1.利用css实现开关按钮

效果图如下所示：

2.HTML代码

 

3.css代码

.testswitch {

    position: relative;

    float: left;

    width: 45px;

    margin: 0;

    font-size: 0.6em;

}

.testswitch-checkbox {

    display: none;

}

.testswitch-label {

    display: block;

    overflow: hidden;

    cursor: pointer;

    border-radius: 20px;

}

.testswitch-inner {

    display: block;

    width: 200%;

    margin-left: -100%;

    transition: margin 0.3s ease-in 0s;

    text-align: left;

}

.testswitch-inner::before,

.testswitch-inner::after {

    display: block;

    float: right;

    width: 50%;

    height: 20px;

    padding: 0;

    line-height: 1.8em;

    font-size: 8px;

    color: white;

    font-family: Trebuchet, Arial, sans-serif;

    font-weight: bold;

    box-sizing: border-box;

}

.testswitch-inner::after {

    content: attr(data-on);

    padding-left: 10px;

    background-color: #FFAB47;

    color: #FFFFFF;

}

.testswitch-inner::before {

    content: attr(data-off);

    padding-right: 10px;

    background-color: #3F9FE8;

    color: white;

    text-align: right;

}

.testswitch-switch {

    position: absolute;

    display: block;

    width: 12px;

    height: 12px;

    margin: 4px;

    background: #FFFFFF;

    bottom: 5px;

    border-radius: 20px;

    transition: all 0.3s ease-in 0s;

    text-align: right;

}

.testswitch-checkbox:checked+.testswitch-label .testswitch-inner {

    margin-left: 0;

}

.testswitch-checkbox:checked+.testswitch-label .testswitch-switch {

    right: 0px;

}

4.根据off和on的值不同做出不同的事件处理
