I am trying to make a javascript bookmarklet that takes the current page url, modifies the domain to a different one, then opens that in a new tab.
for example, given the url:
https://prod.abc.com/lorum/a-1234/b/c.d/e/1234#fg:hij
I want to run the bookmarklet and have it open
https://dev.abc-1-de.net/lorum/a-1234/b/c.d/e/1234#fg:hij
This is my current code
javascript:(function() {window.open(window.location.toString().replace(/^https:\/\/.*?abc.com\//, 'https://dev.abc-1-de.net/'), '_blank');})()
When I run
window.location.toString().replace(/^https:\/\/.*?abc.com\//, 'https://dev.abc-1-de.net/')
I get the url I'm expecting. However, when I run the whole thing together, the new tab that opens is directed to
https://prod.abc.com/lorum/a-1234/b/c.d/e/https://dev.abc-1-de.net/lorum/a-1234/b/c.d/e/1234#fg:hij.
To me, this seems like the regex is ignoring my ^ anchor for some reason, but I have no idea why that would be happening only when it is passed into window.open.
Turns out, the issue was a typo in the replacement url I was giving, as well as in the way that window.open works. The replacement url I was giving in my unobfuscated code had the typo https//: instead of https:.
This made the window.open function think this was a relative url instead of an absolute, and so it was appending it instead of properly redirecting.
