Using sprintf in jQuery [duplicate]

Question

How can I use sprintf in jQuery?

I'm trying to add an id to a chunk of HTML that is returned from a script

So:

success: function(html){ $('.data').html($.sprintf(html,'TEST')); },

The HTML that is returned is a large chunk of HTML where i've added a %s for sprintf to do it's replacement.

Eg: '<div>Welcome to Blah</div><div>You userId is %s</div>'

Here's a sprintf implementation to extend jquery: github.com/azatoth/jquery-sprintf — Matthew Wilcoxson

If it's really as simple as you've described, just use String#replace with a regular expression (so you can use the g flag to make the replacement happen throughout the string):

$('.data').html(html.replace(/%s/g, 'TEST'));

Your solution worked really well. Just for my knowledge, cant sprintf be used in jQuery the way it's done in PHP. EG: sprintf($string,$m)

@Norman: Well, $.sprintf does not exist, so no, you can't use it. But of course you can create your own sprintf implementation and then you can use it.
