hbs:

<div>
  <label> Email: <label>
  {{validated-input model=this placeholder="Enter new email" valuePath='new_email' id="new_email" didValidate=didValidate}}
  <label> Password: <label>
  {{validated-input model=this placeholder="Enter current password" valuePath='current_password' id="current_password" didValidate=didValidate}} 
  <button {{action "changeEmail"}}>Submit</button>
</div>

<div>
  <label> Confirmation Token: <label>
  {{validated-input model=this placeholder="Enter confirmation token" valuePath='confirmation_token' id="confirmation_token" didValidate=didValidate}}
  <button {{action "verify"}}>Verify</button>
</div>

js:

import Ember from 'ember';
import { validator, buildValidations } from 'ember-cp-validations';

const Validations = buildValidations({
  new_email: [
    validator('presence', true),
    validator('format', { type: 'email' })
  ],
  current_password: [
    validator('presence', true)
  ],
  confirmation_token: [
    validator('presence', true),
  ]
});

export default Ember.Component.extend(Validations, {
  changeEmail: function() {
    this.validate().then(() => {
      if (this.get('validations.attrs.new_email.isValid') && this.get('validations.attrs.current_password.isValid')) {
        ...
        ....
      } else {
        this.set('didValidate', true);
      }
  });
});

现在，当我点击提交时，会调用 changeEmail 操作，如果验证失败，它会设置 this.set('didValidate', true) ; 启用所有 三个验证输入 字段并显示甚至 confirmation_token 字段的验证错误。但我只需要为 current_password 和 new_email 显示验证错误消息。当调用 verify 操作时，反之亦然

一种方法是，属性 didValidate

的唯一名称

例如：

<div>
  <label> Email: <label>
  {{validated-input model=this placeholder="Enter new email" valuePath='new_email' id="new_email" didValidate=didValidateEmail}}
  <label> Password: <label>
  {{validated-input model=this placeholder="Enter current password" valuePath='current_password' id="current_password" didValidate=didValidatePassword}} 
  <button {{action "changeEmail"}}>Submit</button>
</div>

<div>
  <label> Confirmation Token: <label>
  {{validated-input model=this placeholder="Enter confirmation token" valuePath='confirmation_token' id="confirmation_token" didValidate=didValidateToken}}
  <button {{action "verify"}}>Verify</button>
</div>

并在 js 中为每个字段手动将属性设置为 true 或 false：

changeEmail: function() {
  this.validate().then(() => {
    if (this.get('validations.attrs.new_email.isValid') && this.get('validations.attrs.current_password.isValid')) {
      ...
      ....
    } else {
      this.setProperties({didValidateEmail: true, didValidatePassword: true});
    }
});

这是唯一的方法吗？

Answer 2

一种方法是在组件上创建一个 didValidate 对象

didValidate: computed(() => ({})),

当你点击else中的changeEmail时你可以

['newEmail', 'currentPassword'].forEach(key => {
  this.set(`didValidate.${key}`, true);
});

它为 didValidate 对象中的每个属性创建一个键并将其设置为 true。

然后在模板中，您可以通过传递

来显示每个字段的错误

didValidate.newEmail or didValidate.currentPassword

仅对选定字段设置 'didValidate' true

set 'didValidate' true only for selected fields
