<div class="switch-list"> <span class="fui-fr">红色switch组件</span> <input class="fui-switch" style="color:rgb(255, 0, 0);" type="checkbox" checked> </div> <div class="switch-list"> <span class="fui-fr">绿色switch组件</span> <input class="fui-switch" style="color:rgb(76, 216, 100);" type="checkbox" checked> </div> <div class="switch-list"> <span class="fui-fr">绿色禁用switch组件</span> <input class="fui-switch" style="color:rgb(76, 216, 100);" type="checkbox" checked disabled> </div> <div class="switch-list"> <span class="fui-fr">蓝色switch组件---开</span> <input class="fui-switch" style="color:blue" type="checkbox" checked> </div> <div class="switch-list"> <span class="fui-fr">蓝色switch组件---关</span> <input class="fui-switch" style="color:blue" type="checkbox"> </div>
CSS
.switch-list{ padding: .5rem; } .fui-switch{ position: relative; width: .87rem; height: .5rem; z-index: 10; display: inline-block; outline: medium; border: 1px solid #dfdfdf; border-radius: .25rem; background-color: #dfdfdf; -webkit-appearance: none; -moz-appearance: none; vertical-align: middle; } .fui-switch:checked{ border-color: currentColor; background-color: currentColor; } .fui-switch::after,.fui-switch::before{ content: ""; position: absolute; height: .44rem; top: 0; left: 0; border-radius: .25rem; -webkit-transition: -webkit-transform .3s; transition: -webkit-transform .3s; transition: transform .3s; transition: transform .3s,-webkit-transform .3s; } .fui-switch:before { width: .84rem; background-color: #fdfdfd; } .fui-switch:checked:before { -webkit-transform: scale(0); transform: scale(0); } .fui-switch:after { width: .44rem; background-color: #fff; box-shadow: 0 1px 3px rgba(0,0,0,.4); } .fui-switch:checked:after { -webkit-transform: translateX(.4rem); transform: translateX(.4rem); } .fui-switch[disabled] { opacity: .5; } .fui-fr{font-size: .3rem;vertical-align: middle;}
实现rem的JS
(function(win,factory){ factory(win); window.addEventListener('resize',function(){factory(win)},false); }(window,function(win){ var width = document.documentElement.clientWidth; width = width > 750 ? 750 : width; document.documentElement.style.fontSize = width / 7.5 + 'px'; }));
注意
此处 1rem 在 750 的 psd 设计图代表 100px ;
switch 的切换动画是通过 CSS3 的 transition 属性实现;
主要是控制 switch 的 after 的移动,以及 before 的放大缩小动画。
