1、获取当前时间
var myDate = new Date();
2、获取时间中的年月日时分秒
myDate.getYear(); // 获取当前年份(2位) myDate.getFullYear(); // 获取完整的年份(4位,1970-????) myDate.getMonth(); // 获取当前月份(0-11,0代表1月) myDate.getDate(); // 获取当前日(1-31) myDate.getDay(); // 获取当前星期X(0-6,0代表星期天) myDate.getTime(); // 获取当前时间(从1970.1.1开始的毫秒数) myDate.getHours(); // 获取当前小时数(0-23) myDate.getMinutes(); // 获取当前分钟数(0-59) myDate.getSeconds(); // 获取当前秒数(0-59) myDate.getMilliseconds(); // 获取当前毫秒数(0-999) myDate.toLocaleDateString(); // 获取当前日期 var mytime=myDate.toLocaleTimeString(); // 获取当前时间 myDate.toLocaleString( ); // 获取日期与时间
3、时间的格式化
// 对Date的扩展,将 Date 转化为指定格式的String // 月(M)、日(d)、小时(h)、分(m)、秒(s)、季度(q) 可以用 1-2 个占位符, // 年(y)可以用 1-4 个占位符,毫秒(S)只能用 1 个占位符(是 1-3 位的数字) // 例子: // (new Date()).Format("yyyy-MM-dd hh:mm:ss.S") ==> 2006-07-02 08:09:04.423 // (new Date()).Format("yyyy-M-d h:m:s.S") ==> 2006-7-2 8:9:4.18 Date.prototype.Format = function (fmt) { // author: meizz var o = { "M+": this.getMonth() + 1, // 月份 "d+": this.getDate(), // 日 "h+": this.getHours(), // 小时 "m+": this.getMinutes(), // 分 "s+": this.getSeconds(), // 秒 "q+": Math.floor((this.getMonth() + 3) / 3), // 季度 "S": this.getMilliseconds() // 毫秒 }; if (/(y+)/.test(fmt)) fmt = fmt.replace(RegExp.$1, (this.getFullYear() + "").substr(4 - RegExp.$1.length)); for (var k in o) if (new RegExp("(" + k + ")").test(fmt)) fmt = fmt.replace(RegExp.$1, (RegExp.$1.length == 1) ? (o[k]) : (("00" + o[k]).substr(("" + o[k]).length))); return fmt; }
调用:
var time1 = new Date().Format("yyyy-MM-dd"); var time2 = new Date().Format("yyyy-MM-dd hh:mm:ss");

JavaScript core data types are consistent in browsers and Node.js, but are handled differently from the extra types. 1) The global object is window in the browser and global in Node.js. 2) Node.js' unique Buffer object, used to process binary data. 3) There are also differences in performance and time processing, and the code needs to be adjusted according to the environment.

The main difference between Python and JavaScript is the type system and application scenarios. 1. Python uses dynamic types, suitable for scientific computing and data analysis. 2. JavaScript adopts weak types and is widely used in front-end and full-stack development. The two have their own advantages in asynchronous programming and performance optimization, and should be decided according to project requirements when choosing.

Whether to choose Python or JavaScript depends on the project type: 1) Choose Python for data science and automation tasks; 2) Choose JavaScript for front-end and full-stack development. Python is favored for its powerful library in data processing and automation, while JavaScript is indispensable for its advantages in web interaction and full-stack development.

Python and JavaScript each have their own advantages, and the choice depends on project needs and personal preferences. 1. Python is easy to learn, with concise syntax, suitable for data science and back-end development, but has a slow execution speed. 2. JavaScript is everywhere in front-end development and has strong asynchronous programming capabilities. Node.js makes it suitable for full-stack development, but the syntax may be complex and error-prone.

JavaScript can be used for front-end and back-end development. The front-end enhances the user experience through DOM operations, and the back-end handles server tasks through Node.js. 1. Front-end example: Change the content of the web page text. 2. Backend example: Create a Node.js server.

Choosing Python or JavaScript should be based on career development, learning curve and ecosystem: 1) Career development: Python is suitable for data science and back-end development, while JavaScript is suitable for front-end and full-stack development. 2) Learning curve: Python syntax is concise and suitable for beginners; JavaScript syntax is flexible. 3) Ecosystem: Python has rich scientific computing libraries, and JavaScript has a powerful front-end framework.
