我已经研究过这个解决方案的Javascript,但我担心我对此的了解太有限了。我猜这个问题的解决方案必须用“节点”来解决,但我无法理解如何 ......
我希望通过更改图像源来绕过以下网站上的图像删除。 Website link
<a href="/music/King+Crimson/In+the+Court+of+the+Crimson+King" class="g3 album-item-cover link-hook" itemprop="url">
<div class="cover-image cover-image--no-content" style="background-image: url('http://cdn.last.fm/flatness/responsive/2/noimage/default_album_300_g4.png');">
<img class="cover-image-image" src="http://cdn.last.fm/flatness/responsive/2/noimage/default_album_300_g4.png" alt="" />
<div class="text-over-image ">
<span class="text-over-image-text">In the Court of the Crimson King</span>
<br/>
<span class="text-over-image-text text-over-image-text--secondary">148,881 listeners</span>
</div>
</div>
</a>
现在我尝试了非常基本的功能,比如'替换'。但我没有得到任何结果。有没有办法根据代码顶部的URL更改以下内容?
示例:
<a href="/music/King+Crimson/URL-A">
...
<img class="cover-image-image" src="http://cdn.last.fm/flatness/responsive/2/noimage/default_album_300_g4.png" alt="" />
...
</a>
<a href="/music/King+Crimson/URL-B">
...
<img class="cover-image-image" src="http://cdn.last.fm/flatness/responsive/2/noimage/default_album_300_g4.png" alt="" />
...
</a>
分为:
<a href="/music/King+Crimson/URL-A">
...
<img class="cover-image-image" src="COVERFORA.JPG" alt="" />
...
</a>
<a href="/music/King+Crimson/URL-B">
...
<img class="cover-image-image" src="COVERFORB.JPG" alt="" />
...
</a>
我为自己提供的小材料道歉,但我只是想知道是否真的有解决方案。 感谢您抽出宝贵时间阅读这篇文章。
干杯!

以下网站的源代码示例:http://www.last.fm/music/King+Crimson/+albums
<a href="/music/King+Crimson/In+the+Court+of+the+Crimson+King" class="g3 album-item-cover link-hook" itemprop="url">
<img src="http://cdn.last.fm/flatness/responsive/2/noimage/default_album_300_g4.png" alt="Album cover for In the Court of the Crimson King" class="rounded" width="220" height="220" />
</a>
<a href="/music/King+Crimson/Red" class="g3 album-item-cover link-hook" itemprop="url">
<img src="http://cdn.last.fm/flatness/responsive/2/noimage/default_album_300_g4.png" alt="Album cover for Red" class="rounded" width="220" height="220" />
</a>
现在,我的想法是将我自己的图像源插入到每个中,但显然它更棘手,因为所有链接都具有默认的相同图像。

$('a.album-item-cover > img.rounded').each(function(e) {
var $this=$(this);
$this.attr('src',this.parentElement.href
.replace(/^.*\/([^\/]+)$/,'Cover_for-$1.jpg'));
}
);
$1
这是最后一个字符串后的字符串

不完全确定你想做什么
var albumCover = document.querySelectorAll('.g3.album-item-cover.link-hook'), // get all links
i = albumCover.length,
a, img,
dict = { // link dictionary, href : src
'/music/King+Crimson/In+the+Court+of+the+Crimson+King' : 'http://photobucket.com/InTheCourt.jpg',
'/music/King+Crimson/Discipline' : 'http://photobucket.com/Discipline.jpg'
};
while( --i >= 0 ) { // loop over each link
a = albumCover[i]; // that link
img = a.getElementsByTagName('img')[0]; // that image
img.src = dict[a.getAttribute('href')] // replace src on that image based on that link
|| img.src; // else no change
}
