For example, your current URL is:
http://www.jb51.net/index.php?test=1&kk=2
If you want to get the test, you can introduce the plug-in and use
Get it as follows:
var test = $.query.get('test');
If the parameters have multiple identical names, you can do this:
var arr = $.query. get('testy');
Output: [Value 1, Value 2, Value 3...]
If you want to get one of multiple identical names, you can do this:
var arrayElement = $.query.get('testy[1]');
This plug-in can not only get parameters, but also set parameters.
Set a parameter:
var newUrl = $.query.set("section", 5).toString();
Output: "?section=5"
Set two parameters:
var newUrl = $.query.set("section", 5).set("action", "do").toString();
Output: "?action=do§ ion=5"
Remove a parameter:
var oldQueryAgain = $.query.REMOVE("type");
Empty all parameters:
var emptyQuery = $.query.empty();
Copy all parameters:
var stillTheSame = $.query.copy();

The latest trends in JavaScript include the rise of TypeScript, the popularity of modern frameworks and libraries, and the application of WebAssembly. Future prospects cover more powerful type systems, the development of server-side JavaScript, the expansion of artificial intelligence and machine learning, and the potential of IoT and edge computing.

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.

Python is more suitable for data science and machine learning, while JavaScript is more suitable for front-end and full-stack development. 1. Python is known for its concise syntax and rich library ecosystem, and is suitable for data analysis and web development. 2. JavaScript is the core of front-end development. Node.js supports server-side programming and is suitable for full-stack development.

JavaScript does not require installation because it is already built into modern browsers. You just need a text editor and a browser to get started. 1) In the browser environment, run it by embedding the HTML file through tags. 2) In the Node.js environment, after downloading and installing Node.js, run the JavaScript file through the command line.
