Question

Basically, I want to do ‘zipzam&&&?&&&?&&&’ -> ‘zipzam%26%26%26?&&&?&&&’. I can do that without regex many different ways, but it’d cleanup things a tad bit if I could do it with regex.

Thanks

Edit: ‘zip=zam&&&=?&&&?&&&’ -> ‘zip=zam%26%26%26=?&&&?&&&’ should make things a little clearer.

Edit: ‘zip=zam=&=&=&=?&&&?&&&’ -> ‘zip=zam=%26=%26=%26=?&&&?&&&’ should make things clearer.

However, theses are just examples. I still want to replace all ‘&’ before the first ‘?’ no matter where the ‘&’ are before the first ‘?’ and no matter if the ‘&’ are consecutive or not.

Answer 1

This should do it:

'zip=zam=&=&=&=?&&&?&&&'.replace(/^[^?]+/, function(match) { return match.replace(/&/g, '%26'); });
