Javascript 当我的所有Ng有效时启用一个按钮 回答安全问题 请回答以下问题 *=必填字段 {{问题.问题} 必修的。 继续

ng表格的动态验证 按钮启用并不是验证所有三个必填字段，它的启用取决于最后一个文本区域的必填属性

让我们想象一下，如果您有类似于此表单的内容

 <div ng-show="!login.SecQuestions && !login.ResetUser">
                <h3>Answer security questions</h3>
                <ul>
                    <li>
                        <label>Please answer the following question(s)</label>
                    </li>
                </ul>
                <ul>
                    <li>
                        *= required field
                    </li>
                </ul>

                <ul ng-repeat="Question in login.SecurityQuestions">
                    <li>
                        {{Question.Question}}
                    </li>
                    <li>
                        <ng-form name="SecQuestionForm" novalidate>
                            <textarea name="SecurityAnswer" ng-model="Question.Answer" type="text" required></textarea>
                            <span style="color:red" ng-if="SecQuestionForm.SecurityAnswer.$dirty" ng-show="SecQuestionForm.SecurityAnswer.$invalid">required.</span>
                        </ng-form>
                    </li>
                </ul>

                <ul>
                    <li>
                        <button class="primaryButton" ng-disabled="ResetNamePass.SecQuestionForm.$invalid" ng-click="Continue_2()">Continue</button>
                    </li>
                </ul>
            </div>

希望能有帮助 演示

覆盖的电子邮件：
此电子邮件格式无效

模型：{{myEmail}}

将您的ng表单放入一个表单中，然后添加外部表单有效性的条件on按钮

  <form name="form" class="css-form" novalidate>
  <div>
    Overwritten Email:
    <input type="email" ng-model="myEmail" overwrite-email name="overwrittenEmail" />
    <span ng-show="form.overwrittenEmail.$error.email">This email format is invalid!</span><br>
    Model: {{myEmail}}
    </div>
</form>

继续

只有当所有嵌套的ng表单都有效时，外部表单才有效

<form novalidate name='form1'>
    <ul ng-repeat="Question in login.SecurityQuestions">

AFAICS：在重复中应用formname，在每个条目上产生相同的formname（角度形式）。你有没有尝试过将表单设置在repeat之外？我尝试过将我的表单包装到另一个NG表单中，它起了作用。我认为将表单包装到simple中也会起作用。。所以不需要把它放在ng表格中。是的，我可以这样做，但是我的SPA有几个其他的分区，所以验证一个表格会激发所有d分区的必要性。因此ng表格是唯一的选择。

                        </li>
