组件库Ant Design Vue,这个组件看起来文档很详细，但也会遇到一些意想不到的问题，遇到的问题主要是当添加input的时候验证不能友好的使用，当一个input添加，然后删除，提交表单的时候会提示填写删除的input，还有个问题就是当把填写好的内容，删除提交的时候，已删除的内容还是能提交到后台，用方法处理
form.getFieldValue('email').splice(index, 1) form.getFieldValue('truename').splice(index, 1) form.setFieldsValue({ keys: keys.filter(key => key !== index), email: form.getFieldValue('email'), truename: form.getFieldValue('truename') })
这样设置的值的时候，数据还是没删除成功，还能提交到后台，后来才知道需要先注册
注册，这样setFieldsValue方法才能成功，但是添加了之后也没删除成功，
this.form.getFieldDecorator('keys', { initialValue: [0], preserve: true }) this.form.getFieldDecorator('email', { initialValue: [], preserve: false }) this.form.getFieldDecorator('truename', { initialValue: [], preserve: false })
经过看代码后来发现文档里面有个没提示到this.form.clearField(’’)，用这个方法总算解决了这个问题。
但是上面方法也有个不好的方法就是，keys在删除的时候不能按顺序排列，造成values数组里面也出现了空字段现象，需要重新处理数组，把字段设置成preserve: false。用对象数组循环数据，用循环的中的索引值组成keys，这样在删除，添加的时候，keys的索引跟values数组一直对应，values数组中不会出现空元素现象，在表单提交的时候加上需要验证的字段，这样问题就解决了，大致的代码如下
<template> <div class="invite-new"> <div class="invite-second-crumb"> <second-crumb /> </div> <div class="invite-box"> <h2>通过邮件邀请，无需审核</h2> <p>发送邀请给指定的邮箱，对方只需进行个人账户设置即可直接加入团队</p> <div class="invite-list"> <a-form ref="inviteForm" layout="inline" :form="form" class="demo-form-inline" @submit.prevent="submitHandle('inviteForm')" > <div v-for="(item,index) in formData" :key="index" class="invite-item" > <a-form-item :required="false" > <div class="input_email"> <a-input v-decorator="[ `email[${index}]`, { validateTrigger: [ 'blur'], rules: [{ required: true, whitespace: true, message: '请输入邮箱' }, { validator: isEmailRe }, { validator:isErrorEmail }, { type:'email', message: '邮箱格式不正确' } ] } ]" placeholder="请输入邮箱" /> </div> </a-form-item> <a-form-item v-if="item.isreg *1 === 1" class="member-name" > <span class="has-register-btn"> 已注册用户 </span> </a-form-item> <a-form-item class="member-name" > <a-input v-decorator="[ `truename[${index}]`,{ rules:[{ required: true, message: '请输入姓名'}] }]" placeholder="姓名" /> </a-form-item> <a-form-item> <a-button v-if="form.getFieldValue('keys').length > 1&&(index!==0)" class="del-invite-btn" @click="delteFormItem(index)" > 删除 </a-button> </a-form-item> </div> <div class="invite-item"> <a-form-item> <a-button class="add-invite-btn" @click="addItem" > 新增 </a-button> </a-form-item> </div> <div class="invite-item"> <a-form-item> <a-button type="primary" html-type="submit" :disabled="loading" > 发送邀请 </a-button> </a-form-item> </div> </a-form> </div> </div> </div> </template> <script> import SecondCrumb from '@/components/pc/organization/invite/SecondCrumb' import { mapActions } from 'vuex' export default { components: { SecondCrumb }, data () { return { initTeamId: '', isLoading: false, submitting: false, initItem: {}, formData: [ { email: '', truename: '', isreg: 0 } ] } }, computed: { loading () { return this.submitting }, args () { return this.$route.query }, keys () { let arr = [] this.formData.forEach((val, index) => { arr.push(index) }) return arr } }, watch: { }, created () { this.form = this.$form.createForm(this) this.form.getFieldDecorator('keys', { initialValue: [], preserve: true }) this.form.getFieldDecorator('email', { initialValue: [], preserve: false }) this.form.getFieldDecorator('truename', { initialValue: [], preserve: false }) }, mounted () { }, methods: { ...mapActions('organization/invite', ['ajaxSave', 'ajaxEmail']), addItem () { this.formData.push( { email: '', truename: '', isreg: 0 } ) const { form } = this form.setFieldsValue({ keys: this.keys }) }, // 删除邀请成员表单行 delteFormItem (index) { const { form } = this // can use data-binding to set this.formData.splice(index, 1) form.getFieldValue('email').splice(index, 1) form.getFieldValue('truename').splice(index, 1) form.setFieldsValue({ keys: this.keys, email: form.getFieldValue('email'), truename: form.getFieldValue('truename') }) }, setFormData (data) { const { formData } = this for (let i = 0; i < data.length; i++) { formData[i].truename = data[i] } }, submitHandle () { this.form.validateFieldsAndScroll(['keys', 'email', 'truename'], async (err, values) => { const { form, formData } = this if (!err) { this.setFormData(form.getFieldValue('truename')) const chain = await this.ajaxSave() chain.params({ cid: this.args.cid * 1, inviteinfo: formData }) .setForm(this.form) .fetch() } }) }, isEmailRe (rule, value, callback) { const length = this.form.getFieldValue('email').filter(item => item === value).length if (length > 1) { callback(new Error('邮箱重复！')) } else { callback() } }, async isErrorEmail (rule, value, callback) { const index = this.form.getFieldValue('email').indexOf(value) const item = this.formData[index] let chain = await this.ajaxEmail() await chain.params({ email: value, cid: this.args.cid }) .onNetSuccess((raw) => { const res = raw.data if (!res.error) { if (res.payload.isreg === 1) { // this.isHasReg = true item.isreg = 1 item.truename = '' } else { item.isreg = 0 } item.email = value } else { // item.msg = res.message // item.isreg = 3 if (value && res.message) { callback(new Error(res.message)) } else { callback() } } }) .fetch() } } } </script>
