Vue代码

Vue.use(VeeValidate);
import { ValidationProvider } from 'vee-validate';
Vue.config.productionTip = false;
Vue.component('ValidationProvider', ValidationProvider);
const emailsDB = ["viveks.nair1988@gmail.com"];

var app = new Vue({
    el: '#updateName',
    mounted() {
        const isUnique = value =>
            new Promise(resolve => {
                setTimeout(() => {
                    if (emailsDB.indexOf(value) === -1) {
                        return resolve({
                            valid: true
                        });
                    }
                    return resolve({
                        valid: false,
                        data: {
                            message: `${value} has already reached out to me!`
                        }
                    });
                }, 200);
            });
        Validator.extend("unique", {
            validate: isUnique,
            getMessage: (field, params, data) => data.message
        });
    }
})
