Well, you didn't mention quite a lot, like how do you get your input? What to do if you have no dot, are many dots?
One simple solution is:

var s = 'before.after';
var pos = s.indexOf('.');
if(pos >= 0) // here, if I don't find a dot, keep s as it is.
   s = s.slice(pos);

alert(s); // .after

If the content you want to modify is in HTML content, the easiest way is to do string replace.

Before using replace, you should first locate the content, by its container ID or Name.
