采取以下示例
<div id="blog">
<div class="postContent">
<img src="img.png" alt="Keep this one"/>
<img src="img.png" alt="REMOVE this one"/>
<img src="img.png" alt="REMOVE this one"/>
<img src="img.png" alt="REMOVE this one"/>
</div>
<div class="postContent">
<img src="img.png" alt="Keep this one"/>
<img src="img.png" alt="REMOVE this one"/>
<img src="img.png" alt="REMOVE this one"/>
<img src="img.png" alt="REMOVE this one"/>
</div>
<div class="postContent">
<img src="img.png" alt="Keep this one"/>
<img src="img.png" alt="REMOVE this one"/>
<img src="img.png" alt="REMOVE this one"/>
<img src="img.png" alt="REMOVE this one"/>
</div>
</div>
显然我想删除alt所在的图像(尽管生产方式不同)&#34;删除这个&#34;
我尝试过:
$('#blog .postContent img').slice(1).remove(); // AND
$('#blog .postContent img').not(':first').remove();
结果:
<div id="blog">
<div class="postContent">
<img src="img.png" alt="Keep this one"/>
</div>
<div class="postContent">
</div>
<div class="postContent">
</div>
</div>
但是我想要的结果是:
<div id="blog">
<div class="postContent">
<img src="img.png" alt="Keep this one"/>
</div>
<div class="postContent">
<img src="img.png" alt="Keep this one"/>
</div>
<div class="postContent">
<img src="img.png" alt="Keep this one"/>
</div>
</div>
我错过了我确定应该非常简单的事情,非常感谢任何指针

尝试使用:not()
选择器和:first-child
选择器
$('#blog .postContent img:not(:first-child)').remove();
或者您可以使用简单的css
来实现此目的,
#blog .postContent img:not(:first-child){
display:none;
}
