场景

一个页面中tab栏切换多个form表单组件，只有一个保存按钮。需要把各组件下的表达数据合并校验提交。

【实操】vue+element UI tab页多表单合并校验提交

思路

父组件通过两次调用$refs获取子组件的dom元素以及组件内部form的dom元素。
通过循环表单项获取validate值获取校验结果，通过Promise.all合并表单。
子组件内部getData方法返回表单数据，父调用子组件的getData方法获取子组件的表单值

代码

父页面：

<template>
  <div>
    <el-tabs v-model="activeName" type="card" @tab-click="handleClick">
      <el-tab-pane label="form1" name="first">
        <form-comp-one ref="formComp1" />
      </el-tab-pane>
      <el-tab-pane label="form2" name="second">
        <form-comp-two ref="formComp2" />
      </el-tab-pane>
    </el-tabs>
    <el-button class="submit-btn" size="small" @click="submit">提交</el-button>
  </div>
</template>
<script>

       Promise.all([formData1,formData2].map(_this.getFormPromise)).then(res => {
         console.log(res)
           const validateResult = res.every(item => !!item);
