我想获取具有类assigned-names
但没有名为hidden
的类的span标签的数量。以下是HTML代码:
<div class="assigned-values">
<span class="assigned-names">
<span class="name">Test 1</span>
</span>
<span class="assigned-names hidden">
<span class="name">Test 2</span>
</span>
<span class="assigned-names hidden">
<span class="name">Test 3</span>
</span>
</div>
因此,对于上述HTML,具有类
assigned-names
但没有类hidden
的span标签的数量为1。我试过下面的代码,但它的长度为2:
$('.assigned-values').find('span.assigned-names:not(:has(.hidden))').length
最佳答案
您可以使用not()
函数简单地过滤掉不需要的元素:
const elems = $(".assigned-values > .assigned-names").not(".hidden");
console.log(elems.length);
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="assigned-values">
<span class="assigned-names">
<span class="name">Test 1</span>
</span>
<span class="assigned-names hidden">
<span class="name">Test 2</span>
</span>
<span class="assigned-names hidden">
<span class="name">Test 3</span>
</span>
</div>
