More generically you could use:

x=prompt('enter an integer');
xl=x.toString().length-1
alert((x/Math.pow(10,xl)).toFixed(xl));

(just make sure you enter an integer, preferably +ve, at the prompt)

If you're always dealing with 4 digit numbers, dividing by 1000 will work (as mentioned in another answer) but you'll need to use toFixed to make sure javascript doesn't remove trailing zeros:

var x = 1210;
(x / 1000).toFixed(3) // => "1.210"
(x / 1000) + "" // => "1.21"

Why don't you just divide the number by 1000

var x = 1210;
var y = 1210/1000; //1.210 number
var z = y+"";      // 1.120 will be string here
console.log(y);    // Will output 1.210
