根据你提供的代码片段,可以尝试如下修改来实现与 v-model 类似的功能:
<a-col :span="8">
<a-form-item label="商户名称">
<a-select
:allowClear="true"
v-decorator="['merchantName', { rules: [{ required: true, message: '请选择商户名称' }] }]"
placeholder="请选择商户名称"
@change="getServiceName"
>
<a-select-option v-for="item in assetlist" :key="item.merchantName" :value="item.merchantName">
{{ item.merchantName }}
</a-select-option>
</a-select>
</a-form-item>
</a-col>
<a-col :span="8">
<a-form-item label="门店名称" ref="shopName">
<a-select
:allowClear="true"
v-decorator="['shopName', { rules: [{ required: true, message: '请选择门店名称' }] }]"
@change="(value) => shopChange(value, formState.shopName)"
placeholder="请选择门店名称"
>
<a-select-option v-for="item in shoplist" :key="item.shopName" :value="item.shopName">
{{ item.shopName }}
</a-select-option>
</a-select>
</a-form-item>
</a-col>
<script>
export default {
// ...
methods: {
shopChange(value, formShop) {
this.formState.shopName = value;
if (formShop !== value) {
this.$refs.shopName.validateField();
}
console.log(value);
},
// ...
},
};
</script>
上述代码将 v-decorator 添加到 <a-select> 中,并在 shopChange() 方法中更新表单的 formState.shopName 属性。同时,在切换商户时,通过调用 $refs.shopName.validateField() 来触发门店名称字段的校验,以确保选择门店后能够显示相应的错误信息。
希望这可以帮助你解决问题!
