js处理时间戳

formatDate(ts) {
    var now = new Date(ts);
    var year = now.getFullYear();
    var month = ((now.getMonth() + 1) < 10) ? ('0' + (now.getMonth() + 1)) : (now.getMonth() + 1);
    var date = (now.getDate() < 10) ? ('0' + now.getDate()) : (now.getDate());
    var hour = (now.getHours() < 10) ? ('0' + now.getHours()) : (now.getHours());
    var minute = (now.getMinutes() < 10) ? ('0' + now.getMinutes()) : (now.getMinutes());
    var second = (now.getSeconds() < 10) ? ('0' + now.getSeconds()) : (now.getSeconds());
    return year + "-" + month + "-" + date + "   " + hour + ":" + minute + ":" + second;
},
