JavaScript 封装库

javascript web前端封装库框架技术

/*
	源码作者: 石不易(Louis Shi)
	联系方式: http://www.shibuyi.net
	===================================================================================
	程序名称: JavaScript 封装库 BETA 4.0 版
	迭代版本: BETA 3.0
	插件总数: 12 个
	库方法数: 26 个
	功能总数: 67 个
	新增总数: 22 个
	删除总数: 3 个
	追加功能: 
		1. 进一步完善“获取元素节点”的功能, 包括: 前后位兄弟节点、子节点、父节点
		2. 新增“获取元素节点尺寸”, 可直接输出元素的宽高和坐标
		3. 库方法: 新增对 CSS 样式原生风格的解析, 支持 JavaScript 与 CSS 的两种; 例如: fontSize 也可写作 font-size
		4. 插件: 新增“元素动画”特效, 支持常规的宽高运动、坐标运动和透明度渐变; 另外也可自定义, 但必须要有对应像素单位的样式, 否则无效
		5. 插件: 新增“事件切换器”特效, 支持任意方法数, 点击元素后迭代切换事件
		...
	优化功能: 
		1. 优化了 CSS 解析功能, 支持原生和 JavaScript 两种写法, 可任意混合搭配
		2. 优化了“移除样式规则”, 从原先的索引下标移除转变为直接输入对应选择器名称即可删除, 但 W3C 与 IE 6/7/8 在选择器多重叠加上的解释并不一致, 需谨慎使用
		2. 优化了“自动加载插件”, 载入插件时直接将插件方法名变量传入即可, 但不支持匿名函数赋值给变量后在传入的写法
		4. 插件: 优化了“元素居中”特效, 现已支持 3 种居中方式: 水平居中、垂直居中、水平+垂直居中
		...
	删除功能: 
		1. 库方法: 删除了“初始化滚动条”方法, 今后直接通过“滚动条”方法设置即可
		2. 库方法: 删除了“CSS 处理”方法, 与“添加元素节点属性”结合, 无需再分离调用
		3. 库方法: 删除了“class 处理”方法, 与“添加元素节点属性”结合, 无需再分离调用
