Link Check Regex

I want to make sure there are at least 1 characters before the finial dot, then make sure sure there is atleast 2 characters after the final dot...

link_regex = /^.+\..+$/i;

Doesn't work like that, I thought the .+ would be greedy and grab everything up to the last final dot.

Huh? It works, but not exactly what you said - it will accept one character before and one character after the last dot. You need ^.+\.[^.]{2,}$ for what you described.

link_regex = /^.+\.[^.]{2,}$/i;

[^.] is any non-period character; {2,} says "2 or more".
