我正在尝试使用aurelia-validation验证问题的可重用文本框组件。在这种情况下,我需要将我的validate属性与其相对名称绑定。这是我使用组件的视图:
<form role="form" validate.bind="model.validation">
<text-field name="firstName" value.two-way="model.firstName" label="First Name :" placeholder="Enter first name"></text-field>
<text-field name="lastName" value.two-way="model.lastName" label="Last Name :" placeholder="Enter last name"></text-field>
查看模型:
import {Validation} from 'aurelia-validation';
import {ClientModel} from '../models/client-model';
export class Registrations{
static inject() { return [Validation]; }
constructor(validation) {
this.heading = 'Registrations';
this.model=new ClientModel('John','Neo','2');
this.readonly = 'readonly';
this.model.validation = validation.on(this.model)
.ensure('firstName')
.isNotEmpty()
.hasMinLength(3)
.hasMaxLength(10)
.ensure('lastName')
.isNotEmpty()
.hasMinLength(5)
.hasMaxLength(10) ;
}
activate () {
}
}
文本字段自定义元素视图:
<div class="editor-field">
<input type="text" value.two-way="value" class="k-textbox" id.one-way="name" placeholder.bind="placeholder" readonly.one-way="readonly" validate="firstName">
</div>
视图模型:
import {bindable} from 'aurelia-framework';
export class TextField {
@bindable name = '';
@bindable value = null;
@bindable id = '';
@bindable label = '';
@bindable placeholder = '';
@bindable readonly = false;
@bindable hasValidationError = false;
@bindable validationMessage = '';
}
它以这种方式工作,但我需要将validate绑定到其正确的名称,所以我尝试了这些方法:
`<input type="text" value.two-way="value" class="k-textbox" id.one-way="name" placeholder.bind="placeholder" readonly.one-way="readonly" validate.bind="name">`
以及字符串插值语法:
<input type="text" value.two-way="value" class="k-textbox" id.one-way="name" placeholder.bind="placeholder" readonly.one-way="readonly" validate="${name}">
但它们不起作用。似乎只接受了一个直接字符串,其中一个字符串位于文本字段自定义元素视图中。如何为每个组件唯一设置验证属性?

我认为你在这里遇到了一些问题,所以这样做,看看你怎么做:
1)验证您的顶级vm
this.validation = validation.on(this)
.ensure('model.firstName')
.isNotEmpty()
.hasMinLength(3)
.hasMaxLength(10)
.ensure('model.lastName')
.isNotEmpty()
.hasMinLength(5)
.hasMaxLength(10) ;
2)告诉验证框架那些验证来自:
<form role="form" validate.bind="validation">
<text-field validate="model.firstName" ...></text-field>
<text-field validate="model.lastName" ...></text-field>
(validate =“model。*”部分可能是不必要的,但也不应该受到伤害)
3)将自定义元素包含在表单组中:
<form role="form" validate.bind="model.validation">
<div class="form-group">
<text-field validate="model.firstName" ...></text-field>
</div>
<div class="form-group">
<text-field validate="model.lastName" ...></text-field>
</div>
