导读：折叠菜单，TAB切换，核心图，滑动门JS代码封装，一个页面将这些常用的网页元素齐集在了一路，想用谁人的时辰，配置一下就行了，好比应用于折叠层，想要睁开当前的同时，其余状态稳固，修改other值为show。想要初始化时确定哪一项睁开，修改initCon值为有用

　　折叠菜单，TAB切换，核心图，滑动门JS代码封装，一个页面将这些常用的网页元素齐集在了一路，想用谁人的时辰，配置一下就行了，好比应用于折叠层，想要睁开当前的同时，其余状态稳固，修改"other"值为"show"。想要初始化时确定哪一项睁开，修改"initCon"值为有用数字;

　　应用于选项卡：本例行使callback函数来改变tab的样式。"event"配置鼠标变乱范例，"event":"mouseover"改为鼠标划过。

　　演示：
