Scraping informations from a specific website that is using JavaScript

I want to scrap/extract the informations of this website:
BrickLink

Brick 2 x 4 in Blue

Eric’s…..shop [NEW(118)] (US $0.0825)

Samu…..Brick’s [NEW(116)] (US $0.088)

and so on…

The problem is if I’m using curl or wget I get only the HTML-output.
But this website (is using JavaScript? Ajax? to) get the information afterwards.

Is there a way to scrap the price informations (without using the BrickLink API)?

For example: I want to know who is selling the cheapest >100 items of this Brick (who, the unit-price and how much).

I can’t find anything helpful in the other forum posts either.
