Yesterday, a netizen suddenly asked me whether the animate() method can operate all css attributes? Yes, I told him it could. However, there is something to note here that everyone needs to understand: when using animate(), all attribute names must be written in Camel notation. For example, paddingLeft must be used instead of padding-left, and marginRight must be used instead of margin-right. etc.
Not all attributes in css can be dynamically changed using Jquery animation (animate function). Here is a summary of some attributes that JQ can operate on elements:
* backgroundPosition * borderWidth * borderBottomWidth * borderLeftWidth * borderRightWidth * borderTopWidth * borderSpacing * margin * marginBottom * marginLeft * marginRight * marginTop * outlineWidth * padding * paddingBottom * paddingLeft * paddingRight * paddingTop * height * width * maxHeight * maxWidth * minHeight * maxWidth * font * fontSize(在animate函数的css参数指定并不同于标准css属性,例如这个css标准是:font-size。 同理上面很多也是这样的情况) * bottom * left * right * top * letterSpacing * wordSpacing * lineHeight * textIndent * opacity
Remember these can be animated~~
jquery’s animate() method can also set non-css attributes
As in the title, for example :
$('body').animate({scrollTop:0}, 1500); $("body").animate({scrollTop:"-="+50},350);
A few other small examples:
Disabled elements:
$('button').attr('disabled', 'disabled'); $('button').removeAttr('disabled');
Traverse the element collection:
$("input:text").each(function(index){ alert(index);//循环的下标值,从0开始 alert(this.value);//自带属性可以用this(Dom)直接取值 alert($(this).attr("type"));//自定义属性需要用attr()取值 });
The above is a summary of operating css style attributes based on jquery animate_ The content of jquery, please pay attention to the PHP Chinese website (www.php.cn) for more related content!

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.
