如何抓取第一个swiper-slide
的图片,插入到tt1
类的div中?
仅限第一个.swiper-slide
的图像!
例如:
<div class="tt1"></div>
<div class="ss1">...</div>
<div class="ee1">
<div class="ee2">
<div class="swiper-slide">
<img src="/image1.jpg" style="width: 225px; height: 400px;">
</div>
<div class="swiper-slide">
<img src="/image2.jpg" style="width: 225px; height: 400px;">
</div>
<div class="swiper-slide">
<img src="/image3.jpg" style="width: 225px; height: 400px;">
</div>
</div>
</div>
结果:
<div class="tt1"><img src="/image1.jpg"></div>
<div class="ss1">...</div>
<div class="ee1">
<div class="ee2">
<div class="swiper-slide">
<img src="/image1.jpg" style="width: 225px; height: 400px;">
</div>
<div class="swiper-slide">
<img src="/image2.jpg" style="width: 225px; height: 400px;">
</div>
<div class="swiper-slide">
<img src="/image3.jpg" style="width: 225px; height: 400px;">
</div>
</div>
</div>
或者我可以拍摄第一张图片来形成背景?
<div class="tt1" style="background: url(/image1.jpg);"></div>
<div class="ss1">...</div>
<div class="ee1">
<div class="ee2">
<div class="swiper-slide">
<img src="/image1.jpg" style="width: 225px; height: 400px;">
</div>
<div class="swiper-slide">
<img src="/image2.jpg" style="width: 225px; height: 400px;">
</div>
<div class="swiper-slide">
<img src="/image3.jpg" style="width: 225px; height: 400px;">
</div>
</div>
</div>

您可以使用:
$('.swiper-slide:first img').clone().appendTo('div.tt1')

这将选择类swiper-slide的第一个元素,然后是图像,复制它并将其附加到类tt1的div。生成的HTML是:
<div class="tt1"><img src="/image1.jpg" style="width: 225px; height: 400px;"></div>
<div class="ss1">...</div>
<div class="ee1">
<div class="ee2">
<div class="swiper-slide">
<img src="/image1.jpg" style="width: 225px; height: 400px;">
</div>
<div class="swiper-slide">
<img src="/image2.jpg" style="width: 225px; height: 400px;">
</div>
<div class="swiper-slide">
<img src="/image3.jpg" style="width: 225px; height: 400px;">
</div>
</div>
</div>

要实现此目的,您将使用CSS选择器来定位您的第一个图像,该图像稍后将用作您的jQuery选择器。
您需要使用伪类:first-child
,稍后使用clone()
jQuery方法创建克隆,最后使用该元素将该克隆附加到所需的div
元素appendTo()
方法。
克隆的图像用红色包围。图像克隆并附加为蓝色。

$(".swiper-slide:first-child img").clone().appendTo($(".tt1"));

.tt1 img {
border: 3px solid blue;
display: inline-block;
}
.swiper-slide img {
width: 225px;
height: 400px;

<div class="tt1"></div>
<div class="ss1">...</div>
<div class="ee1">
<div class="ee2">
<div class="swiper-slide">

<div class="swiper-slide">
<img src="http://placehold.it/225x400">

<div class="swiper-slide">

</div>

作为附注 :我建议删除这些内联样式的css属性并在外部css文件中使用它们。
替换样式属性:
style="width: 225px; height: 400px;"
使用:
.ee2 .swiper-slide img {
width: 225px;
height: 400px;
}
(在外部CSS文件中)

您可以使用$('.swiper-slide:eq(1) img').clone().appendTo('div.tt1')
<div class="tt1"></div>
<div class="ss1">...</div>
<div class="ee1">
<div class="ee2">
<div class="swiper-slide">
<img src="/image1.jpg" style="width: 225px; height: 400px;">
</div>
<div class="swiper-slide">
<img src="/image2.jpg" style="width: 225px; height: 400px;">
</div>
<div class="swiper-slide">
<img src="/image3.jpg" style="width: 225px; height: 400px;">
</div>
</div>
</div>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.4/jquery.min.js"></script>
<script>
$('.swiper-slide:eq(1) img').clone().appendTo('div.tt1')
$('.tt1 img').removeAttr('style');
</script>
