网页图片提取助手(支持背景图、选择dom范围)

网页图片提取助手(支持背景图、选择dom范围)

网页图片下载工具、网页图片批量保存。

使用场景：

作为web前端开发首——学习小生的你我，仿学在线页面是常有的事，但是一些在线资源，比如图片，图片有img标签中的图片，有背景图，当然还有一些旧浏览器不支持的webp，仿个页面需要 ctrl+m 、 ctrl+s 、查看element、css ...以查找和保存所需图片。

——仿个页面我容易么我？

现在有这个小工具，希望可以助你一点点绵力。

主要应用于以下功能：

一、按需保存所选节点的所有图片

可以选取dom树中的某个元素，保存其中包括背景图的所有图片，小伙伴们再也不用new tag了。

可以选择相应块保存图片的好处是：仿到哪块页面，需要哪些图片，就提取哪些图片。

如果使用浏览器把整个网页一同保存的话文件会非常多，找的时候不好找。按需保存就可避免这个问题。

二、使用 jquery 选择器方便的选择元素节点

没有右键菜单直接选取？

第一，右键菜单选得准备的话还要f12干嘛？

第二，浏览器的API是啥？

三、图片提取到新标签，可以方便使用按钮下载和另存为下载。

把图片提取到新标签，可以预览需要的图片，水平线上的是img中的图片，上平线下的是背景图片。

保存的时候建议使用保存网页的方式（选择保存全部），因为以按钮方式批量下载的话可能下载不全，不知道为啥。

另外，保存时好像 chrome 不支持保存拉出的窗口，怎么破？QQ浏览器可以的，不知道360浏览器啥的可以不。

尴尬了好像虫有点多。

使用方法

复制以下内容到 console 控制台，按回车，输入要提取的dom树选择器，确定即可。
