在javascript上，如何在class属性上不使用同级

我对JS很在行。 我需要使用html代码选择启用了data parent=“16”的元素：

    <div class="filter-options" id="able-filter">
    <div class="Xhaut" id="Xhaut">
    <a class=" active" data-dimension="region" data-filter="all" href="javascript:void(0)">All</a>
    <a data-term_id="18" data-parent="17" data-filter="villebelge1" href="javascript:void(0)" class="a" data-dimension="region">villeBelge1</a>
    <a data-term_id="19" data-parent="17" data-filter="villebelge2" href="javascript:void(0)" class="a" data-dimension="region">villeBelge2</a>
    <a data-term_id="20" data-parent="17" data-filter="villebelge3" href="javascript:void(0)" class="b" data-dimension="region">villeBelge3</a>
    <a data-term_id="21" data-parent="16" data-filter="villenord1" href="javascript:void(0)" class="b" data-dimension="region">villenord1</a>
    <a data-term_id="22" data-parent="16" data-filter="villenord2" href="javascript:void(0)" class="c" data-dimension="region">villenord2</a>
    <a data-term_id="23" data-parent="15" data-filter="villesud1" href="javascript:void(0)" class="c" data-dimension="region">villeSud1</a>
    <a data-term_id="24" data-parent="15" data-filter="villesud2" href="javascript:void(0)" class="d" data-dimension="region">villeSud2</a>
    <a data-term_id="25" data-parent="15" data-filter="villesud3" href="javascript:void(0)" class="d" data-dimension="region">villeSud3</a>

    </div>
    </div>

我拨弄了一下：

太多了

编辑：谢谢你的答案

您可以执行以下操作：

var Xhaut = $('#Xhaut').find('[data-parent=16]');

没有jQuery时：

var Xhaut = document.querySelectorAll('[data-parent="16"]');

---

只需扩展tymeJV的内容，您可以将其缩短一点：

var Xhaut = $('[data-parent=16]','#Xhaut');

var Xhaut = $('[data-parent=16]','#Xhaut');
