Aurelia显示每个输入的验证错误

我遇到了在HTML中呈现错误的问题。

视图模型:

import {autoinject} from 'aurelia-framework';
import { ValidationRules, ValidationController, ValidationControllerFactory } from 'aurelia-validation';

// Models
import { NewCustomer } from '../../models/customer';

@autoinject
export class Register {
    controller: ValidationController;
    customer: NewCustomer;

    constructor(controllerFactory: ValidationControllerFactory, customer: NewCustomer) {
        this.controller = controllerFactory.createForCurrentScope();
        this.customer = customer;
        this.controller.addObject(this.customer);
    }

    validate(): void {
        this.controller.validate().then(res => {
            console.log(res);
            if(res.valid) {
                this.register();
            }
        });
    }
}

ValidationRules
    .ensure((c: NewCustomer) => c.first_name).displayName('first name').required().withMessage(`\${$displayName} cannot be blank.`)
    .ensure((c: NewCustomer) => c.last_name).displayName('last name').required().withMessage(`\${$displayName} cannot be blank.`)
    .ensure((c: NewCustomer) => c.email).displayName('first name').email().required().withMessage(`\${$displayName} cannot be blank.`)
    .ensure((c: NewCustomer) => c.phone_number).displayName('phone number').matches(/^\(?([0-9]{3})\)?[-. ]?([0-9]{3})[-. ]?([0-9]{4})$/).withMessageKey('invalid phone number').required().withMessage(`\${$displayName} cannot be blank.`)
    .ensure((c: NewCustomer) => c.password).displayName('password').minLength(7).required().withMessage(`\${$displayName} cannot be blank.`)
    .on(NewCustomer);

和示例输入:

<div class="sb-input-group no-margin" validation-errors.bind="first_nameErrors">
        <label>First Name</label>
        <input value.bind="customer.first_name" placeholder="First Name" class="sb-input-control">
        <span class="help-block danger" repeat.for="errorInfo of first_nameErrors">
            ${errorInfo.error.message}
        <span>
    </div>

现在每当我提交表单并检查控制台时,我都会看到验证规则正在被正确选取;但它们不在视图中渲染。我也尝试过做validation-errors.bind="customer.first_nameErrors"而且也没用。将错误绑定到视图的正确格式是什么?

编辑:这是NewCustomer对象

export class NewCustomer {
    first_name: string;
    last_name: string;
    email: string;
    phone_number: string;
    password: string;
    companies: Company[];
    selected_company_id: string;
}

答案 0 :(得分:2)

看起来你错过了html中的“&amp; validate”标记来向你的验证控制器注册绑定实例。

同时检查验证渲染器(周围有一些Bootstrap Validation Renderers)可以避免在任何地方添加错误范围。

大部分内容都在the docs,但我需要多次通过才能理解这一切!
