javascript - 当我所有的 Ng-from 都有效时启用一个按钮

Question

 <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>

ng-Form 的动态验证启用按钮不会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要求。

Answer 1

将你的 ng-form 放在一个表单中，然后在按钮上添加外部表单有效性的条件。

<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>

仅当所有嵌套的 ng-forms 都有效时，外部形式才有效
