Is there a JavaScript function that can pad a string to get to a determined length?

Question

I am in need of a JavaScript function which can take a value and pad it to a given length (I need spaces, but anything would do). I found this:

Code:

Answer 1

Here is a simple answer in basically one line of code.

var value = 35 // the numerical value
var x = 5 // the minimum length of the string

var padded = ("00000" + value).substr(-x);

Make sure the number of characters in you padding, zeros here, is at least as many as your intended minimum length. So really, to put it into one line, to get a result of "00035" in this case is:

var padded = ("00000" + 35).substr(-5);
