//yyyy-mm-dd H:i轉化為時間戳 var datetime_to_unix = function(date){ var tmp_datetime = date.replace(/:/g,'-'); tmp_datetime = tmp_datetime.replace(/ /g,'-'); var arr = tmp_datetime.split("-"); var now = new Date(Date.UTC(arr[0],arr[1]-1,arr[2],arr[3]-8,arr[4])); return parseInt(now.getTime()/1000); } //時間戳轉化為當前時間 var unix_to_datetime = function(x,unix) { var date = null; if(unix){ date = new Date(unix); }else { date = new Date; } Y = date.getFullYear() + '-'; M = (date.getMonth()+1 < 10 ? '0'+(date.getMonth()+1) : date.getMonth()+1); D = date.getDate() < 10 ? '0' + date.getDate() + ' ' : date.getDate() + ' '; h = date.getHours() < 10 ? '0' + date.getHours() + ':' : date.getHours() + ':'; m = date.getMinutes() < 10 ? '0' + date.getMinutes() : date.getMinutes(); s = date.getSeconds() < 10 ? '0' + date.getSeconds() : date.getSeconds(); if(x === 1){return (Y+M+'-'+D+h+m);}//2017-09-29 21:30 if(x === 4){return (Y+M+'-'+D+h+"00");}//2017-09-29 21:00 if(x === 2){return (Y+M+'-'+D+"00"+":"+"00");}//2019-09-29 00:00 if(x === 3){return (Y+M+'-'+D);}//2019-09-29 if(x === 5){return (Y+M+'-'+"01");}//2019-09-01 if(x === 6){return (Y+M);}//2019-09 if(x === 7){return (Y+M+'-'+D+h+m+':'+s);}//精確到秒 if(x === 0){//取上一個月 var Y2 = date.getFullYear(); //獲取當前日期的年份 var M2 = parseInt(date.getMonth()); if (M2 === 1) {//如果是1月份,則取上一年的12月份 Y2 = parseInt(Y2) - 1; month2 = 12; } return (Y2+'-'+M2); } };
