弹出层和弹窗相似但是并不相同;弹窗和弹出层都是由用户触发的显示提示信息的弹出面板;但是弹窗只是显示一些信息,没有太多的复杂的交互事件;而弹层类似一个整个页面,可以实现页面的所有功能;
现在前端弹层使用的很频繁,如支付宝支付弹层等…所以掌握弹层是一个很重要的技能。如果只是简单的隐藏和切换,当然就不必说,我要说的html+animate+es6实现弹层;
html弹层结构:
<main class="main"> <header class="head flex-center gray-theme">This is Header</header> <section class="body flex-center"> <ul class="btn-list flex-center btn-group"> <li class="btn-box"><span class="btn inline-flex-center" data-position="top">上弹层</span></li> <li class="btn-box"><span class="btn inline-flex-center" data-position="right">右弹层</span></li> <li class="btn-box"><span class="btn inline-flex-center" data-position="bottom">下弹层</span></li> <li class="btn-box"><span class="btn inline-flex-center" data-position="left">左弹层</span></li> </ul> </section> <footer class="foot flex-center gray-theme">This is Footer</footer> <!-- popup --> <section class="popup flex-center hide hidden"> <section class="popup-bg"></section> <section class="popup-wrapper"> <header class="title head flex-center"></header> <section class="container body flex-center"></section> <footer class="btn-wrapper foot flex-center"> <ul class="btn-list flex-center"> <li class="btn-box"><span class="btn cancel inline-flex-center">取消</span></li> <li class="btn-box"><span class="btn confirm inline-flex-center">确认</span></li> </ul> </footer> </section> </section> </main>

TB.addHandler:
/* * 给DOM元素添加事件 * @param void * @return callback function 回调函数 * */ function addHandler(elem, type, callback, useCapture) { var checkType = checkArgumentType(), _document = document, _callback = checkType.isFunction(callback)"on" + type, function(e){ _callback.apply(_self, [e]); }); } } else { addHandler = function(elem, type, callback, useCapture) { elem["on" + type] = function(e) { _callback.call(_self, e); }; } } addHandler(elem, type, callback, useCapture); }
首先说一下弹窗的DOM结构:
在外层一般是绝对定位,并使用flex布局使得内容居中;它的直接子元素一般有两个,黑色背景层和内容容器;如图所示:
样式的动画相信前端的同学一般都知道怎么做;但是有一点要注意,不要试图使用display来实现动画;
我使用的解决的办法是首先
动画的显示隐藏使用的z-index和opacity;但是这样存在开始时,弹窗会缓缓隐藏,那么我们可以用一个类表示display: none;点击显示弹层时,移除该类即可;
对于js没什么好说的,无非是操作类名;但是有一点要注意事件注册和this的指向;
注意我的addHandler函数,该函数只会判断一次浏览器的环境,不需要反复的判断浏览器的环境;
在btnGroupClickEvent函数中this是指向PopupComponent类,而不是事件的event;所以addHandler函数中首先保存this的指向,然后使用call或者apply改变this的指向

《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。
