Vue+Element-UI 多个form表单验证

Posted 2022-01-04 junechen

在开发的过程中   有时根据业务需求提交的表单内容分区分块  内容繁多 业务控制相对复杂的时候  我们应该将页面内容分成若干个组件  这样方便后期维护查找问题  不然时间长了后期维护找问题头都大了

如上图所示  页面表单分为基本设置，上架设置，更多设置3大块  分别将3大块写到3个组件（A,B,C） 提交表单的时候我们要进行表单验证

思路：利用ES6 Promise异步控制

代码如下

 

 

 

组件A 
<el-form :model="ruleForm" :rules="rules" ref="ruleForm" label-width="100px" class="demo-ruleForm">
     <el-form-item label="套卡名称" prop="name">
    <el-input v-model="ruleForm.name"></el-input>
  </el-form-item>
</el-form>

 

组件B
<el-form :model="ruleForm" :rules="rules" ref="ruleForm" label-width="100px" class="demo-ruleForm">
     <el-form-item label="上架范围" prop="name">
    <el-input v-model="ruleForm.name"></el-input>
  </el-form-item>
</el-form>

组件C
<el-form :model="ruleForm" :rules="rules" ref="ruleForm" label-width="100px" class="demo-ruleForm">
     <el-form-item label="开票" prop="name">
    <el-input v-model="ruleForm.name"></el-input>
  </el-form-item>
</el-form>

 

 

 

html代码如下

<template>
  <div class="product-card-page">
    <!-- basic -->
    <basic
      ref="basic"
      :data="basicInfo"
      :disabled="disabled"
      @deductAmountTypeChange="deductAmountTypeChange" />
    <!-- onshelf -->
    <on-shelf
      ref="onshelf"
      :discount="discount"
      :data="onshelfInfo"
      :tag="tags"
      :disabled="disabled" />
    <!-- more -->
    <more
      ref="more"
      :data="moreInfo"
      :disabled="disabled" />
    <!-- submit -->
    <div
      v-show="!disabled"
      class="btns_row tc mt60 mb50">
      <el-button
        round
        size="mini"
        style="width:78px;"
        @click="$router.push(‘/product/card‘)">
        取消
      </el-button>
      <el-button
        round
        type="primary"
        size="mini"
        style="width:78px;"
        @click="submit">
        保存
      </el-button>
    </div>
  </div>
</template>

 

JS代码如下：

import OnShelf from ‘./components/OnShelf‘

import Basic from ‘./components/Basic‘

import More from ‘./components/More‘

submit()

const p1=new Promise((resolve,reject)=>

this.$refs[‘basic‘].$refs[‘ruleForm‘].validate(valid=>
        if(valid) resolve()
    )
)

const p2=new Promise((resolve,reject)=>
    this.$refs[‘onshelf‘].$refs[‘ruleForm‘].validate(valid=>
        if(valid) resolve()
    )
)


const p3=new Promise((resolve,reject)=>
    this.$refs[‘more‘].$refs[‘ruleForm‘].validate(valid=>
        if(valid) resolve()
    )
)

Promise.all([p1,p2,p3]).then(()=>
   console.log(‘验证通过,提交表单‘) 
    
)
