Extracting a specific part of a URL using regex in JavaScript

Question

I'm fairly new to any kind of language but I need to modify a code at my work because the guy doing it previously left and no replacement.

I basically would like to put in a variable a specific part of a url.

The URLs look like this:

http://www.test.com/abc/hhhhhh/a458/example

I need to extract the a458 part and put it in a variable. This part is always at the same place but can be of variable length.

The URLs always have the same structure. I tried /hhhhhh\/{1}[a-z0-9]+\/{1}/g but it doesn't fully work. It keeps the hhh and the /.

I manage to get that far more or less /hhhhhh\/{1}[a-z0-9]+\/{1}/g but doesn't seem to stripe out the hhh part and both / — user2707774

Please show us the code with which you have applied that regex to the string. What do you mean by "stripe out" for example? — Bergi

no need for regex, just split it

var link = "http://www.test.com/abc/hhhhhh/a458/example";
var linkParts = link.split("/");
//If the link is always in that format then a458 or whatever 
//would replace it will be in index 5
console.log(linkParts[5]);

@user2707774: Yes (unless you're getting example without the query string) and yes
