##jQuery.hide () Detailed explanation of function

hide()

Function is used toHide all matching elements. Additionally, you can specify transition animation effects that are hidden by the element.

If the element itself is invisible, no changes are made to it. If the element is visible, hide it.

Relative to this function is the show() function, which is used to

display all matching elements

. This function belongs to the jQuery object (instance).

Syntax

jQuery 1.0 Added this function. hide()

The function mainly has the following two forms of usage:

Usage 1: jQuery

1.4.3 Added support parameter

easing.

jQueryObject.hide( [ duration ] [, easing ] [, complete ] )

Usage Two:

jQueryObject.hide( options )

Usage Two is a variation of Usage One. Specify the required option parameters in object form (you can specify more option parameters than Usage 1).

Parameters

##Parameters

Description##Optional/String/Number type specifies transition How long to run the animation in milliseconds. The default value is 400. This parameter can also be a ##Optional/String type specifies which animation effect to use, default It can be set to "swing", or it can also be set to "linear" or Optional/Function type element needs to be executed after hiding . this within the function points to the current DOM element. ##Object class The option parameter object specified by type .

如果没有为hide()指定任何参数，则将以最快方式直接隐藏元素，不使用动画效果。

参数options对象可以识别如下的属性(以下属性均是可选的)：

	duration
	string "fast"(=200) or "slow"(=600). easing
The function name of other customized animation styles.	swing: swing effect (swing), slow on both sides and fast in the middle. linear: linear complete
	options

属性	属性描述
duration	参见参数`duration`。
easing	参见参数`easing`。
complete	参见参数`complete`。
queue	Boolean类型指示是否将动画放入效果队列中，默认为`true`。从1.7版本开始，该参数可以为字符串，用于放入指定名称的效果队列。如果你指定的队列不会自动开始，你需要手动调用dequeue("queueName")来启动队列。

此外，jQuery 1.4 和 1.8 还为参数options新增了许多新的选项支持，但这些参数并不常用，此处不再赘述，详见jQuery官方文档。

返回值

hide()函数的返回值为jQuery类型，返回当前jQuery对象本身。

From Websites to Apps: The Diverse Applications of JavaScriptApr 22, 2025 am 12:02 AM

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 vs. JavaScript: Use Cases and Applications ComparedApr 21, 2025 am 12:01 AM

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.

The Role of C/C in JavaScript Interpreters and CompilersApr 20, 2025 am 12:01 AM

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 in Action: Real-World Examples and ProjectsApr 19, 2025 am 12:13 AM

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.

JavaScript and the Web: Core Functionality and Use CasesApr 18, 2025 am 12:19 AM

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 the JavaScript Engine: Implementation DetailsApr 17, 2025 am 12:05 AM

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 vs. JavaScript: The Learning Curve and Ease of UseApr 16, 2025 am 12:12 AM

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 vs. JavaScript: Community, Libraries, and ResourcesApr 15, 2025 am 12:16 AM

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.
