I want to truncate a text or line with ellipsis using JavaScript [closed]

Answer 1

KooiInc has a good answer to this. To summarise:

String.prototype.trunc = 
      function(n){
          return this.substr(0,n-1)+(this.length>n?'…':'');
      };

Now you can do:

var s = 'not very long';
s.trunc(25); //=> not very long
s.trunc(5); //=> not...

And if you prefer it as a function, as per @AlienLifeForm's comment:

function truncateWithEllipses(text, max) 
{
    return text.substr(0,max-1)+(text.length>max?'…':''); 
}

Full credit goes to KooiInc for this.
