I need a JavaScript function (or jQuery plugin) for printf/sprintf. It needs to support named arguments ("%(foo)s") and padding ("%02d"), i.e. the following format string should work:
"%(amount)s.%(subunits)02d" It only needs to support s and d, I don't care about all the other format strings (e.g. f, x, etc.). I don't need padding for strings/s, just d, I only need simple padding for d, e.g. %2d, %3d, %04d, etc.
A previous question "Javascript printf/string.format" has some good information.
Also, dive.into.javascript() has a page about sprintf().
The PHPJS project has implemented a lot of PHP's functionality in Javascript. I can't imagine why they'd want to do that, but the fact remains that they have produced a sprintf() implementation which should satisfy your needs (or at least come close).
Code for it can be found here: http://phpjs.org/functions/sprintf
Here one function
var sprintf = function(str) { var args = arguments, flag = true, i = 1; str = str.replace(/%s/g, function() { var arg = args[i++]; if (typeof arg === 'undefined') { flag = false; return ''; } return arg; }); return flag ? str : ''; }; $(document).ready(function() { var msg = 'the department'; $('#txt').html(sprintf('<span>Teamwork in </span> <strong>%s</strong>', msg)); }); <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <center id="txt"></center>
