I’ve written a very simple jQuery function to return a string padded to a specified length, similar to the php equivalent str_pad.
$.strPad = function(i,l,s) {
var o = i.toString();
if (!s) { s = '0'; }
while (o.length < l) {
o = s + o;
}
return o;
};
Example Usage:
$.strPad(12, 5); // returns 00012
$.strPad('abc', 6, '#'); // returns ###abc
This version only supports left padding, which is why it is labelled as only a simple version :).

This is great, there are a lot of PHP-related scripting functions that would be handy if they were accessible in JavaScript – this takes us a step closer!
As you mention, the option to choose which side of the text to pad would also be great 🙂

@Wardy: Thanks 🙂 – There is actually an open source project (PHP.js) available at http://phpjs.org/ that is attempting to port suitable PHP functions to JavaScript.

Thanks a ton for the code. I went ahead and modified & expanded it to act exactly like the php str_pad version:
$.strPad = function(input, pad_length, pad_string, pad_type){
var output = input.toString();
if (!pad_string) { pad_string = ‘ ‘; }
if (pad_type === undefined) { pad_type = ‘STR_PAD_RIGHT’; }
if (pad_type == ‘STR_PAD_RIGHT’) {
while (output.length < pad_length) {
output = output + pad_string;
}
} else if (pad_type == 'STR_PAD_LEFT') {
while (output.length < pad_length) {
output = pad_string + output;
}
} else if (pad_type == 'STR_PAD_BOTH') {
var j = 0;
while (output.length < pad_length) {
if (j % 2) {
output = output + pad_string;
} else {
output = pad_string + output;
}
j++;
}
}
return output;
};

Erg… sorry about the non-indented code. I put it up on github
