Link-only answers aren't appropriate for SO. By all means reference sources when answering a question, but answer the question within the text of your answer. This keeps SO independent of links that may disappear.

Ok! Didn't realise this, thanks for the info.

Answer 2

+1 A:

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

There's also the dark-magic version: `s = s.replace(/^[^.]*/, '');`

I dont want alert, just need to get it print on page itself

MANnDAaR 2010-06-17 14:36:04

@manndaar - `alert` is an example. You can use `document.write(s)`, but that isn't best practice. It depends where you want it, how you run the script, and if you need it more than once. Please add these details to your question.

Thanx-a-lot Kobi. It worked like charm...

Answer 3

A:

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.

Hope this helps.
