将时间戳转化为日期格式

代码如下

 export function change(date) {
    //date是整数，否则要parseInt转换
    let time = new Date(date);
    let y = time.getFullYear();
    let m = time.getMonth()+1;
    let d = time.getDate();
    let h = time.getHours();
    let mm = time.getMinutes();
    let s = time.getSeconds();
    return y+'-'+add0(m)+'-'+add0(d)+' '+add0(h)+':'+add0(mm)+':'+add0(s);
}
 function add0(m){return m<10?'0'+m:m }
