JQuery plug-in is its extension method, so there are countless plug-ins since the development of JQuery, but there are several commonly used ones that you can learn about.
jQuery form validation plug-in: Validation
The most common occasion where JavScript is used is form validation, and jQuery is used as An excellent JavaScript library also provides an excellent form validation plug-in - Validation. Validation is one of the oldest jQuery plug-ins. It has been verified by different projects around the world and has been praised by many web developers. As a standard verification method library,
Validation has the following advantages:
Built-in validation rules: It has 19 types of built-in validation rules such as required, numbers, E-Mail, URL and credit card number
Customized verification rules: You can easily customize verification rules
Simple and powerful verification information prompts: The verification information prompts are defaulted and provide the function of customizing the default prompt information
Real-time verification: Verification can be triggered through keyup or blur events, not just when the form is submitted.
jQuery form plug-in: Form
jQuery Form plug-in is an excellent Ajax form plug-in that can easily and non-invasively upgrade HTML forms to support Ajax. jQuery has two core methods - ajaxForm() and ajaxSubmit(), which combine functionality from controlling form elements to deciding how to manage the submission process. In addition, iain, the
plug-in also includes other methods:
formToArray(), formSerialize(), fieldSerialize(), fieldValue(), clearForm() and resetForm(), etc.
jQuery UI plug-in
jQuery UI is derived from a jQuery plug-in - Interface. The earliest version of the Interface plug-in was 1.2, which only supported the jQuery 1.1.2 version. Later, some people reconstructed most of the Interface representatives based on the jQuery 1.2 API and unified the API. Due to major improvements, the version number is not 1.3 but jumps directly to 1.5 and is renamed jQuery UI.
jQuery UI is mainly divided into 3 parts, interaction, widgets and effects library
Interaction. Here are some content related to mouse interaction. Including dragging, placing, zooming, selecting and sorting etc. Some of the widgets are made based on these interactive components. This library requires a jQuery UI core library - ui.core.js supports
widgets. Here are mainly some interface extensions. It includes accordion navigation, autocomplete, color picker, dialog box, slider, label, calendar, magnifying glass, progress bar and spinner controller. This library requires a jQuery UI core library - ui.core.js supports the
effects library. This library is used to provide rich animation effects, so that animation is no longer limited to the animate() method. The effects library has its own set of core, effects.core.js, which does not require jQuery's core library ui.core.js to support
Dynamic binding event plug-in: livequery
Query's event binding function enables the complete separation of jQuery code and HTML code, making the hierarchical relationship of the code clearer and easier to maintain. However, for HTML elements that are dynamically loaded into the page, events need to be re-binded to these elements every time, which is very inconvenient.
A new plug-in was born from this, namely livequery, which can be used to register the time for the corresponding DOM element or trigger the callback function. Not only will the element matched by the current selector be bound to the event, but also elements added later via JavaScript will be bound to the event. When the element no longer matches the selector, livequery will automatically cancel the event registration, so that developers no longer need to pay attention to the source of the HTML element, only how to write its bound events.
Select a DOM element through the jQuery selector, and the livequery plug-in will persist it in the entire DOM range in real time. This means that whether the element previously existed or was dynamically loaded later, the event will be bound, just like CSS styling the element. At the same time, this plug-in achieves these functions without taking up almost any resources.
Plug-in to manage cookies: Cookie
Cookies are small text files placed on the client by website designers. Cookies can provide users with a lot of conveniences, such as shopping websites storing product lists that users have browsed, or portal websites remembering what types of news users like to browse. When the user is running, the user's login status can also be stored, so that the user does not have to enter this information every time when visiting the website. jQuery provides a very simple plug-in to manage cookies on the website. The name of the plug-in is also Cookie.Modal window plug-in: SimpleModal

JavaScript is widely used in websites, mobile applications, desktop applications and server-side programming. 1) In website development, JavaScript operates DOM together with HTML and CSS to achieve dynamic effects and supports frameworks such as jQuery and React. 2) Through ReactNative and Ionic, JavaScript is used to develop cross-platform mobile applications. 3) The Electron framework enables JavaScript to build desktop applications. 4) Node.js allows JavaScript to run on the server side and supports high concurrent requests.

Python is more suitable for data science and automation, while JavaScript is more suitable for front-end and full-stack development. 1. Python performs well in data science and machine learning, using libraries such as NumPy and Pandas for data processing and modeling. 2. Python is concise and efficient in automation and scripting. 3. JavaScript is indispensable in front-end development and is used to build dynamic web pages and single-page applications. 4. JavaScript plays a role in back-end development through Node.js and supports full-stack development.

C and C play a vital role in the JavaScript engine, mainly used to implement interpreters and JIT compilers. 1) C is used to parse JavaScript source code and generate an abstract syntax tree. 2) C is responsible for generating and executing bytecode. 3) C implements the JIT compiler, optimizes and compiles hot-spot code at runtime, and significantly improves the execution efficiency of JavaScript.

JavaScript's application in the real world includes front-end and back-end development. 1) Display front-end applications by building a TODO list application, involving DOM operations and event processing. 2) Build RESTfulAPI through Node.js and Express to demonstrate back-end applications.

The main uses of JavaScript in web development include client interaction, form verification and asynchronous communication. 1) Dynamic content update and user interaction through DOM operations; 2) Client verification is carried out before the user submits data to improve the user experience; 3) Refreshless communication with the server is achieved through AJAX technology.

Understanding how JavaScript engine works internally is important to developers because it helps write more efficient code and understand performance bottlenecks and optimization strategies. 1) The engine's workflow includes three stages: parsing, compiling and execution; 2) During the execution process, the engine will perform dynamic optimization, such as inline cache and hidden classes; 3) Best practices include avoiding global variables, optimizing loops, using const and lets, and avoiding excessive use of closures.

Python is more suitable for beginners, with a smooth learning curve and concise syntax; JavaScript is suitable for front-end development, with a steep learning curve and flexible syntax. 1. Python syntax is intuitive and suitable for data science and back-end development. 2. JavaScript is flexible and widely used in front-end and server-side programming.

Python and JavaScript have their own advantages and disadvantages in terms of community, libraries and resources. 1) The Python community is friendly and suitable for beginners, but the front-end development resources are not as rich as JavaScript. 2) Python is powerful in data science and machine learning libraries, while JavaScript is better in front-end development libraries and frameworks. 3) Both have rich learning resources, but Python is suitable for starting with official documents, while JavaScript is better with MDNWebDocs. The choice should be based on project needs and personal interests.
