当嵌套div为空(包括空白节点)时,我试图隐藏外部div。我找到了一个解决方案,如果没有空格,它可以工作: Hide parent DIV if <li> is Empty
当存在空白区域时,我需要它才能工作,即:
<div class="gen-customer">
<div class="wrapper">
<div class="heading">Hidden if working 1</div>
<div class="content">
<div class="product"> </div>
</div>
</div>
</div>

您可以同时使用:empty
和:contain()
选择器:
$("div.product:contains(' '), div.product:empty").closest('div.wrapper').hide();
希望这有帮助。
$("div.product:contains(' '), div.product:empty").closest('div.wrapper').hide()
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="gen-customer">
<div class="wrapper">
<div class="heading">Hidden if working 1</div>
<div class="content">
<div class="product"> </div>
</div>
</div>
</div>
<div class="gen-customer">
<div class="wrapper">
<div class="heading">Visible if working 2</div>
<div class="content">
<div class="product">text</div>
</div>
</div>
</div>
<div class="gen-customer">
<div class="wrapper">
<div class="heading">Hidden if working 3</div>
<div class="content">
<div class="product"></div>
</div>
</div>

您可以迭代每个div.product
并修剪文本以删除空格。如果剩下任何东西,请显示它,否则,隐藏它的包装。
$("div.product").each(function() {
if ($(this).text().trim() == '') {
$(this).closest('div.wrapper').hide()
}
})
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="gen-customer">
<div class="wrapper">
<div class="heading">Hidden if working 1</div>
<div class="content">
<div class="product"></div>
</div>
</div>
</div>
<div class="gen-customer">
<div class="wrapper">
<div class="heading">Visible if working 2</div>
<div class="content">
<div class="product">text</div>
</div>
</div>
</div>
<div class="gen-customer">
<div class="wrapper">
<div class="heading">Hidden if working 3</div>
<div class="content">
<div class="product"></div>
</div>
</div>
</div>

var element=$('#target_child');
if($(element).html()==''){
$(element).parent().hide()
