sprintf() for JavaScript that behaves like Python's format (%)?
提问by Rory
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:
我需要一个用于printf/的 JavaScript 函数（或 jQuery 插件）sprintf。它需要支持命名参数 ( "%(foo)s") 和填充 ( "%02d")，即以下格式字符串应该可以工作：
"%(amount)s.%(subunits)02d"
It only needs to support sand 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.
它只需要支持s和d，我不关心其他所有的格式字符串（例如f，x等）。我不需要为字符串填充/ s，只是d，我只需要简单填充d，如%2d，%3d，%04d，等。

Also, dive.into.javascript() has a pageabout sprintf().
此外，dive.into.javascript() 有一个关于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).
PHPJS 项目已经在 Javascript 中实现了很多 PHP 的功能。我无法想象他们为什么要这样做，但事实仍然是他们已经生成了一个sprintf()应该满足您的需求（或至少接近）的实现。
Code for it can be found here: http://phpjs.org/functions/sprintf

Here one function
这里有一个功能
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));
});
