【JavaScript 封装库】BETA 3.0 测试版发布！
/*
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 3.0 版
迭代版本: BETA 2.0
插件总数: 8 个
库方法数: 20 个
功能总数: 48 个
新增总数: 7 个
删除总数: 0 个
追加功能:
1. 新增“插件库”支持, 可自由扩展网页特效插件
2. 新增“元素节点选择器”, 元素节点操纵简便性大大提升, 可读性加强
3. 新增“HTML DOM 加载”, 节省外部文件加载耗时
4. 库方法: 新增“CSS 处理”, 分离调用代码可读性加强
5. 库方法: 新增“class 处理”, 分离调用代码可读性加强
...
优化功能:
1. 优化节点定位并删除了 name 方式定位, 遵循 W3C 原则
2. 优化节点事件绑定, 集中至“nodeEvent”方法同一调用, 可读性、扩展性、维护性大大加强
3. 库方法: 优化“清除空白节点”, 采用倒序遍历, 删除更加彻底简便
4. 库方法: 优化“清除注释节点”, 采用倒序遍历, 删除更加彻底简便
....
删除功能:
