JS Calendar Recommendation_Time and Date

May 16, 2016 pm 07:23 PM

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)/**/

Copy the code The code is as follows:

/*********************** 

* 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

Demystifying JavaScript: What It Does and Why It Matters Demystifying JavaScript: What It Does and Why It Matters Apr 09, 2025 am 12:07 AM

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.
