Javascript regex match for string “game_1”

I’m a big fan of Stack Overflow and I tend to contribute regularly (am currently in the top 0.X%). In this category (stackoverflow) of posts I will will be posting my top rated questions and answers. This, btw, is allowed as explained in the meta thread here.

My question was:

I just can’t get this thing to work in javascript. So, I have a text “game_1” without the quotes and now i want to get that number out of it and I tried this:

var idText = "game_1";
re = /game_(.*?)/;
found = idText.match(re);

var ajdi = found[1];
alert( ajdi );

But it doesn’t work – please point out where am I going wrong.

 The answer, by Naltharial, was:

If you’re only matching a number, you may want to try

/game_([0-9]+)/

as your regular expression. That will match at least one number, which seems to be what you need. You entered a regexp that allows for 0 characters (*) and let it select the shortest possible result (?), which may be a problem (and match you 0 characters), depending on the regex engine.
