前端js转换时间戳为时间类型显示

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