Google Chrome扩展程序javascript打开新标签问题

Question

I'm making an extension for google chrome that allows people put player id in a field and press snap and a new tab will be opened with the url the text that user typed.

Any idea what js codes should I use for the url text in new tab?

Edit: What I did:

I used php instead of js

I used $_Post["name"] but there is problem too!

I need the var to appear only like the person typed it... not with key=var
