前端处理时间为几天前

export function timeFormat(date) {
    let myDate = new Date(date);
    let time = myDate.getFullYear() + '/' + (myDate.getMonth() + 1) + '/' + (myDate.getDate()) + ' ' + myDate.getHours() + ':' + myDate.getMinutes() + ':' + myDate.getSeconds();
    let timestamp = Date.parse(time) - (28 * 3600000);
    var mistiming = Math.round((Date.now() - timestamp) / 1000);
    var arrr = ['年', '个月', '周', '天', '小时', '分钟', '秒'];
    var arrn = [31536000, 2592000, 604800, 86400, 3600, 60, 1];
    for (var i = 0; i < arrn.length; i++) {
        var inm = Math.floor(mistiming / arrn[i]);
        if (inm != 0) {
            return inm + arrr[i] + '前';
        }
    }
}
