Question

Is there a possibility to wrap each character in Javascript and prepend zero’s if its less then X digits?

What i get/have:

var votes = 2;
//or
var votes = 123;
//or
var votes = 4321;

what it should to look like:

<span>0</span><span>0</span><span>0</span><span>2</span>
//or
<span>0</span><span>1</span><span>2</span><span>3</span>
//or
<span>4</span><span>3</span><span>2</span><span>1</span>

so the result should be a number with four digits.

Answer 1

here’s a tricky version:

var votes = 123;
("0000" + votes).slice(-4); /* 0123 */

thus, to wrap each digit in a <span> you could fetch each digit with $.map and wrap it into its own element, like in this example fiddle: http://jsfiddle.net/cZAWj/

var votes = 973;

$.map(("0000" + votes).slice(-4), function(digit) {
    $('<span/>', { text : digit }).appendTo($('body'));
});
