一、日期字符串转时间戳
// 获取当前时间戳(以s为单位)// 第一种方式var timestamps = +new Date();timestamps = timestamps / 1000;// 第二种方式var timestamp = Date.parse(new Date());timestamp = timestamp / 1000;// 第三种方式var date = new Date("-07-10 10:21:12"); //时间对象var str = date.getTime(); //转换成时间戳str = str / 1000;// 获取某个时间格式的时间戳var stringTime = "-07-10 10:21:12";var timestamp2 = Date.parse(new Date(stringTime));timestamp2 = timestamp2 / 1000;
二、时间戳转日期字符串
// 第一种方式 原生的方式 但是不能修改var timestamp3 = 1403058804;var newDate = new Date();newDate.setTime(timestamp3 * 1000);console.log(newDate.toLocaleDateString()); // 6月18日 console.log(newDate.toLocaleString()); // 6月18日 上午10:33:24 console.log(newDate.toLocaleTimeString()); // 上午10:33:24 // 第二种方式：给日期对象原型添加一个方法Date.prototype.format = function(format) {var date = {"M+": this.getMonth() + 1,"d+": this.getDate(),"h+": this.getHours(),"m+": this.getMinutes(),"s+": this.getSeconds(),"q+": Math.floor((this.getMonth() + 3) / 3),"S+": this.getMilliseconds()};if (/(y+)/i.test(format)) {format = format.replace(RegExp.$1, (this.getFullYear() + '').substr(4 - RegExp.$1.length));}for (var k in date) {if (new RegExp("(" + k + ")").test(format)) {format = format.replace(RegExp.$1, RegExp.$1.length == 1 ?date[k] : ("00" + date[k]).substr(("" + date[k]).length));}}return format;}console.log(newDate.format('yyyy-MM-dd h:m:s'));// 第三种方式：函数处理function formatDate(now) {var year = now.getYear();var month = now.getMonth() + 1;var date = now.getDate();var hour = now.getHours();var minute = now.getMinutes();var second = now.getSeconds();return year + "-" + month + "-" + date + " " + hour + ":" + minute + ":" + second;}var d = new Date(1368360620000);console.log(formatDate(d));
