返回值:jQueryanimate(params, [duration], [easing], [callback])
概述
用于创建自定义动画的函数。
这个函数的关键在于指定动画形式及结果样式属性对象。这个对象中每个属性都表示一个可以变化的样式属性(如“height”、“top”或“opacity”)。注意:所有指定的属性必须用骆驼形式,比如用marginLeft代替margin-left.
而每个属性的值表示这个样式属性到多少时动画结束。如果是一个数值,样式属性就会从当前的值渐变到指定的值。如果使用的是“hide”、“show”或“toggle”这样的字符串值,则会为该属性调用默认的动画形式。
在 jQuery 1.2 中,你可以使用 em 和 % 单位。另外,在 jQuery 1.2 中,你可以通过在属性值前面指定 " =" 或 "-=" 来让元素做相对运动。
jQuery 1.3中,如果duration设为0则直接完成动画。而在以前版本中则会执行默认动画。
参数
paramsOptions一组包含作为动画属性和终值的样式属性和及其值的集合
duration (可选)String,Number三种预定速度之一的字符串("slow", "normal", or "fast")或表示动画时长的毫秒数值(如:1000)
easing (可选)String要使用的擦除效果的名称(需要插件支持).默认jQuery提供"linear" 和 "swing".
callback (可选)Function在动画完成时执行的函数
示例
描述:
点击按钮后div元素的几个不同属性一同变化
HTML 代码:
复制代码 代码如下:

// 在一个动画中同时应用三种类型的效果
$("#go").click(function(){
$("#block").animate({
width: "90%",
height: "100%",
fontSize: "10em",
borderWidth: 10
}, 1000 );
});

描述:
让指定元素左右移动
HTML 代码:
复制代码 代码如下:

$("#right").click(function(){
$(".block").animate({left: ' 50px'}, "slow");
});
$("#left").click(function(){
$(".block").animate({left: '-50px'}, "slow");
});

描述:
在600毫秒内切换段落的高度和透明度
jQuery 代码:
复制代码 代码如下:

$("p").animate({
height: 'toggle', opacity: 'toggle'
}, "slow");

描述:
用500毫秒将段落移到left为50的地方并且完全清晰显示出来(透明度为1)
jQuery 代码:
复制代码 代码如下:

$("p").animate({
left: 50, opacity: 'show'
}, 500);

描述:
一个使用“easein”函数提供不同动画样式的例子。只有使用了插件来提供这个“easein”函数,这个参数才起作用。
jQuery 代码:
复制代码 代码如下:

$("p").animate({
opacity: 'show'
}, "slow", "easein");

Python vs. JavaScript: A Comparative Analysis for DevelopersPython vs. JavaScript: A Comparative Analysis for DevelopersMay 09, 2025 am 12:22 AM

The main difference between Python and JavaScript is the type system and application scenarios. 1. Python uses dynamic types, suitable for scientific computing and data analysis. 2. JavaScript adopts weak types and is widely used in front-end and full-stack development. The two have their own advantages in asynchronous programming and performance optimization, and should be decided according to project requirements when choosing.

Python vs. JavaScript: Choosing the Right Tool for the JobPython vs. JavaScript: Choosing the Right Tool for the JobMay 08, 2025 am 12:10 AM

Whether to choose Python or JavaScript depends on the project type: 1) Choose Python for data science and automation tasks; 2) Choose JavaScript for front-end and full-stack development. Python is favored for its powerful library in data processing and automation, while JavaScript is indispensable for its advantages in web interaction and full-stack development.

Python and JavaScript: Understanding the Strengths of EachPython and JavaScript: Understanding the Strengths of EachMay 06, 2025 am 12:15 AM

Python and JavaScript each have their own advantages, and the choice depends on project needs and personal preferences. 1. Python is easy to learn, with concise syntax, suitable for data science and back-end development, but has a slow execution speed. 2. JavaScript is everywhere in front-end development and has strong asynchronous programming capabilities. Node.js makes it suitable for full-stack development, but the syntax may be complex and error-prone.

The Relationship Between JavaScript, C  , and BrowsersThe Relationship Between JavaScript, C , and BrowsersMay 01, 2025 am 12:06 AM

Introduction I know you may find it strange, what exactly does JavaScript, C and browser have to do? They seem to be unrelated, but in fact, they play a very important role in modern web development. Today we will discuss the close connection between these three. Through this article, you will learn how JavaScript runs in the browser, the role of C in the browser engine, and how they work together to drive rendering and interaction of web pages. We all know the relationship between JavaScript and browser. JavaScript is the core language of front-end development. It runs directly in the browser, making web pages vivid and interesting.

mPDF

mPDF

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
