如何使用 cheerio 获取特定 div 的内联样式？

Question

我正在尝试在 node.js 上使用 cheerio 获取 div 的内联样式（背景图片）。

<div class="">

   </div>

在这个例子中，div with class: "news-card-image" 包含一种内联样式，这是我想要的。如果我可以将整个 div 作为字符串得到，那么也可以，我将操作该字符串并提取背景图像的 url。

Answer 1

那就是：

$('.news-card-image').attr('style')

获取url:

$('.news-card-image').attr('style').match(/'(.*)'/)[1]
