smart way to shorten long strings with javascript

I have

<h1>"Very big" page title </h1>

page title and I need to check if character count is bigger than 30, than replace last characters with ...

Can I somehow split text in two parts and replace second part?

Answer 1

Code may be like this:

var text = $('h1').text();
if(text.length > 30)
   $('h1').text(text.sustring(0,30) + "...")

and no need for regexp.
