1.写遮罩

2.定义data

3.写事件

4.效果图

补充知识：vue使用vant编辑用户性别

我就废话不多说了，大家还是直接看代码吧~

<van-cell title="性别" is-link :value="user.gender===1?'男':'女'" @click="isEditGenderShow=true"></van-cell>
<!-- 编辑用户性别 -->
  <van-action-sheet
   v-model="isEditGenderShow"
   :actions="actions"
   cancel-text="取消"
   close-on-click-action
   @cancel="onCancel"
   @select="onGenderSelect"
  />
<script>
export default {
 name: "EditUserINfo",
 components: {},
 props: {},
 data() {
  return {
   
   isEditGenderShow: false,
   // name会显示出来，value是我们自己添加的
   actions: [{ name: "男",value: 1 }, { name: "女",value:0 }]
  };
 },
 watch: {},
 computed: {
  
 },
 methods: {
  onGenderSelect(data) {
   this.user.gender=data.value
   this.isEditGenderShow=false
  },
  
 },
 created() {},
 mounted() {}
};
</script>
