javascript - 在 DOM 中单击时获取下一个也是唯一一个类

Question

我试图在单击更多信息范围时显示下一个类。

          <span>Total Current Liabilities</span> <span class="more-infos">click</span>
          <input type="text" name="currentratio2"  placeholder="$"></input>
          <p class="more-infos-container">Lorem ipsum dolor sit amet, consectetur adipisicing elit. Laborum eligendi hic minus dicta atque molestiae, qui suscipit </p>
          <span>Total Current Assets</span> <span class="more-infos">click</span>
          <input type="text" name="currentratio1"  placeholder="$"></input>      
          <p class="more-infos-container">Lorem ipsum dolor sit amet, consectetur adipisicing elit. Laborum eligendi hic minus dicta atque molestiae, qui suscipit </p>

理想情况下，当您单击“更多信息”链接时，它将显示与其自身最接近的“更多信息”容器。这是如何实现的？

我尝试使用 next 和 find 以及closest，但它不起作用。

谢谢。

使用.nextAll()方法:

$(function () {
    $('.more-infos').on('click', function (e) {
        var $info = $(this).nextAll('.more-infos-container').eq(0);
        alert($info.html());
    });
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<span>Total Current Liabilities</span> <span class="more-infos">click</span>
<input type="text" name="currentratio2"  placeholder="$"></input>
<p class="more-infos-container">Liabilities Lorem ipsum dolor sit amet, consectetur adipisicing elit. Laborum eligendi hic minus dicta atque molestiae, qui suscipit </p>

<span>Total Current Assets</span> <span class="more-infos">click</span>
<input type="text" name="currentratio1"  placeholder="$"></input>      
<p class="more-infos-container">Assets Lorem ipsum dolor sit amet, consectetur adipisicing elit. Laborum eligendi hic minus dicta atque molestiae, qui suscipit </p>
