javascript实现弹出层效果


Posted in Javascript onDecember 10, 2019

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>

}

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:

javascript实现弹出层效果

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

以上就是本文的全部内容,希望对大家的学习有所帮助,也希望大家多多支持三水点靠木。
