ios中getTime()的兼容性实例代码

   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; },
