 14     export default {
 15         name: 'switchComponent',
 16         props: {
 17           value: {
 18             type: Boolean,

 37                 }
 38             }

 40         watch: {
 41           value (val) {
 42             this.isChecked = val
 43           },
 44           isChecked(val) {
 45             this.$emit('change', val);
 46           }
 47         },

 52         }
 53     }    
 54 </script>
 55 <style>
 56     .weui-switch {
 57         display: block;
 58         position: relative;
 59         width: 52px;
 60         height: 24px;
 61         border: 1px solid #DFDFDF;
 62         outline: 0;
 63         border-radius: 16px;
 64         box-sizing: border-box;
 65         background-color: #DFDFDF;
 66         transition: background-color 0.1s, border 0.1s;
 67         cursor: pointer;
 68       }
 69       .weui-switch:before {
 70         content: " ";
 71         position: absolute;
 72         top: 0;
 73         left: 0;
 74         width: 50px;
 75         height: 22px;
 76         border-radius: 15px;
 77         background-color: #FDFDFD;
 78         transition: transform 0.35s cubic-bezier(0.45, 1, 0.4, 1);
 79       }
 80       .weui-switch:after {
 81         content: " ";
 82         position: absolute;
 83         top: 0;
 84         left: 0;
 85         width: 22px;
 86         height: 22px;
 87         border-radius: 15px;
 88         background-color: #FFFFFF;
 89         box-shadow: 0 1px 3px rgba(0, 0, 0, 0.4);
 90         transition: transform 0.35s cubic-bezier(0.4, 0.4, 0.25, 1.35);
 91       }
 92       .weui-switch-on {
 93         border-color: #6F6F6F;
 94         background-color: #1AAD19;
 95       }
 96       .weui-switch-on:before {
 97         border-color: #1AAD19;
 98         background-color: #409eff;
 99       }
100       .weui-switch-on:after {
101         transform: translateX(28px);
102       }
103 </style>

在父组件中引入

<template>
  <div>
    <switch v-model="value" text="on|off"></switch>
  </div>
  
</template>

<script>
import switch from './components/Switch'
export default {
  name: "App",
  components: {
    switch
  },
  data() {
    return {
        value:''
  },
  methods:{

  }
};
</script>

<style lang="less">

</style>

效果如下
