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"> <p class="tip-p"> {{ 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.$index}.adjustPaymentPrice`" :rules="fromData.fromaDataRules.adjustPaymentPrice" > <el-input v-model="scope.row.adjustPaymentPrice" placeholder="请输入" /> </el-form-item> </template> </el-table-column> </el-table> </section> </div> </section> </el-form> <p class="new-p"> <!-- <el-button type="primary" class="btn" @click="returnFn">返回</el-button> --> <el-button type="primary" class="btn" @click="sureFn">保存</el-button> </p> </div> </template> <script> import { numFixTwo } from '@/utils/tool/regExp' export default { data() { const validateNumFixTwo = (rule, value, callback) => { if (numFixTwo(value)) { callback() } else { callback(new Error('数字,保留小数点后两位')) } } return { fromData: { cchiCombineBill: [], fromaDataRules: { adjustPaymentPrice: [ { required: true, message: '请输入调整后价格', trigger: 'change' }, { required: true, trigger: 'change', validator: validateNumFixTwo } ] } } } }, created() { let cchiCombineBill = [ { infoId: '1716', clinicCchiCombineName: '星期四', clinicCchiCombineId: '3', serviceCount: '1', cchis: [ { cchiCode: 'CAAJ1000' }, { cchiCode: 'CAAJ1400' } ] }, { infoId: '1816', clinicCchiCombineName: '星期五', clinicCchiCombineId: '3', serviceCount: '1', cchis: [ { cchiCode: 'CAAJ1000' }, { cchiCode: 'CAAJ1400' } ] } ] cchiCombineBill.map(item => { let cchis = [] item.cchis.map(item2 => { this.$set(item2, 'adjustPaymentPrice', '') cchis.push(item2) }) item.cchis = cchis this.fromData.cchiCombineBill.push(item) }) }, methods: { getFormPromise(form) { return new Promise(resolve => { form.validate(res => { resolve(res) }) }) }, sureFn() { const mainForm = this.$refs.mainForm // 用户信息 Promise.all( [mainForm].map(this.getFormPromise) // 校验各个表单是否合格 ).then(res => { const validateResult = res.every(item => !!item) if (validateResult) { console.log('表单都校验通过') } else { this.$message({ message: `填写有误,请检查`, type: 'warning' }) } }) } } } </script> <style lang="scss" scoped> .bill-wrapper { min-width: 1110px; margin: 0 auto; padding: 20px; /deep/ .el-divider--horizontal { margin-top: 8px; } // /deep/ .el-form-item { // margin-bottom: 30px; // } .return-p { margin-bottom: 20px; } .new-p { margin-top: 40px; text-align: center; .btn:first-child { margin-right: 30px; } } .pay-section { margin-top: 50px; .pay-p { padding-left: 10px; // border: 1px solid #e8e8e8; height: 30px; line-height: 30px; font-size: 14px; margin-top: 20px; background: #409eff; color: white; } } .sub-title { color: #444; margin-top: 30px; } .tip-p { margin-top: 15px; color: #409eff; font-size: 14px; margin-bottom: 5px; .tip-span { font-size: 12; } } } </style>
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。
