What the hell isn't going on?

Who can tell me what's wrong???

This was suposed to eliminate spaces at the beginind and at the end of a string.If there are two spaces they should be eliminated. But why the string "result" remains unchanged?

 

Why not just use something like this?

str = str.replace(/^\s*|\s*$/g,"");

Code (markup):

Not had a long look at your code but what I think you doing is are setting result to a single character each time, and not appending the string.

 

Thanks. But what is that shit?

What shoud I do? Be more clearly.

 

You are not very nice to be asking for help.

I'm getting crazy. I tryed everything.

Everytime I get an empty string as a result.

 

"That shit" is a regular expression that removes all excess spaces at the start and end of the str variable.
