jquery determines the browser method
jquery uses navigator.userAgent.indexOf to determine the browser type and does some processing. If you don’t want to use jquery, you can use it by slightly modifying the code
jquery Determine the source code of the browser (jquery1.31 as an example)
Js code:
var userAgent = navigator.userAgent.toLowerCase();
// Figure out what browser is being used
jQuery.browser = {
version: (userAgent.match( /. ( ?:rv|it|ra|ie)[/: ]([d.] )/ ) || [0,'0'])[1],
safari: /webkit/.test( userAgent ),
opera: /opera/.test( userAgent ),
msie: /msie/.test( userAgent ) && !/opera/.test( userAgent ),
mozilla: /mozilla/.test( userAgent ) && !/(compatible|webkit)/.test( userAgent )
};
version---browser version
msie----ie browser (Microsoft Internet Explorer)
mozilla-Firefox browser
opera--opera browser
Js code:
var userAgent = navigator.userAgent.toLowerCase();
browser={
version: (userAgent.match( /. (?:rv|it|ra|ie)[/: ]([d.] )/ ) || [0,'0'])[1],
safari: / webkit/.test( userAgent ),
opera: /opera/.test( userAgent ),
msie: /msie/.test( userAgent ) && !/opera/.test( userAgent ),
mozilla : /mozilla/.test( userAgent ) && !/(compatible|webkit)/.test( userAgent )
}
The call is the same as jquery, just remove the $ symbol

Use Jquery to determine the type of browser, if only to determine the type of browser It is not recommended to use this method. It is only recommended if you have already used jquery, because there is no need to load such a large class library for such a small function.
It is recommended that friends who are learning jquery study it and understand the ideas.
Mainly used method: $.browser.['browser keyword']
The code is as follows:

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.

The power of the JavaScript framework lies in simplifying development, improving user experience and application performance. When choosing a framework, consider: 1. Project size and complexity, 2. Team experience, 3. Ecosystem and community support.
