[JavaScript知识库]vant picker选择器自定义选项内容

前言

项目中遇到需要在选择器中展示多行数据，这里需要用到picker的自定义选项内容。

代码

<template>
  <div class="app-container">
    <van-nav-bar :title="navTitle" />
    <section>
      <van-form @submit="onSubmit">
        <van-field
          readonly
          clickable
          name="picker"
          :value="value"
          label="选择器"
          placeholder="点击选择"
          @click="showPicker = true"
        />
        <van-popup v-model="showPicker" position="bottom">
          <van-picker
            show-toolbar
            :columns="columns"
            value-key="name"
            item-height="56px"
            @confirm="onConfirm"
            @cancel="showPicker = false"
          >
            <template #option="option">
              <div style="display: flex; flex-direction: column; align-items: center;">
                <div>姓名：{{ option.name }}</div>
                <div>年龄：{{ option.age }}</div>
              </div>
            </template>
          </van-picker>
        </van-popup>
        <div style="margin: 16px;">
          <van-button round block type="info" native-type="submit">提交</van-button>
        </div>
      </van-form>
    </section>
  </div>
</template>

<script>
export default {
  name: 'Form',
  data() {
    return {
      navTitle: '表单',
      value: '',
      columns: [{
        name: '张三',
        age: 18
      }, {
        name: '李四',
        age: 19
      }],
      showPicker: false
    }
  },
  methods: {
    onConfirm(value) {
      this.value = value
      this.showPicker = false
    },
    onSubmit(values) {
      console.log('submit', values)
    }
  }
}
</script>

<style lang="less" scoped>
  section {
    padding: 20px;
  }
</style>
