js获取当前毫秒值
var timestamp = new Date().getTime();
js比较时间大小:可以直接比较
if(date2==date2){}
js获取当前时间、js时间戳转日期
//获取时间的方法、参数一为加几天、参数二 :1为年月日、2为年月日时分秒、3为时分------------------------------------------------------------------------------------ function gettime(d,y){ var tm= new Date().getTime(); var now = new Date(24*60*60*1000*d+tm); var year = now.getFullYear(); //年 var month = now.getMonth() + 1; //月 if(month < 10){ month= "0"+month; } var day= now.getDate(); //日 if(day < 10){ day= "0"+day; } var hour = now.getHours(); //小时 if(hour < 10){ hour= "0"+hour; } var minute = now.getMinutes(); //分钟 if(minute < 10){ minute= "0"+minute; } if(y==1){ return year+'-'+month+'-'+day; }else if(y==2){ return year+'-'+month+'-'+day+' '+hour+':'+minute+':00'; }else if(y==3){ return ""+hour+minute; } }
