vue element table中自定义一些input的验证操作

官网原话

Form 组件提供了表单验证的功能，只需要通过 rules 属性传入约定的验证规则，并将 Form-Item 的 prop 属性设置为需校验的字段名即可。

表单

el-form表单必备以下三个属性：

:model="ruleForm" 绑定的数据内容

:rules="rules" 动态绑定的rules，表单验证规则

ref="ruleForm" 绑定的对象

template模块

其实问题关键就在于如何给el-form-item动态绑定prop

:prop="'tableData.' + scope.$index + '.字段名'"

<template>
 <div class="TestWorld">
  <el-button @click="addLine">添加行数</el-button>
  <el-button @click="save('formDom')">baocun</el-button>
  <el-form :rules="formData.rules" :model="formData" ref="formDom" class="demo-ruleForm">
  <el-table
   :data="formData.tableData"
   style="width: 100%">
   <el-table-column prop="bookname" label="书名">
    <template slot-scope="scope">
    <el-form-item :prop="'tableData.' + scope.$index + '.bookname'" :rules='formData.rules.name'>
     <el-input v-model="scope.row.bookname" placeholder="书名" ></el-input>
    </el-form-item>
    </template>
   </el-table-column>
   <el-table-column prop="bookvolume" label="册数">
    <template slot-scope="scope">
     <el-form-item :prop="'tableData.' + scope.$index + '.bookvolume'" :rules="formData.rules.volume1">
     <el-input v-model.number="scope.row.bookvolume" placeholder="册数"></el-input>
     </el-form-item>
    </template>
   </el-table-column>
   <el-table-column prop="bookbuyer" label="购买者">
    <template slot-scope="scope">
     <el-form-item :prop="'tableData.' + scope.$index + '.bookbuyer'" :rules='formData.rules.name'>
     <el-input v-model="scope.row.bookbuyer" placeholder="购买者"></el-input>
     </el-form-item>
    </template>
   </el-table-column>
   <el-table-column prop="bookborrower" label="借阅者">
    <template slot-scope="scope">
    <el-form-item :prop="'tableData.' + scope.$index + '.bookborrower'" :rules='formData.rules.name'>
     <el-input v-model="scope.row.bookborrower" placeholder="借阅者"></el-input>
    </el-form-item>
    </template>
   </el-table-column>
   <el-table-column prop="bookbuytime" label="购买日期">
    <template slot-scope="scope">
    <el-form-item :prop="'tableData.' + scope.$index + '.bookbuytime'" :rules='formData.rules.data1'>
     <el-date-picker
     v-model="scope.row.bookbuytime"
     type="date"
     placeholder="购买日期">
     </el-date-picker>
    </el-form-item>
    </template>
   </el-table-column>
   <el-table-column label="操作">
    <template slot-scope="scope">
    <el-button
     size="mini"
     type="danger"
     v-if="!scope.row.editing"
     icon="el-icon-delete"
     @click="handleDelete(scope.$index, scope.row)">删除
    </el-button>
    </template>
   </el-table-column>
  </el-table>
  </el-form>
 </div>
</template>

vuejs 代码

export default {
 name:'TestWorld',
 data() {
  return {
    formData:{
     rules:{
     name:{ 
       type:"string",
       required:true,
       message:"必填字段",
       trigger:"blur"
       },
     volume1:{ 
        type:"number",
        required:true,
        message:"册数必须为数字值",
        trigger:"change"
       },
     data1:{ 
       type:"date",
       required:true,
       message:"请选择日期",
       trigger:"change"
       }
     },
     tableData:[{
     bookname: '',
     bookbuytime: '',
     bookbuyer: '',
     bookborrower: '',
     bookvolume:''
     }]
    }
  }
 },
 methods:{
  addLine(){ //添加行数
   var newValue = {
     bookname: '',
     bookbuytime: '',
     bookbuyer: '',
     bookborrower: '',
     bookvolume:''
    };
   //添加新的行数
   this.formData.tableData.push(newValue);
  },
  handleDelete(index){ //删除行数
   this.formData.tableData.splice(index, 1)
  },
  save(formName){ //保存
   this.$refs[formName].validate((valid,model) => {
    console.log(valid)
    console.log(JSON.stringify(model))
   if (valid) {
    alert('submit!');
   } else {
    console.log('error submit!!');
    return false;
   }
 
   });
  },
  handleDelete(index){ //删除行数
   console.log(index)
   this.formData.tableData.splice(index, 1)
  }
 }
 
}

补充知识：element-ui 跟form 和table 动态表单校验，数组的深层次校验

首先数据结构是这样的

 let cchiCombineBill = [
   {
    infoId: '1716',
    clinicCchiCombineName: '星期四',
    clinicCchiCombineId: '3',
    serviceCount: '1',
    cchis: [
     {
      cchiCode: 'CAAJ1000'
     },
     {
      cchiCode: 'CAAJ1400'
     }
    ]
   },
   {
    infoId: '1816',
    clinicCchiCombineName: '星期五',
    clinicCchiCombineId: '3',
    serviceCount: '1',
    cchis: [
     {
      cchiCode: 'CAAJ1000'
     },
     {
      cchiCode: 'CAAJ1400'
     }
    ]
   }
  ]

<template>
 <div class="bill-wrapper">
  <p class="title-p">费用调整</p>
  <el-divider />
  <el-form ref="mainForm" :model="fromData" class="form-new">
   <section class="pay-section">
    <p class="pay-p">
     <span class="pay-span">医疗服务操作</span>
    </p>
    <div>
     <section v-for="(item ,index) in fromData.cchiCombineBill" :key="index">

       {{ item.clinicCchiCombineName }}
       <span class="tip-span">（服务数量：{{ item.serviceCount }}）</span>
      </p>
      <el-table :data="item.cchis" border style="width: 100%;">
       <el-table-column prop="cchiCode" label="CCHI 编码" min-width="100" />
       <el-table-column label="调整后支付价格" min-width="160">
        <template slot-scope="scope">
         <el-form-item
          :prop="`cchiCombineBill.${index}.cchis.${scope.$index}.adjustPaymentPrice`"
          :rules="fromData.fromaDataRules.adjustPaymentPrice"
         >

         </el-form-item>

之前一直是数组结合table 一层的校验，琢磨了很久才终于领悟 element-ui 的 form表单校验的精髓所在，

那就是 :prop 一定是遍历的数组'cchiCombineBill.' 加上（cchiCombineBill，index）中的index，再加上具体要校验的字段。

以上这篇vue element table中自定义一些input的验证操作就是小编分享给大家的全部内容了，希望能给大家一个参考，也希望大家多多支持。
