业务需求：在添加维度时，需要为其动态添加子维度，要求至少一个且名称不能重复，同时进行表单验证。vue页面代码如下：
<template>
<div>
<el-form class="mt10 pd10 elForm" ref="form" :model="form" label-width="130px" :label-position="labelPosition">
<el-form-item label="维度名称：" prop="name" :rules="[
{ required: true, message: '请输入维度名称', trigger: 'blur' }
]">
<el-col :span="8">
<el-input placeholder="请输入维度名称" v-model="form.name"></el-input>
</el-col>
</el-form-item>
<el-form-item label="子维度名称：" >
<el-button size="medium" type="primary" @click="addList" class="btn-min-w">添加</el-button>
</el-form-item>
<el-form-item
v-for="(item,index) in form.list"
:key="index"
:prop="'list.' + index + '.name'"
:rules="{
required: true, message: '请输入子维度名称', trigger: 'blur'
}">
<table>
<tr>
<td>
<el-input v-model="item.name"></el-input>
</td>
<td style="padding-right:0">
<el-button icon="el-icon-minus" type="danger" size="mini" circle @click="delList(index)">
</el-button>
</td>
</tr>
</table>
</el-form-item>
<el-form-item>
<template slot-scope="scope">
<el-button size="medium" type="primary" @click="submit('form')" class="btn-min-w">提交</el-button>
<el-button size="medium" @click="cancel()" class="btn-min-w">返回</el-button>
</template>
</el-form-item>
</el-form>
</div>
</template>
<script>
import tableOperation from '@/components/layout/tableOperation'
import * as api from '@/api/ptms'
import {tips} from '../../static/js/global.js'
export default {
components:{ tableOperation},
data(){
return{
labelPosition: 'right',
form:{
name:'',
list:[
{
name: ''
},
{
name: ''
}
]
}
}
},
created() {
// 跳转页面获取信息
api.dimensionForm({id: this.$route.params.id})
.then((res)=>{
console.log(res);
if(res.ret > -1){
if(this.$route.params.id != null){
this.form.name = res.data.dimension.name;
this.form.list = res.data.subDimension;
// console.log(this.form)
}
}
})
},
methods:{
addList() {
this.form.list.push({name: ''})
},
delList(index) {
if(this.form.list.length === 1){
tips(this, '至少需要一个子维度', 'warning');
return;
}
this.form.list.splice(index, 1)
},
// 添加、修改维度
submit(formName) {
this.$refs[formName].validate((valid) => {
if(valid){
// console.log(this.form.list)
const id = (typeof (this.$route.params.id) === 'undefined') ? null : this.$route.params.id;
let subDimensionsName = this.form.list.map((item) => item.name);
if(isDuplicate(subDimensionsName) === true){
tips(this, '子维度名称不能重复', 'warning');
return;
}
api.dimensionFormAction({id: id, name: this.form.name, subDimensions: this.form.list})
.then((res)=>{
if(res.data === "existed"){
tips(this, '该维度名称已存在', 'warning');
return;
}
tips(this, id == null ? '添加成功！' :'修改成功！', 'success');
this.$router.push('/dimensionList');
})
}
})
},
// 取消返回上一页
cancel() {
this.$router.back(-1);
}
}
}
// 判断子维度是否重复
function isDuplicate(arr) {
let hash = {};
for(let i in arr) {
if(hash[arr[i]]) {
return true;
}
hash[arr[i]] = true;
}
return false;
}
</script>
<style lang="scss" scoped>
</style>
效果如下：
在该项目中，还有一个需求同样用到动态表单，只是不再是文本框，而是变成两个下拉单选框。这里要求前一个下拉框是必选，代码如下：
<template>
<div>
<el-form class="mt10 pd10 elForm" :rules="rules" ref="ruleForm" :model="ruleForm" label-width="130px" :label-position="labelPosition">
<el-form-item label="需求名称：" prop="name">
<el-col :span="8">
<el-input placeholder="请输入需求名称" v-model="ruleForm.name"></el-input>
</el-col>
</el-form-item>
<el-form-item label="创建人员：" prop="createdByName">
<el-col :span="8">
<el-input v-model="ruleForm.createdByName" disabled></el-input>
</el-col>
</el-form-item>
<el-form-item label="负责人：" prop="chargeBy">
<el-col :span="8">
<el-select v-model="ruleForm.chargeBy" placeholder="请选择负责人" @change="chooseOrgs" filterable clearable size="medium">
<el-option v-for="item in orgs" :key="item.id" :label="item.name" :value="item.id"></el-option>
</el-select>
</el-col>
</el-form-item>
<el-form-item label="所属项目：" prop="projectId">
