Is there an equivalent in jQuery to PHP's `preg_replace()`?

Working example here: http://jsfiddle.net/jkeyes/sxx3T/

var re = new RegExp(".*\/(.*)$");
var src="folder/foo/bar/x982j/second822.jpg";
var m = re.exec(src);
alert(m[1]); // first group 

Answer 2

You could use replace() which is like PHP's preg_replace() (it too accepts a PCRE, with some limitations such as no look behinds)...

str.replace(/.*\//, '')

jsFiddle.

Alternatively, you could use...

str.split('/').pop();

jsFiddle.

Answer 3

jQuery is not necessary here; Javascript supports regular expressions on its own, so jQuery is not part of the answer.

Javascript's regex replace function is simply called .replace(), and is a method on the string class. You would use it as follows:

var mystring = 'this is a string';
mystring.replace(/is a/,'might be a');
//mystring is now equal to 'this might be a string'.

That should be enough to get you started. Since you referenced preg_replace() in the question, I assume you already know how to use regular expressions well enough not to need a detailed discussion of how to solve your specific example.
