Surrogate for repubblica.it

[ginola]

Hi guys,

I can read the website of Italian newspaper Repubblica with scripts disabled with no problem, unless I want to browse their galleries. (example).

As you can see, there's a parameter in the URL pointing to the position of the current picture. I can simply increment that, and it brings me to the next one, so I think the JS is really simple too.

Is somebody able to write a surrogate script that enables browsing galleries?

Thanks!

Code: Select all

for (let a of document.querySelectorAll("a[href^='javascript:show']")) a.href = location.href.replace(/\/(\d+)\/?(?:#|$)/, function(m, s) "/" + (parseInt(s) + (/Next/.test(a.href) ? 1 : -1)))

Thanks Giorgio!

And what should the

Code: Select all

sources

be? I've tried

Code: Select all

@*.repubblica.it

but it didn't work.

Is there a FAQ entry on how to write surrogates?

"@" is for surrogates running on JavaScript enabled pages.

If you want a surrogate to run on a JavaScript disabled page, you need to prepend it with "!",like

Code: Select all

!.repubblica.it

A blog post.

BTW, I slightly adjust the script to handle some edge cases:

Code: Select all

let last = document.head.textContent.match(/\blastPhoto\s*=\s*(\d+)/); last = last && parseInt(last[1]); for (let a of document.querySelectorAll("a[href^='javascript:show']")) a.href = location.href.replace(/\/(\d+)(?=\/?(?:[?#]|$))/, function(m, s) { let n = parseInt(s) + (/Next/.test(a.href) ? 1 : -1); if (n < 1) n = last || 1; else if (last && n > last) n = 1; return "/" + n})
