我正在处理一个 html 页面,其中有 div 元素和一个内部 div 元素。在内部 div 元素中有一个图像元素。主div和内div在数字上都是2。

<div class="owl-stage-outer">

<div class="owl-item" style="width: 1903px;"><div class="header-single-slider">
<figure>
<img src="assets/img/sliders/slider01.jpg" alt="">
<figcaption>
<div class="content">
<div class="container inner-content text-left">
<h1 style="display: block;" class="fadeInUp animated">We Build Your<br><span>Business</span> IDEA</h1>
<p style="display: block;" class="fadeInDown animated">There are many variations of passages of Lorem Ipsum available but the majority have suffered injected humour dummy now.</p>
<a href="#" class="boxed-btn fadeInDown animated" style="display: inline-block;">Read More <i class="fas fa-arrow-right"></i></a>
</div>
</div>
</figcaption>
</figure>
</div></div>

<div class="owl-item active" style="width: 1903px;"><div class="header-single-slider">
<figure>
<img src="assets/img/sliders/slider02.jpg" alt="">
<figcaption>
<div class="content">
<div class="container inner-content text-left">
<h1 style="display: block;" class="fadeInUp animated">We Build Your<br><span>Business</span> IDEA</h1>
<p style="display: block;" class="fadeInDown animated">There are many variations of passages of Lorem Ipsum available but the majority have suffered injected humour dummy now.</p>
<a href="#" class="boxed-btn fadeInDown animated" style="display: inline-block;">Read More <i class="fas fa-arrow-right"></i></a>
</div>
</div>
</figcaption>
</figure>
</div></div>
</div>

这里类为'owl-item'的主div被使用了2次,类为'header-single-slider'的内部div也被使用了2次。当程序运行时,类为'owl-item'的主div,它的类变为'owl-item acitve'意味着这个类现在是事件的,第二个div类仍然是'owl-item'。几秒钟后,第二个 div 将变为事件状态,其类变为“owl-item active”,第一个将保持非事件状态,其类将为“owl-item”

我想找到类为“owl-item active”的那个 div 的图像 src。为此,我使用了以下查询:

alert($('.owl-item active').children('div').children("img").attr('src'));

但它显示警告消息为“未定义”。如何解决?

最佳答案

你没有正确选择你的 active owl-item

你可以简单地使用

$('.owl-item.active>div>figure>img').attr('src')

如果您确定您的 div 中只有一个 img,只需使用 '.owl-item.active img' 即可。

console.log($('.owl-item.active>div>figure>img').attr('src'));
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="owl-stage-outer">

<div class="owl-item" style="width: 1903px;">
<div class="header-single-slider">
<figure>
<img src="assets/img/sliders/slider01.jpg" alt="">
<figcaption>
<div class="content">
<div class="container inner-content text-left">
<h1 style="display: block;" class="fadeInUp animated">We Build Your<br><span>Business</span> IDEA</h1>
<p style="display: block;" class="fadeInDown animated">There are many variations of passages of Lorem Ipsum available but the majority have suffered injected humour dummy now.</p>
<a href="#" class="boxed-btn fadeInDown animated" style="display: inline-block;">Read More <i class="fas fa-arrow-right"></i></a>
