在 Chrome 的下拉菜单中为网页上的特定文本添加书签

如何将网页中属于 Chrome 下拉菜单的特定部分添加为书签？我尝试过将 Chrome 扩展程序链接至 fragment。它不起作用。这是一个网站示例，尝试在单击加油站后将加油站价格添加为书签。

你不能。

该页面设计为以折叠状态加载可折叠面板。您需要单击它们才能展开它们。加载时信息确实存在于页面中，只是隐藏了。如果您使用工具解析 HTML，理论上您可以根据 html 代码提取所需的值。

例子

<span class="gas-type">Regular</span><br>
<span class="h3-style-guide">$2.91<sup>9</sup></span>

和

<span class="gas-type">Premium</span><br>
<span class="h3-style-guide">$3.31<sup>9</sup></span>
