日期时间转换秒数或者秒数转换日期和时间，在前端页面需要的是日期和时间，而后端保存一般需要秒数，在比较时间前后时，也需要秒数的比较，以下是参考代码：

// 把秒数转换为日期和时间
    	function changeTime(time){ 
    		var date = new Date(time*1000);
    		
    		var hour = date.getHours();
    		var minute = date.getMinutes();
    		var second = date.getSeconds();
    
    		return date.toLocaleDateString().replace(/\//g,'-')+' '+hour+':'+minute+':'+second;
    	}
    	
    	function formatTime(time, type, format){ 
    	  if(!time) return '';
    	  if(type == 'seconds') time = parseInt(time+'000');
    	  if(type == 'milliseconds') time = parseInt(time);
    	  
    	  var DateTime = new Date(time);
    	  var year = DateTime.getFullYear();
    	  var month = prevZero(DateTime.getMonth()+1, 2);
    	  var date = prevZero(DateTime.getDate(), 2);
    	  var hours = prevZero(DateTime.getHours(), 2);
    	  var minutes = prevZero(DateTime.getMinutes(), 2); 
    	  var seconds = prevZero(DateTime.getSeconds(), 2); 
    	
    	  time = format.replace(/y/g, year);
    	  time = time.replace(/m/g, month);
    	  time = time.replace(/d/g, date);
    	  time = time.replace(/h/g, hours);
    	  time = time.replace(/i/g, minutes);
    	  time = time.replace(/s/g, seconds);
    	  return time;
    	}
    	// 前导0
    	function prevZero(num, pos){ 
    	  num = num+'';
    	  var len = pos - num.length;
    	  for(var i=0; i<len; i++){ 
    	    num = '0'+num;
    	  }
    	  return num;
    	}
    
    	// 把日期和时间转换为秒数
    	function changeDate(date){ 
    		var time = new Date(date.replace(/-/g, '/'))
    			time = Math.ceil(time.getTime() / 1000)
    		return time;
    	}
    
    	// 获取时间差
    	function hasTime(time1, time2, type, format){ 
    	  if(!time1 || !time2) return '';
    	  if(type == 'seconds'){ 
    	    time1 = parseInt(time1+'000');
    	    time2 = parseInt(time2+'000');
    	  }
    	  if(type == 'milliseconds'){ 
    	    time1 = parseInt(time1);
    	    time2 = parseInt(time2);
    	  }
    	  var time = time1 - time2;
    	
    	  var year = parseInt(time/(1000*60*60*24*365));
    	  time = time - year*(1000*60*60*24*365);
    	  var month = parseInt(time/(1000*60*60*24*30));
    	  time = time - month*(1000*60*60*24*30);
    	  var date = parseInt(time/(1000*60*60*24));
    	  time = time - date*(1000*60*60*24);
    	  var hours = parseInt(time/(1000*60*60));
    	  time = time - hours*(1000*60*60);
    	  var minutes = parseInt(time/(1000*60));
    	  time = time - minutes*(1000*60);
    	  var seconds = parseInt(time/1000);
    	
    	  time = format.replace(/y/g, year);
    	  time = time.replace(/m/g, month);
    	  time = time.replace(/d/g, date);
    	  time = time.replace(/h/g, hours);
    	  time = time.replace(/i/g, minutes);
    	  time = time.replace(/s/g, seconds);
    	  return time;
    	}
