如何从这个标签中获取href链接？

Question

I successfully get href link from http://quotes.toscrape.com/ example by implementing:

response.css('div.quote > span > a::attr(href)').extract()

and it gives all partial link inside href of each a tag:

['/author/Albert-Einstein', '/author/J-K-Rowling', '/author/Albert-Einstein', '/author/Jane-Austen', '/author/Marilyn-Monroe', '/author/Albert-Einstein', '/author/Andre-Gide', '/author/Thomas-A-Edison', '/author/Eleanor-Roosevelt', '/author/Steve-Martin']

by the way in above example each a tag has this format:

<a href="/author/Albert-Einstein">(about)</a>

So I tried to make the same for this site: http://www.thegoodscentscompany.com/allproc-1.html The problem here is that the style of a tag is a bit different as such:

<a href="#" onclick="openMainWindow('http://www.thegoodscentscompany.com/data/rw1247381.html');return false;">formaldehyde</a>

As you see I can't get link from href by using similar method above. I want to get link ( http://www.thegoodscentscompany.com/data/rw1247381.html ) from this a tag, but i could not make it. How can i get this link?

试试这个response.css('a::attr(onclick)').re(r"Window\\('(.*?)'\\)")
