vue实现省份城市选择

发布时间：2019-06-28 09:42编辑：zj 阅读：文章分类：开发互动QQ群：170915747

之前都是后端操作的，城市数据都是存在数据库的，前端选择然后去后端查的，比较简单方便。这次开发的是前端，客户没有提供城市选择的接口，省市这些数据感觉还是放在数据库后端操作较好。

数据和方法也是参考了别人博客的代码，直接贴代码

<!--页面调用组件-->
<atom-city ref="resetCountry"></atom-city>

  
/*写在页面加载方法中，重置选择框中的值*/
this.$refs.resetCountry.reset();

/*写在提交方法中，从组件中获取选择的值*/
var country = that.$refs.resetCountry.changeValueCountry()
var province = that.$refs.resetCountry.changeValueProv()
var city = that.$refs.resetCountry.changeValueCity()

因为有多个页面需要使用，所以把选择城市的封装成atom-city组件，我这个需求是有选择国家的，如果选择的是中国才会有省份城市的选择框，否则用户自己输入省份城市，以下代码参考https://blog.csdn.net/lllo3o/article/details/72955701：
