element plus 单选框取消选择

一定得使用 prevent 才行

<el-radio-group v-model="shadow"
    >{{ satellites }}
    <el-radio
        v-for="sa in satellites"
        @click.prevent="changeShadow(sa)"
        :value="sa"
        :label="sa"
        :key="sa"
        >{{ sa }}</el-radio
    >
</el-radio-group>

let shadow = ref()


const changeShadow = (val) => {
    val == shadow.value ? (shadow.value = "") : (shadow.value = val);
};
