先看效果：

element-ui中的switch开关无loading属性（在element-plus时加入了），而且点击时开关状态就会切换，这使得在需要调用接口后再改变开关状态变得比较麻烦。

思路：switch开关外包一层div，给div添加click事件，emit给父组件，在父组件里进行开关状态的切换。

开关组件源码：

<template><div class="custom-switch" @click="switchClick"><div style="width: fit-content;height: fit-content;" v-loading="loading"><el-switch style="position: relative;" v-bind="$attrs"></el-switch></div></div>
</template><script>
/*** el-switch开关组件二次封装* * description:* 移除了el-switch的change事件* 添加了loading效果* 开关的value值交给父组件处理*/
export default {name: 'CustomSwitch',props: {loading: {default: false,type: Boolean}},data() {return {}},created() {},mounted() {},methods: {switchClick() {// 如果禁用和loading状态，不emit给父组件if (this.$attrs.disabled || this.loading) {return}this.$emit('switch-click', this.$attrs.value)}}
}
</script>
<style lang="scss" scoped>
.custom-switch {width: 100%;height: 100%;display: flex;align-items: center;justify-content: center;::v-deep .el-loading-mask {width: 100%;height: 100%;border-radius: 10px;top: 2px;.el-loading-spinner {position: relative;width: 100%;height: 100%;top: unset;margin-top: unset;display: flex;align-items: center;justify-content: center;svg {width: 20px;height: 20px;}}}
}
</style>

父组件：

<template><custom-switchv-model="switchValue":loading="switchLoading":active-value="1":inactive-value="0":disabled="switchDisabled"@switch-click="switchClick"/>
</template>

<script>
import CustomSwitch from './custom-switch.vue'export default {components: { CustomSwitch },data() {return {switchValue: 1,switchLoading: false,switchDisabled: false}},methods: {switchClick() {this.switchLoading = true// 这里就可以调用接口，接口成功后修改值和loading状态setTimeout(() => {this.switchValue = !this.switchValue ? 1 : 0this.switchLoading = false}, 2000)}}
}
</script>
