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>
</el-table-column>

<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>
</el-table>
</el-form>

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">

<span class="pay-span">医疗服务操作</span>

<div>
<section v-for="(item ,index) in fromData.cchiCombineBill" :key="index">
<p class="tip-p">

<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">

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。
