javascript - 使用 AngularJS 获取 'ng-repeat' 项的索引(计数器)？

Question

我正在使用 AngularJS 及其 ng-repeat 指令来显示一系列问题。我需要从 1 开始为每个问题编号。如何使用 ng-repeat 显示和递增这样的计数器？这是我目前所拥有的:

<ul>
    <li ng-repeat="question in questions | filter: {questionTypesId: questionType, selected: true}">
        <div>
            <span class="name">
                {{ question.questionText }}
            </span>
        </div>
        <ul>
            <li ng-repeat="answer in question.answers">
                <span class="name">
                    {{answer.selector}}. {{ answer.answerText }}
                </span>
            </li>
        </ul>
    </li>
</ul>

Answer 1

Angularjs 文档中有很多示例，您只需要花一些时间来探索它。

请在此处查看此示例:ngRepeat example , 情况相同。

<ul>
    <li ng-repeat="question in questions | filter: {questionTypesId: questionType, selected: true}">
        <div>
            <span class="name">
                {{$index + 1}} {{ question.questionText }}
            </span>
        </div>
        <ul>
            <li ng-repeat="answer in question.answers">
                <span class="name">
                    {{answer.selector}}. {{ answer.answerText }}
                </span>
            </li>
        </ul>
    </li>
</ul>
