<nut-cell title="选择地址" :desc="text" is-link @click="showAddress"></nut-cell>
<nut-address
    v-model:show="showPopup"
    :province="province"
    :city="city"

```javascript
setup() {
    const showPopup = ref(false);
    const address = reactive({
      province:[
        { id: 1, name: '北京' },
        { id: 2, name: '广西' },
        { id: 3, name: '江西' },
        { id: 4, name: '四川' }
      ],
      city:[

    const text = ref('请选择地址')

    const showAddress = () => {
      showPopup.value = !showPopup.value;
    };

    const onChange = (cal) => {
      const name = address[cal.next]
      if (name.value.length < 1) {
        showPopup.value = false;
      }
    };
    const close = val => {
      console.log(val);
      text.value = val.data.addressStr;
    };

    return { showPopup, text, showAddress, onChange, close, ...toRefs(address) };
}
```

### 选择已有地址

```html
<nut-cell title="选择地址" :desc="text" is-link @click="showAddressExist"></nut-cell>
<nut-address
    v-model:show="showPopupExist"
    type="exist"
    :existAddress="existAddress"
    @close="close"
    :isShowCustomAddress="false"
    @selected="selected"
    existAddressTitle="配送至"
></nut-address>
```
```javascript
setup() {
    const showPopupExist = ref(false);
    const existAddress = ref([
      {
        id: 1,
        addressDetail: 'th ',
        cityName: '石景山区',
        countyName: '城区',
        provinceName: '北京',
        selectedAddress: true,
        townName: ''
      },{
        id: 2,

        cityName: '电饭锅',
        countyName: '扶绥县',
        provinceName: '北京',

        townName: ''
      },{
        id: 3,
        addressDetail: '发大水比 ',
        cityName: '放到',
        countyName: '广宁街道',
        provinceName: '钓鱼岛全区',
        selectedAddress: false,
        townName: ''
      },{
        id: 4,
        addressDetail: '还是想吧百度吧 ',
        cityName: '研发',
        countyName: '八里庄街道',
        provinceName: '北京',
        selectedAddress: false,
        townName: ''
      }
    ]);

    const text = ref('请选择地址')

    const showAddressExist = () => {
      showPopupExist.value = true;
    };

    const close = val => {
      if (val.type == 'exist') {
        const {provinceName,cityName,countyName,townName,addressDetail} = val.data
        text.value = provinceName + cityName + countyName + townName + addressDetail;
      } else {
        text.value = val.data.addressStr;
      }
    };

    const selected = (prevExistAdd, nowExistAdd, arr) => {
      console.log(prevExistAdd);
      console.log(nowExistAdd);
    };

    return { showPopupExist, existAddress, showAddressExist, text, close, selected };
}
```
### 自定义图标

```html
<nut-cell title="选择地址" :desc="text" is-link @click="showCustomImg"></nut-cell>
<nut-address
    v-model:show="showPopupCustomImg"
    type="exist"
    :existAddress="existAddress"
    @close="close"
    :isShowCustomAddress="false"
    @selected="selected3"
    :defaultIcon="defaultIcon"
    :selectedIcon="selectedIcon"
    :closeBtnIcon="closeBtnIcon"
></nut-address>
```
```javascript
setup() {
    const showPopupCustomImg = ref(false);
    const icon = reactive({
      selectedIcon: 'heart-fill',
      defaultIcon: 'heart1',
      closeBtnIcon: 'close',
      backBtnIcon: 'left'
    });
    const existAddress = ref([
      {
        id: 1,
        addressDetail: 'th ',
        cityName: '石景山区',
        countyName: '城区',

        selectedAddress: false,
        townName: ''
      },{
        id: 4,
        addressDetail: '还是想吧百度吧 ',
        cityName: '研发',
        countyName: '八里庄街道',

    };

    const close = val => {
      if (val.type == 'exist') {
        const {provinceName,cityName,countyName,townName,addressDetail} = val.data
        text.value = provinceName + cityName + countyName + townName + addressDetail;
      } else {
        text.value = val.data.addressStr;
      }
    };

    const selected = (prevExistAdd, nowExistAdd, arr) => {
      console.log(prevExistAdd);
      console.log(nowExistAdd);
    };

    return { showPopupCustomImg, existAddress, text, showCustomImg, close, selected, ...toRefs(icon) };
}
```
