Example
Switch different background colors:
$("p").toggle( function(){ $("body").css("background-color","green");}, function(){ $("body").css("background-color","red");}, function(){ $("body").css("background-color","yellow");} );
Definition and usage
toggle() method is used to bind two or more event handlers DeviceFunction, to respond to the click event of the selected element in turn.
This method can also be used to switch the hide() and show() methods of the selected element.
Bind two or more functions to the Toggle event
When the specified element is clicked, switch between two or more functions in turn.
If more than two functions are specified, the toggle() method will toggle all functions. For example, if there are three functions, the first click will call the first function, the second click will call the second function, and the third click will call the third function. The fourth click calls the first function again, and so on.
Syntax
$(selector).toggle(function1(),function2(),functionN(),...)
Try it yourself
Parameters | Description |
---|---|
function1() | Required. Specifies a function to run when the element is clicked every even number of times. |
function2() | Required. Specifies a function to be run every odd number of times the element is clicked. |
functionN(),... | Optional. Specify other functions that need to be switched. |
Switch Hide() and Show()
Check whether each element is visible.
Run show() if the element is hidden. If the element is visible, the element hide(). This creates a switching effect.
Syntax
$(selector).toggle(speed,callback)
Try it yourself
Parameters | Description |
---|---|
speed |
Optional. Specifies the speed of hide/show effects. The default is "0". Possible values:
|
Optional. Function executed when the toggle() method completes. To learn more about callback, please visit our Callback function tutorial. |
$(selector).toggle(switch)
Try it yourself
Description | |
---|---|
switch | Required. A Boolean value that specifies whether toggle() should only show or hide all selected elements.

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.
