Aurelia Validation-表单加载了来自获取的数据-Validation将完整字段计算为空
我有一个表单,我成功地从一个获取中加载了数据。如果我在表单上单击save,Aurelia Validation将评估那些数据为空的表单文本字段,并在下面的save按钮下显示为错误-下图 验证在空表单上工作得很好,但对于加载了其值的表单,验证就好像该表单是空的一样 当然,如果文本框中存在通过键入或从提取加载的字符,则应该在required和pass的上下文中对其进行评估 从提取加载时,当前不是 代码 以下是typescript视图模型:Aurelia Validation-表单加载了来自获取的数据-Validation将完整字段计算为空,aurelia,Aurelia,我有一个表单,我成功地从一个获取中加载了数据。如果我在表单上单击save,Aurelia Validation将评估那些数据为空的表单文本字段,并在下面的save按钮下显示为错误-下图 验证在空表单上工作得很好,但对于加载了其值的表单,验证就好像该表单是空的一样 当然,如果文本框中存在通过键入或从提取加载的字符,则应该在required和pass的上下文中对其进行评估 从提取加载时,当前不是 代码 以下是typescript视图模型: import { HttpClient } from

提取在激活函数中,仅当提供了id时才会提取。fetch使用返回的数据加载客户端。这是可行的,我有一个表单,其中显示了提取的所有数据
但是,如果我单击“保存”按钮,即使lastName和mobilePhone这两个字段中都有值,submitClient函数也会触发,this.controller.validate会将这些字段计算为空
它不应该看到这些字段中有值吗?这里有我遗漏的东西吗
以下是视图如何具有lastName-请注意,存在&validate
<div class="col-md-6">
<div class="col-md-3">
<div class="form-group">
<label class="control-label pull-right" for="lastname">Last Name: </label>
</div>
</div>
<div class="col-md-9">
<div class="form-group">
<input type="text" value.bind="client.clientLastName & validate" class="form-control" id="lastname" placeholder="Last Name...">
</div>
</div>
</div>
从服务器加载现有客户端时,将this.client属性设置为简单的JSON对象。它将不再是ClientDetails的实例,因此验证规则将不起作用,因为它们只对ClientDetails实例起作用 您需要创建ClientDetails的新实例,并从fetch返回的数据对象填充它。可以通过在ClientDetails中创建构造函数或映射方法手动完成,该构造函数或映射方法接受数据对象并映射到每个ClientDetails属性this.clientId=data.clientId等
作为替代方案,您可以使用某种类型的通用映射器函数,通过属性名称进行映射。我对TypeScript不太熟悉,但有很多解决方案可以做到这一点。实现了提到的SO问题的选项4,并且成功了。
