一个简洁的 JavaScript 库

Jun 07, 2016 am 11:44 AM

easy.js 是一个简洁易用的 JavaScript 库,包含了核心库和组件库。核心库有符合 W3C 标准的 CSS3 选择器,常用的 DOM 操作方法,增强的动画模块,支持 promise 模式的 ajax 模块以及优雅便捷的事件处理模块。easy.js 还集成了模块加载器,遵循 AMD 的模块化规范。组件库是基于核心库开发的,目前为止有一些最常见的组件诸如 Drag(对话框)、Switchable(轮播)、Lazyload(延迟加载)、Dialog(对话框)等等,后续还会继续开发更多的常用组件。

后续在放出一套配套的UI库,方便与程序开发实现无需一行CSS代码实现模块化美化快速开发!

简单性
easy.js的组件在 UI(界面) 层面尽量保持简单,开发者可以很方便的通过修改 CSS 样式就可以轻松定制自己想要的样式。
使用一个组件通常情况下只需要寥寥几行 JS 代码。


一致性
组件在接口设计、命名规则上都尽可能的保持一致。通常,你只要使用过任意一个组件,那么其他组件也很容易上手。

模块化
每个组件都是一个独立的符合 AMD 规范的模块,都依赖 easy.js 的核心库,在使用时都可以通过 E.use 来进行加载。

命名空间
所有组件的命名空间都是 E.ui,在组件加载完后都可以通过 E.ui.xxxx 来访问。

实例化
在使用组件时都需要通过 new 关键字来实例化,组件类的首字母都是 大写。
实例化时,第一个参数 都是必需的,该参数通常都是设置需要实例化某个/组 DOM 元素。该参数可以是选择器字符串、DOM 元素以及 easyJS Object 的对象。
实例化时,第二个参数 都是可选的,该参数是一个多选可配置形式的 Object 对象。

事件处理
组件在实例化后都可以通过 on 方法来为组件绑定事件,同样,也可以通过 un 方法来卸载事件。各组件支持的事件类型可以在详细的说明文档中看到。在多选形式的配置参数中,除了可能存在 init 回调函数,不会有任何其他的回调。

销毁实例
组件实例可以通过 destroy 方法进行销毁。

如何使用:
定义一个模块,将以下代码保存成 hello.js 文件:define(function(){<br>     // 该模块返回一个由easyJS封装的div元素   <br>     return E( '<div>hello easy.js !</div>' );<br> });使用该模块:var btn = E( '#demoHelloBtn' );<br> // 为按钮绑定一个一次性的事件<br> btn.one( 'click', function( e ){<br>     // 加载hello模块<br>     E.use( 'hello', function( helloDiv ){<br>         var win = E( window );<br>         // 将模块中的div插入到body中<br>         E( 'body' ).append( helloDiv );       <br>         // 设置div出现在页面的左下角<br>         helloDiv.css( 'top', win.scrollTop() + win.height() - 150 + 'px' )<br>             // 动画效果展示<br>             .anim({<br>                 to : { left : '0px' },<br>                 easing : 'doubleSqrt'<br>             });           <br>     });       <br>     e.preventDefault();        <br> });运行

开源
easy.js 遵循 MIT 协议,个人和企业都可以免费使用,easy.js on github。

Guidance and Examples: Learn to implement the selection sort algorithm in Java Guidance and Examples: Learn to implement the selection sort algorithm in Java Feb 18, 2024 am 10:52 AM

Java Selection Sorting Method Code Writing Guide and Examples Selection sorting is a simple and intuitive sorting algorithm. The idea is to select the smallest (or largest) element from the unsorted elements each time and exchange it until all elements are sorted. This article will provide a code writing guide for selection sorting, and attach specific Java sample code. Algorithm Principle The basic principle of selection sort is to divide the array to be sorted into two parts, sorted and unsorted. Each time, the smallest (or largest) element is selected from the unsorted part and placed at the end of the sorted part. Repeat the above
