How can I create a Zerofilled value using JavaScript?
I have a number in a variable:
var number = 5;
I need that number to be output as 05:
alert(number); // I want the alert to display 05, rather than 5.
How can I do this?
I could manually check the number and add a 0 to it as a string, but I was hoping there's a JS function that would do it?
This question is related to

numbers
digits
Try this
function pad (str, max) {
return str.length < max ? pad("0" + str, max) : str;
}
alert(pad("5", 2));
Example
Or
var number = 5;
var i;
if (number < 10) {
alert("0"+number);
}
