el-form中的rules未生效的解决方法
宝贝QY 人气:0我们在使用elementUI库的时候，肯定要了解相关的api，但使用过程中明明和官方写法类似为什么自己的就是没有生效，在这里给大家讲解一下我在工作中碰到的一个小问题。
先给大家用图片和代码的形式展示遇到的问题及解决方案：
<el-dialog :visible.sync="dialogVisible" :show-close="false" :title="isEdit?'修改支付商品':'新增支付商品'" width="600px" top="8vh">
<el-form ref="ruleForm" :rules="rules" :model="ruleForm" status-icon label-width="120px" class="demo-ruleForm">
<el-form-item class="payment_item" label="产品名称：" prop="paymentProductName">
<el-input v-model="ruleForm.paymentProductName" size="mini" style="width:350px" placeholder="请输入产品名称"/>
</el-form-item>
<el-form-item class="payment_item" label="产品类型：" prop="paymentProductType">
<el-select v-model="ruleForm.paymentProductType" size="mini" placeholder="请选择" style="width:350px">
<el-option label="小程序开通" value="1"/>
<el-option label="核验币" value="0"/>
</el-select>
</el-form-item>
<el-form-item class="payment_item" label="产品描述：">
<el-input
:rows="2"
v-model="ruleForm.remark"
style="width:350px"
type="textarea"
placeholder="请输入内容"/>
</el-form-item>
<el-form-item class="payment_item" label="价格：" prop="paymentProductPrice">
<el-input-number
:precision="2"
:controls="false"
v-model="ruleForm.paymentProductPrice"
:min="0.01"
size="mini"
style="width:350px"/>
</el-form-item>
<el-form-item class="payment_item" label="数量：" prop="paymentProductNum">
<el-input-number
:precision="0"
:controls="false"
v-model="ruleForm.paymentProductNum"
:min="1"
size="mini"
style="width:350px"/>
</el-form-item>
<el-form-item class="payment_item" label="优惠：" prop="paymentProductGiveNum">
<el-input-number
:precision="0"
:controls="false"
v-model="ruleForm.paymentProductGiveNum"
size="mini"
style="width:350px"/>
</el-form-item>
<el-form-item class="payment_item" label="首充：" prop="isFirstPunch">
<el-radio v-model="ruleForm.isFirstPunch" :label="true">是</el-radio>
<el-radio v-model="ruleForm.isFirstPunch" :label="false">否</el-radio>
</el-form-item>
<el-form-item v-if="ruleForm.isFirstPunch" class="payment_item" label="首充描述标题：" prop="firstPunchTitle">
<el-input v-model="ruleForm.firstPunchTitle" size="mini" style="width:350px" placeholder="请输入首充描述标题" maxlength="15"/>
</el-form-item>
<el-form-item v-if="ruleForm.isFirstPunch" class="payment_item" label="副标题：" prop="firstPunchSubTitle">
<el-input v-model="ruleForm.firstPunchSubTitle" size="mini" style="width:350px" placeholder="请输入副标题" maxlength="30"/>
</el-form-item>
<el-form-item class="payment_item" label="配置渠道：" prop="rechargeChannel">
<el-select v-model="ruleForm.rechargeChannel" size="mini" placeholder="请选择" style="width:350px">
<el-option label="非IOS" value="0"/>
<el-option label="IOS" value="1"/>
</el-select>
</el-form-item>
<el-form-item class="payment_item" label="排序权重：" prop="sort">
<el-input-number :precision="0" :controls="false" v-model="ruleForm.sort" size="mini" style="width:350px"/>
</el-form-item>
</el-form>
<div slot="footer" style="text-align: center">
<el-button @click="dialogVisible = false">取 消</el-button>
<el-button
type="primary"
@click="submitHandler('ruleForm')">确 定
</el-button>
</div>
</el-dialog>data() {
return {
rules: {
paymentProductName: [
{ required: true, message: '请输入产品名称', trigger: 'blur' }
],
paymentProductType: [
{ required: true, message: '请选择产品类型', trigger: 'change' }
],
paymentProductPrice: [
{ required: true, message: '请输入产品价格', trigger: 'blur' }
],
paymentProductNum: [
{ required: true, message: '请输入产品数量' },
{ type: 'number', message: '产品数量必须为数字' }
],
paymentProductGiveNum: [
{ required: true },
{ type: 'number' }
],
isFirstPunch: [
{ required: true, message: '请选择是否是首充', trigger: 'change' }
],
firstPunchTitle: [
{ required: true, message: '请输入首充描述标题', trigger: 'blur' }
],
firstPunchSubTitle: [
{ required: true, message: '请输入副标题', trigger: 'blur' }
],
rechargeChannel: [
{ required: true, message: '请选择配置渠道', trigger: 'change' }
],
sort: [
{ required: true, message: '请输入排序权重' },
{ type: 'number', message: '排序权重必须为数字' }
]
}
}
},特别提醒，<el-form-item>中prop=“paymentProductName”的值一定要跟对应的v-model=“ruleForm.paymentProductName”一致，即两个“paymentProductName”得一样，否则会导致rules失效
