【JavaScript 封装库】BETA 2.0 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 2.0 版
迭代版本: BETA 1.0
功能总数: 50 个
新增总数: 6 个
删除总数: 0 个
追加功能:
1. 库方法: 设置与获取滚动条
2. 库方法: 定位器筛选
3. 库方法: 检测元素从属关系(直接从属)
4. 库方法: 获取网页可视区尺寸
5. 库方法: 禁止页面滚动(修正浏览器BUG)
...
优化功能:
1. 取消了“隶属方法”, 增加了“库方法”并与“特效”和“事件”组成集合, 封装库结构更加清晰
2. 元素节点获取更加智能, 支持 class / name / tagName / id 在内的局部搜索
3. 添加与删除元素节点更加方便容易, 支持 class / name / tagName / id 直接定位
...
删除功能:
无
