前端实现滑动开关

  日常开发中实现开关,或者更准确说实现单击按钮效果的方法很多,问题是怎么做才能让其更美观的展示在浏览器上。

  效果图如下:

        

  之前在网上看过不少实现的方法,其中就有一个是使用纯css3写出来的,以下是纯css代码实现的网站地址:https://proto.io/freebies/onoff/

  以下是该网站上展示的的源码:

 6         .onoffswitch {

10             -moz-user-select:none; 
11             -ms-user-select: none;

42         .onoffswitch-inner:before {
43                 content: "on";
44                 padding-left: 10px;

56         .onoffswitch-switch {
57             display: block;

70         }
71         .onoffswitch-checkbox:checked + .onoffswitch-label .onoffswitch-switch {
72             right: 0px; 
73             background-color: #27A1CA; 
74         }

77 <body>
78 <div class="onoffswitch">
79     
80     <input type="checkbox" name="onoffswitch" class="onoffswitch-checkbox" id="myonoffswitch">
81     <label class="onoffswitch-label" for="myonoffswitch">

83         <span class="onoffswitch-switch">span>
84     label>

86 body>
87 html>

  在这里,不得不说很佩服写出以上源码的作者,确实很牛,但是以上代码太过繁琐复杂,而如果使用js实现反而更加通俗易懂

  以下是我自己写的实现滑动开关的HTML+CSS+Jquery代码,
