一般很大的表单都会被拆解开，校验，，不会写在一个页面，，就会有多个 el-form ，，主页要集合所有el-form的数据，，所以有一个map来接收，传送表单数据，，map的key就是 ，表单的ref，，，，这样就可以通过遍历map的key来循环校验 el-form，，，

子表单的校验结果返回 boolean值，，使用 every() 每一个都满足返回true，表示校验通过，
通过之后将子表单的 数据，都集中在 formDataMap中，，
子表单的 :data 绑定相同的值 formData，，通过遍历 map的key ，点上相同的 formData属性，就能统一获取子表单的值，，

代码：

<template>
<div>
  <waterkid :waterkid="formDataMap.waterkid" ref="waterkid"></waterkid>
  <hr>
  <cc :cc="formDataMap.cc"  ref="cc"></cc>

  <hr>
  <el-button @click="handleSubmit" >submit </el-button>
  <el-button @click="handleClick">btn</el-button>
</div>
</template>

<script>

export default {

    cc

          address:""
        }
      },
      componentRefs:{}
    }
  },
  mounted() {
    // this.componentRefs.waterkid = this.$refs.waterkid
    // this.componentRefs.cc  =this.$refs.cc
  },
  methods:{
    handleClick(){
      this.$refs["waterkid"].submitForm()
    },
    handleSubmit(){
        var keys = Object.keys(this.formDataMap);

       let validateArr =  keys.map(item=>{

        return  this.$refs[item].submitForm()
        })

      console.log(validateArr,777)
      let validate = validateArr.every(item=>{
        return item
      })

      console.log("validate",validate)

      if (validate){
        // 验证成功
        keys.forEach(item=>{
          this.formDataMap[item] = this.$refs[item].formData
          console.log(this.$refs[item].formData,666)
