JS Calendar Recommendation_Time and Date
I wrote a calendar two years ago, but the compatibility was not good. I re-wrote it this time.
Compatible with multiple browsers
I learned a lot about it, especially about W3C standardization.
For example, FF and IE have different understandings of the box model
box.style{width:100;border 1px;}
ie understands it as box.width = 100
ff understands it as box.width = 100 1*2 = 102
You can use this method to allow both browsers to browse normally
box.style{width:100!important; width /**/:120px;border 1px;}
Note width (space)/**/ Download this file
/***********************
* 创建对象 var c = new Calendar("c"); document.write(c);
* 调用方法 c.show(arg1,arg2,arg3)
* 参数1: 文本输入框(必填). 如 onfocus="c.show(this)";
* 参数2: 按钮或其它可用单击事件的HTML元素(如果使用按钮方式则必填).
如 onclick="c.show(this,c.getObjById(*))" *=文本输入框名称
* 参数3: 如果没有文本框没有值则使用该值初始化日历(选填).
如 onfocus="c.show(this,'2006-01-01')
* 注: 参数顺序不分先后. MSIE6/Opera8/FireFox1.5 下测试通过

JavaScript is the cornerstone of modern web development, and its main functions include event-driven programming, dynamic content generation and asynchronous programming. 1) Event-driven programming allows web pages to change dynamically according to user operations. 2) Dynamic content generation allows page content to be adjusted according to conditions. 3) Asynchronous programming ensures that the user interface is not blocked. JavaScript is widely used in web interaction, single-page application and server-side development, greatly improving the flexibility of user experience and cross-platform development.

There is no absolute salary for Python and JavaScript developers, depending on skills and industry needs. 1. Python may be paid more in data science and machine learning. 2. JavaScript has great demand in front-end and full-stack development, and its salary is also considerable. 3. Influencing factors include experience, geographical location, company size and specific skills.

Learning JavaScript is not difficult, but it is challenging. 1) Understand basic concepts such as variables, data types, functions, etc. 2) Master asynchronous programming and implement it through event loops. 3) Use DOM operations and Promise to handle asynchronous requests. 4) Avoid common mistakes and use debugging techniques. 5) Optimize performance and follow best practices.
