vue element table中自定義一些input的驗(yàn)證操作

更新時(shí)間：2020年07月18日 08:56:51 作者：qianyiyiyi

這篇文章主要介紹了vue element table中自定義一些input的驗(yàn)證操作，具有很好的參考價(jià)值，希望對(duì)大家有所幫助。一起跟隨小編過來看看吧

官網(wǎng)原話

Form 組件提供了表單驗(yàn)證的功能，只需要通過 rules 屬性傳入約定的驗(yàn)證規(guī)則，并將 Form-Item 的 prop 屬性設(shè)置為需校驗(yàn)的字段名即可。

表單

el-form表單必備以下三個(gè)屬性：

:model="ruleForm" 綁定的數(shù)據(jù)內(nèi)容

:rules="rules" 動(dòng)態(tài)綁定的rules，表單驗(yàn)證規(guī)則

ref="ruleForm" 綁定的對(duì)象

template模塊

其實(shí)問題關(guān)鍵就在于如何給el-form-item動(dòng)態(tài)綁定prop

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

<template>
 <div class="TestWorld">
  <el-button @click="addLine">添加行數(shù)</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="書名">
    <template slot-scope="scope">
    <el-form-item :prop="'tableData.' + scope.$index + '.bookname'" :rules='formData.rules.name'>
     <el-input v-model="scope.row.bookname" placeholder="書名" ></el-input>
    </el-form-item>
    </template>
   </el-table-column>
   <el-table-column prop="bookvolume" label="冊(cè)數(shù)">
    <template slot-scope="scope">
     <el-form-item :prop="'tableData.' + scope.$index + '.bookvolume'" :rules="formData.rules.volume1">
     <el-input v-model.number="scope.row.bookvolume" placeholder="冊(cè)數(shù)"></el-input>
     </el-form-item>
    </template>
   </el-table-column>
   <el-table-column prop="bookbuyer" label="購(gòu)買者">
    <template slot-scope="scope">
     <el-form-item :prop="'tableData.' + scope.$index + '.bookbuyer'" :rules='formData.rules.name'>
     <el-input v-model="scope.row.bookbuyer" placeholder="購(gòu)買者"></el-input>
     </el-form-item>
    </template>
   </el-table-column>
   <el-table-column prop="bookborrower" label="借閱者">
    <template slot-scope="scope">
    <el-form-item :prop="'tableData.' + scope.$index + '.bookborrower'" :rules='formData.rules.name'>
     <el-input v-model="scope.row.bookborrower" placeholder="借閱者"></el-input>
    </el-form-item>
    </template>
   </el-table-column>
   <el-table-column prop="bookbuytime" label="購(gòu)買日期">
    <template slot-scope="scope">
    <el-form-item :prop="'tableData.' + scope.$index + '.bookbuytime'" :rules='formData.rules.data1'>
     <el-date-picker
     v-model="scope.row.bookbuytime"
     type="date"
     placeholder="購(gòu)買日期">
     </el-date-picker>
    </el-form-item>
    </template>
   </el-table-column>
   <el-table-column label="操作">
    <template slot-scope="scope">
    <el-button
     size="mini"
     type="danger"
     v-if="!scope.row.editing"
     icon="el-icon-delete"
     @click="handleDelete(scope.$index, scope.row)">刪除
    </el-button>
    </template>
   </el-table-column>
  </el-table>
  </el-form>
 </div>
</template>

vuejs 代碼

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:"冊(cè)數(shù)必須為數(shù)字值",

       },
     data1:{ 
       type:"date",
       required:true,
       message:"請(qǐng)選擇日期",
       trigger:"change"
       }
     },
     tableData:[{
     bookname: '',
     bookbuytime: '',
     bookbuyer: '',
     bookborrower: '',
     bookvolume:''
     }]
    }
  }
 },
 methods:{
  addLine(){ //添加行數(shù)
   var newValue = {
     bookname: '',
     bookbuytime: '',
     bookbuyer: '',
     bookborrower: '',
     bookvolume:''
    };
   //添加新的行數(shù)
   this.formData.tableData.push(newValue);
  },
  handleDelete(index){ //刪除行數(shù)
   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){ //刪除行數(shù)
   console.log(index)
   this.formData.tableData.splice(index, 1)
  }
 }
 
}

補(bǔ)充知識(shí)：element-ui 跟form 和table 動(dòng)態(tài)表單校驗(yàn)，數(shù)組的深層次校驗(yàn)

首先數(shù)據(jù)結(jié)構(gòu)是這樣的

 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">

  <el-divider />
  <el-form ref="mainForm" :model="fromData" class="form-new">
   <section class="pay-section">
    <p class="pay-p">
     <span class="pay-span">醫(yī)療服務(wù)操作</span>
    </p>

      </p>
      <el-table :data="item.cchis" border style="width: 100%;">
       <el-table-column prop="cchiCode" label="CCHI 編碼" min-width="100" />

之前一直是數(shù)組結(jié)合table 一層的校驗(yàn)，琢磨了很久才終于領(lǐng)悟 element-ui 的 form表單校驗(yàn)的精髓所在，

那就是 :prop 一定是遍歷的數(shù)組'cchiCombineBill.' 加上（cchiCombineBill，index）中的index，再加上具體要校驗(yàn)的字段。

以上這篇vue element table中自定義一些input的驗(yàn)證操作就是小編分享給大家的全部?jī)?nèi)容了，希望能給大家一個(gè)參考，也希望大家多多支持腳本之家。
