我这两天也恰好遇到了扩展element-ui表单验证规则的需求，我翻看了下源代码发现官方没有提供自定义验证规则的办法，只能通过将async-validator源代码放到项目中并重构一下el-form-item来实现，我也顺便解决了一下表单输入项验证以前需要trim一下的问题，这是我写的[demo](https://github.com/liyongleihf2006/extended-elementui-validation-demo),具体步骤在readme中有写，希望能够帮助同样有这个需求的同学

//是不是也要考虑下值是别的类型的情况呀；比如是数组 number 之类的 ```js var entry = { 'a.b.c.dd': 'abcdd', 'a.d.xx': 'adxx', 'a.e': 'ae', 'f.g':["a","b"] } console.log(transform(entry)); function transform(entry){ const target = {}; const map = new Map(); Object.keys(entry).forEach(key=>{ map.set(entry[key],key.split('.'));...
