jquery隐藏侧边栏和折叠侧边栏方法_class="sidebar-collapse

class="sidebar-collapse

两种效果如下所示:

隐藏侧边栏:

 

折叠侧边栏:

 

下面,分享隐藏侧边栏实现方法:

实现思路:给body切换class,通过class控制侧边栏和主体部分left 来实现效果

html部分:

< div  class="sidebar">侧边栏</ div >
< div  class="main">主体部分</ div >

 

css部分:

.sidebar{ background #333645 ; width 200px position absolute left 0 top 0 height 100% overflow auto ; transition:  all  0.2 s ease  0 s;}
.main{ overflow hidden position absolute left 200px right 0 height 100% ; transition:  all  0.2 s ease  0 s;}
.big-page .sidebar{ left -200px ;}
.big-page .main{ left 0 ;}

// 切换侧边栏
$( function (){
     // 切换侧边栏
     $( ".navbar-left li" ).click(toggleSidebar);
});
 
 
//切换侧边栏显示隐藏
function  toggleSidebar(){
     $( "body" ).toggleClass( "big-page" );
     return  false ;
}

 

折叠侧边栏实现方法:

实现思路:和隐藏侧边栏实现基本上相同,折叠后(只显示图标的时候)使用css控制栏目显示和隐藏。

在线效果:折叠侧边栏效果, 我真是操碎了心(捂脸)
