一些常用的可以封装好的方法

1.时间搓转为时间

//时间鹾转换
formatDate(time,num) {
    var datetime = "";
    if (time == "") {
        return false;
    }else{
        var d = new Date();
        d.setTime(time * 1000);
        var year = d.getFullYear();
        var month = d.getMonth() + 1;
        var day = d.getDate();
        var minute = d.getMinutes();
        var hour = d.getHours();
        var second = d.getSeconds();
        if(month < 10){
            month = "0"+month;
        }
        if(day < 10){
            day = "0"+day;
        }
        if(hour < 10){
            hour = "0"+hour;
        }
        if(minute < 10){
            minute = "0"+minute;
        }
        if(second < 10){
            second = "0"+second;
        }
        if (num == 0) {
            datetime = year + '-' + month +'-'+ day ;
        }
        else if (num == 2){
            datetime = month +'月'+ day+'日';
        }else{
            datetime = year + '-' + month +'-'+ day +" "+ hour +":"+ minute +":"+ second;
        }
        return datetime;
    }
},
