介绍

组合了级联选择、弹出框组件，实现了便捷快速的级联选择功能。

代码演示

基础使用

使用 v-model 双向绑定当前值，使用 v-model:visible 控制弹出框显隐。

vue ts

<template>
  <s-cascader-popout
    v-model="value"
    v-model:visible="visible"
    title="请选择省市区"
    :options="regionData"
    :field-keys="{ label: 'name', value: 'code' }"
    @change="onChange"
  />

  <s-list card>
    <s-list-item>
      <s-button @click="visible = true">
        {{ value ? value : '请选择' }}
      </s-button>
    </s-list-item>
    <s-list-item
      title="设置为：440111 (广东省/广州市/白云区)"
      arrow
      hover
      @click="value = 440111"
    />
    <s-list-item title="清空" arrow hover @click="value = undefined" />
  </s-list>
</template>

<script setup lang="ts">
import { ref } from 'vue'
import { getRegionData } from 'region-data'
import { type CascaderOption } from 'sard'

const regionData = getRegionData()
const visible = ref(false)
const value = ref<number | undefined>(150102)

const onChange = (value: any, selectedOptions: CascaderOption[]) => {
  console.log('change', value, selectedOptions)
}
</script>

vue js

<template>
  <s-cascader-popout
    v-model="value"
    v-model:visible="visible"
    title="请选择省市区"
    :options="regionData"
    :field-keys="{ label: 'name', value: 'code' }"
    @change="onChange"
  />

  <s-list card>
    <s-list-item>
      <s-button @click="visible = true">
        {{ value ? value : '请选择' }}
      </s-button>
    </s-list-item>
    <s-list-item
      title="设置为：440111 (广东省/广州市/白云区)"
      arrow
      hover
      @click="value = 440111"
    />
    <s-list-item title="清空" arrow hover @click="value = undefined" />
  </s-list>
</template>

<script setup lang="js">
import { ref } from 'vue'
import { getRegionData } from 'region-data'
import 'sard'
const regionData = getRegionData()
const visible = ref(false)
const value = ref(150102)
const onChange = (value, selectedOptions) => {
  console.log('change', value, selectedOptions)
}
</script>

多选

设置 multiple 可进行多选。

vue ts

<template>
  <s-cascader-popout
    v-model="value"
    v-model:visible="visible"
    title="请选择省市区"
    :options="regionData"
    :field-keys="{ label: 'name', value: 'code' }"
    multiple
    all-levels
    check-strictly
    @change="onChange"
  />

  <s-list card>
    <s-list-item
      :title="value ? JSON.stringify(value) : '请选择'"
      arrow
      hover
      @click="visible = true"
    />
    <s-list-item
      title="设置为：[[440000, 440100, 440106], [440000, 440100, 440111]] ([天河区, 白云区])"
      arrow
      hover
      @click="
        value = [
          [440000, 440100, 440106],

        ]
      "
    />
    <s-list-item title="清空" arrow hover @click="value = undefined" />
  </s-list>
</template>

<script setup lang="ts">
