我遇到了在HTML中呈現錯誤的問題。Aurelia在輸入時顯示驗證錯誤
視圖模型:
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);
而且與例如輸入:
<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>
現在,每當我提交表單,我檢查我看到驗證規則被拾起正確的控制檯;但是它們不在視圖中呈現。我也試過validation-errors.bind="customer.first_nameErrors"
,也沒有工作。我將錯誤綁定到視圖的正確格式是什麼?
編輯:這裏是NewCustomer對象
export class NewCustomer {
first_name: string;
last_name: string;
email: string;
phone_number: string;
password: string;
companies: Company[];
selected_company_id: string;
}
