为浏览器使用自定义样式 sheet - 如何隐藏 netflix 上的特定节目?

Using Custom Style sheet for browser - How to hide specific shows on netflix?

我最近了解到我们可以使用自定义样式 sheets 来操纵互联网上网站的元素。

我有一个问题,我最终浪费了很多时间在 netflix 上狂看节目,后来我后悔这样做了。所以我想隐藏我上瘾的节目 - 在这种情况下 "Arrow"。

我相信在不久的将来还会有另一个我迷上的,我会用同样的技巧来隐藏它,直到我克服它。

来自 Netflix 的绿箭侠 CSS 是:

<a aria-label="Arrow" class="bob-jaw-hitzone" href="/title/70242081"></a>

它嵌套在几个 div 中,最外面的 div 可能不同,因为节目可以在不同的滑块下多次显示。

我上面提到的这个 CSS 选择器的直接父级是:

<div class="bob-overlay bob-overlay-hidden">
<div class="bob-play-hitzone"></div>
<a aria-label="Arrow" class="bob-jaw-hitzone" href="/title/70242081"></a>
<div class="bob-overview-wrapper">
    <div class="bob-overview">
        <a tabindex="0" data-uia="play-button" role="link" aria-label="Resume" class="bob-play-button playLink" href="/watch/80140962?trackId=14170286&amp;tctx=1%2C0%2Cb9a98838-f436-4b89-ac66-7190b45402e6-32766795%2Ccf1e7866-0b59-41c4-96bd-b10d5ca4cf61_77601417X3XX1581889779290%2Ccf1e7866-0b59-41c4-96bd-b10d5ca4cf61_ROOT">
            <span class="play-button">
                <svg class="svg-icon svg-icon-play-with-ring" focusable="true">
                    <use filter="" xlink:href="#play-with-ring">
                    </use>
                </svg>
            </span>
        </a>
        <div class="bob-title">
            Arrow
        </div>
        <div class="bob-overview-resume-title-wrapper">
        <div class="watched-title watched-title--bob-overview watched-title--no-wrap">
            <span><b>S5:E7</b> "Vigilante"</span>
        </div>
    </div>
    <div class="bob-content-warning-wrapper"></div>
</div>

我尝试在该自定义样式中添加以下内容 sheet 但没有任何区别。

a[aria-label="Arrow"] { display: none; }

关于如何编写匹配和隐藏此节目的 css 选择器有什么建议吗?

听起来您可能想要隐藏包含带有 aria-label="Arrow" 的元素的 整个 bob-overlay 容器。 CSS 不能从 child select 变成 parent,但是你可以用 Javascript 很容易地做到这一点。安装像 Tampermonkey 这样的用户脚本管理器,然后搜索匹配 a[aria-label="Arrow"] 的元素,找到它们的祖先 .bob-overlays,并删除它们(或将它们的显示设置为 none):

for (const a of document.querySelectorAll('a[aria-label="Arrow"]')) {
  a.closest('.bob-overlay').remove();
}
<div class="bob-overlay bob-overlay-hidden">
  arrow - hide me
  <div class="bob-play-hitzone"></div>
  <a aria-label="Arrow" class="bob-jaw-hitzone" href="/title/70242081"></a>
  <div class="bob-overview-wrapper">
    <div class="bob-overview">
      <a tabindex="0" data-uia="play-button" role="link" aria-label="Resume" class="bob-play-button playLink" href="/watch/80140962?trackId=14170286&amp;tctx=1%2C0%2Cb9a98838-f436-4b89-ac66-7190b45402e6-32766795%2Ccf1e7866-0b59-41c4-96bd-b10d5ca4cf61_77601417X3XX1581889779290%2Ccf1e7866-0b59-41c4-96bd-b10d5ca4cf61_ROOT">
        <span class="play-button">
                <svg class="svg-icon svg-icon-play-with-ring" focusable="true">
                    <use filter="" xlink:href="#play-with-ring">
                    </use>
                </svg>
            </span>
      </a>
      <div class="bob-title">
        Arrow
      </div>
      <div class="bob-overview-resume-title-wrapper">
        <div class="watched-title watched-title--bob-overview watched-title--no-wrap">
          <span><b>S5:E7</b> "Vigilante"</span>
        </div>
      </div>
      <div class="bob-content-warning-wrapper"></div>
    </div>
  </div>
</div>

<div class="bob-overlay bob-overlay-hidden">
  not arrow, don't hide me
  <div class="bob-play-hitzone"></div>
  <a aria-label="Foobar" class="bob-jaw-hitzone" href="/title/70242081"></a>
  <div class="bob-overview-wrapper">
    <div class="bob-overview">
      <a tabindex="0" data-uia="play-button" role="link" aria-label="Resume" class="bob-play-button playLink" href="/watch/80140962?trackId=14170286&amp;tctx=1%2C0%2Cb9a98838-f436-4b89-ac66-7190b45402e6-32766795%2Ccf1e7866-0b59-41c4-96bd-b10d5ca4cf61_77601417X3XX1581889779290%2Ccf1e7866-0b59-41c4-96bd-b10d5ca4cf61_ROOT">
        <span class="play-button">
                <svg class="svg-icon svg-icon-play-with-ring" focusable="true">
                    <use filter="" xlink:href="#play-with-ring">
                    </use>
                </svg>
            </span>
      </a>
      <div class="bob-title">
        something else
      </div>
      <div class="bob-overview-resume-title-wrapper">
        <div class="watched-title watched-title--bob-overview watched-title--no-wrap">
          <span><b>S5:E7</b> "Vigilante"</span>
        </div>
      </div>
      <div class="bob-content-warning-wrapper"></div>
    </div>
  </div>
</div>

如果元素是动态加载的并且在初始页面加载时不存在,您可能必须在 setTimeout 或(或 setInterval 轮询后 运行 JS,或 MutationObserver).

整个用户脚本可能看起来像

// ==UserScript==
// @name             Hide Arrow
// @include          https://www.netflix.com/*
// @grant            none
// ==/UserScript==

for (const a of document.querySelectorAll('a[aria-label="Arrow"]')) {
  a.closest('.bob-overlay').remove();
}
