不知道為什么。頁面一刷新就顯示了“請輸入密碼”，代碼如下：
html部分：

<div class="reg-group reg-pass">
    <label for="pass">密&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;碼：</label>
    <input type="text" id="pass" v-model="pass" :class="{'error':$v.pass.$error}" @blur="$v.pass.$touch()">
    <span v-show="!$v.pass.required">請輸入密碼</span>
    <span v-show="!$v.pass.minLength || !$v.pass.maxLength">密碼應(yīng)該為6~16位</span>
</div>

<div class="reg-group reg-sure-pass">
    <label for="sure-pass">確認(rèn)密碼：</label>
    <input type="text" id="sure-pass" v-model="surePass" @blur="$v.surePass.$touch()">
    <span v-show="!$v.surePass.required">請再次輸入密碼</span>
    <span v-show="!$v.surePass.sameAs">與上面輸入密碼不一致</span>
</div>

js部分：

import {required, minLength, maxLength, between, sameAs} from 'vuelidate/lib/validators';
export default {
    name: "vuelidate-pri",
    data (){
        return {
            flag: '',
            name: '',
            user: '',
            age: '',
            pass: '',
            surePass: '',
            phone: '',
            status: ''
        };
    },
    validations: {
        pass: {
            required,
            minLength: minLength(6),
            maxLength: maxLength(16)
        },
        surePass: {
            required,
            sameAs: sameAs('pass')
        },
        phone: {

        }
    }
}

頁面一刷新就是這樣，急急急，求大神！
