                <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>

ng-Form 的动态验证启用该按钮不会验证所有三个必填字段，具体取决于最后一个Textarea的必需字段。

Answer 1

让我们假设你有这样的形式

<form name='form'>
   <input name='name'></input>
   <button ng-disabled='!form.name'></button>
</form>

希望它有所帮助演示Fiddle

Answer 2

将您的ng-form放在一个表单中，然后在按钮上添加条件以获得外部表单的有效性。

<form novalidate name='form1'>
    <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="!form1.$valid" ng-click="Continue_2()">Continue</button>
                        </li>
                    </ul>
</form>

只有当所有嵌套的ng-forms都有效时，

外部表格才有效

  <form name="form" class="css-form" novalidate>
  <div>
    Overwritten Email:
    <input type="email" ng-model="myEmail" overwrite-email name="overwrittenEmail" />

    <button  type="submit" ng-disabled="frmsignIn.$invalid"  >  {{buttonText}}</button>

   </div>
   <div>
    <span ng-show="showErrorMsg">Invalid Email Address/Password.Please try again.</span>
   </div>
    </form>`

我的所有Ng-from都有效时启用一个按钮
