How to trim a string to N chars in Javascript?

by

How can I, using Javascript, make a function that will trim string passed as argument, to a specified length, also passed as argument. For example:

var string = "this is a string";
var length = 6;
var trimmedString = trimFunction(length, string);

// trimmedString should be:
// "this is"

Anyone got ideas? I’ve heard something about using substring, but didn’t quite understand.
