Display only 10 characters of a long string?

Question

How do I get a long text string (like a querystring) to display a maximum of 10 characters, using JQuery?

Sorry guys I\'m a novice at JavaScript & JQuery :S

Creating own answer, as nobody has considered that the split might not happened (shorter text). In that case we don't want to add '...' as suffix.

Ternary operator will sort that out:

var text = "blahalhahkanhklanlkanhlanlanhak";
var count = 35;

var result = text.slice(0, count) + (text.length > count ? "..." : "");

Can be closed to function:

function fn(text, count){
    return text.slice(0, count) + (text.length > count ? "..." : "");
}

console.log(fn("aognaglkanglnagln", 10));

And expand to helpers class so You can even choose if You want the dots or not:

function fn(text, count, insertDots){
    return text.slice(0, count) + (((text.length > count) && insertDots) ? "..." : "");
}

console.log(fn("aognaglkanglnagln", 10, true));
console.log(fn("aognaglkanglnagln", 10, false));
