let dayC =diffValue/day;
let hourC =diffValue/hour;
let minC =diffValue/minute;
if(monthC>=1){
if(monthC<=12)
result="" + parseInt(monthC) + "月前";
else{
result="" + parseInt(monthC/12) + "年前";
}
}
else if(weekC>=1){
result="" + parseInt(weekC) + "周前";
}
else if(dayC>=1){
result=""+ parseInt(dayC) +"天前";
}
else if(hourC>=1){
result=""+ parseInt(hourC) +"小时前";
}
else if(minC>=1){
result=""+ parseInt(minC) +"分钟前";
}else{
result="刚刚";
}
return result;
},
