vue中使用element-ui进行表单验证的实例代码

<el-form ref="form" :rules="rules" :model="form" label-width="300px">
 <el-form-item label="发货地址：" prop="fAdderss">
 <el-input class="inp" v-model="form.fAdderss" auto-complete="true"></el-input>
 <el-button type="primary" class="btn-add" @click="onSubmit">常用地址</el-button>
 </el-form-item>
 </el-form>

<script>
export default {
 data() {
 return {
 form: {
 fAdderss: '',
 },
 // 校验规则
 rules: {
 fAdderss: [
 { required: true, //是否必填
 message: '地址不能为空', //规则
 trigger: 'blur' //何事件触发
 },
 //可以设置双重验证标准
 { min: 3, max: 5, message: '长度在 3 到 5 个字符', }
 ]
 }
 }
 }
}
</script>

 <el-form ref="form" :rules="rules" :model="form" label-width="300px"> 
 <el-form-item label="发货人电话" prop="phone">
 <el-input class="inp" v-model="form.phone" auto-complete="true"></el-input>
 </el-form-item>
 </el-form>

<script>
export default {
 data() {
 // 此处自定义校验手机号码js逻辑
 var phoneReg = /^[1][3,4,5,7,8][0-9]{9}$/
 var validatePhone = (rule, value, callback) => {
 if (!value) {
 return callback(new Error('号码不能为空!!'))
 }
 setTimeout(() => {
 if (!phoneReg.test(value)) {
 callback(new Error('格式有误'))
 } else {
 callback()
 }
 }, 1000)
 }
 return {
 form: { 
 phone: '',
 },
 // 校验规则
 rules: {
 // 校验手机号码，主要通过validator来指定验证器名称
 phone: [{ required: true, validator: validatePhone, trigger: 'blur' }]
 },
 }
 }
}
</script>
