网上我也见到一些分栏效果，也有一个jquery的插件jquery.splitter.js, 但是他们基本都没有解决一个问题：如果页面上有iframe, 当拖动分割线经过iframe的时候，鼠标不听使唤了,我曾经开过帖子讨论过这个问题。本例采用一个小技巧解决了这个问题，使拖动流畅。
复制代码 代码如下:
<html>
<head>
<title>Splitter demo</title>
<style>
#splitter_container{
width: 100%;
height: 100%;
border: solid #eee 1px;
margin: 0px;
padding: 0px;
overflow: hidden;
}
#splitter_left_panel{
width: 300px;
height: 100%;
float: left;
border: solid blue 0px;
}
#splitter_bar{
width: 8px;
height: 100%;
float: left;
background-color: #ccc;
cursor: col-resize;
}
#splitter_right_panel{
height: 100%;
padding-top: 10px;
}
</style>

在此处右键察看源代码并把其中的js保存为splitter.js<br>
splitter.js使用方法：<br>
页面上需要有一个div作为容器(id=splitter_container): 可拖动效果就在这个容器里面进行<br>
容器里面需要有3个div,分别代表左栏(id=splitter_left_panel)，分割线(id=splitter_bar), 右栏(id=splitter_right_panel)<br>
这4个div需要用css修饰一下<br>
<code>
#splitter_container{
width: 100%;
height: 100%;
border: solid #eee 1px;
margin: 0px;
padding: 0px;
overflow: hidden;
}<br>
#splitter_left_panel{
width: 300px;
height: 100%;
float: left;
border: solid blue 0px;
}<br>
#splitter_bar{
width: 8px;
height: 100%;
float: left;
background-color: #ccc;
cursor: col-resize;
}<br>
#splitter_right_panel{
height: 100%;
padding-top: 10px;
}
</code>
<br><br>
给body加上onload事件处理函数,以触发splitter: <br>
onload="Splitter.init({id: 'splitter_Container', isWidthLimit: true});" <br>
Splitter的init方法传入一个json对象作为配置参数,其中容器id是必需的.<br>
还可以配置更多的参数, 比如:<br>
isWidthLimit: 可选值true, false, 设置左面板是否限制宽度;<br>
lPanelMaxWidth: 左面板最大宽度,比如: 500px;<br>
lPanelMinWidth: 左面板最小宽度,比如: 100px;<br>
barActiveColor: 分割线拖动的时候的颜色: 比如'red', '#0080ff';<br>

《魔兽世界》大逃杀！60人新游玩模式《强袭风暴》3月21日上线
暴雪近日发布了《魔兽世界》10.2.6 更新内容，新游玩模式《强袭风暴》即将于3月21 日在亚服上线，届时玩家将前往阿拉希高地展开一场 60 人大逃杀对战。
艾泽拉斯的冒险者已经征服了艾泽拉斯的大地及遥远的彼岸。他们在对抗世界上最致命的敌人时展现出过人的手腕，并且成功阻止终结宇宙等级的威胁。当他们在为即将于《魔兽世界》资料片《地心之战》中来袭的萨拉塔斯势力做战斗准备时，他们还需要在熟悉的阿拉希高地面对一个全新的敌人──那就是彼此。在《巨龙崛起》10.2.6 更新的《强袭风暴》中，玩家将会进入一个全新的海盗主题大逃杀式限时活动，其中包含极高的风险和史诗级的奖励。
《强袭风暴》不是普通的战场，作为一个独立于主游戏之外的活动，玩家可以用大逃杀的风格来体验《魔兽世界》，不分职业、不分装备（除了你在赛局中捡到的），光是技巧和战略的强弱之分就能决定出谁才是能坚持到最后的赢家。本次活动将会开放单人和双人模式，玩家在加入海盗主题的预赛大厅区域前，可以从强袭风暴角色画面新增好友。游玩游戏将可以累计名望轨迹，《巨龙崛起》和《魔兽世界：巫妖王之怒 经典版》的玩家都可以获得奖励。
