使用Applescript / Javascript从网页选择中获取图像URL /地址

Question

I need a quick way to get the image URL, just like I would get if I right click on an image and select "Copy Image URL". I'm thinking Applescript, though others have mentioned Javascript.

This needs to be compatible with an Automator workflow and needs to work with Google Chrome, Chromium, and Safari, at a minimum.

More specifics:

1. I already have an Automator workflow that this will be added to.
2. The workflow begins with text and images that I have selected on a webpage using the mouse.
3. The processing of the text is working fine.
4. I just need a Applescript or Javascript or Shell Script (which I assume are the only outside code that can be added to an Automator workflow) that will grab any and all image URL's within the part of the page selected in step 2.
5. Images are NOT downloaded. Only the image URL is needed.

The basic logic is this:

Does selected input contain images?
    If yes, 
    get URL of image(s) 
    pass to the next step
else continue

Any help or ideas appreciated!

Answer 1

OS X Services would be your best bet. Those work with text selections and are supported in most apps (eg see the Safari>Services submenu). You can also assign them keyboard shortcuts, which is very handy for repetitive tasks.

Basically, you want to get the selection as web content (ie HTML data, not plain text) then extract the URLs from that. You can create services in Automator, which includes various actions for working with web content, so I recommend starting there.
