注：公司领导要求封装一个区划选择器，最大支持五级区划，并且适用的场景有很多：数据全部由接口所得并且是懒加载形式；能够回显当前登录账号所属级别的默认地址；还能够回显接口返回的默认地址；能够配置区划选择器的最大级别；禁止当前级别之前的地址被选择等等功能，花了两天的事时间，终于算是完善优化好了，供大家一起参考，代码若有缺陷还望指针，感谢！以下是源代码： 特别说明：这里面使用懒加载形式调取接口，每次接口返回一个级别的数据，如第一次默认返回所有省级，点击安徽省，传安徽省code则再次调用接口返回安徽省下所有地级市的数据，依次类推；这里接口返回的数组中，必须要有的参数:[{name:'级别名称',id:'级别code值'}] 技术栈：VUE+ElementUI 组件areaCascader.vue
