Find string between two strings in Javascript or jQuery

Question

I have been trying to get a string between two strings in a line. I found a lots of tutorials using regex but as i am not that good at regex, i am not being able to figure out how to do it. Any help will be appreciated.

var fullUrl = "http://something.com/File/?URL=http://www.wireshock.com/&IP=0.0.0.0&CAT=BLOG&USER=MAND\\DEFAULT\\market4080";

i need to figure out a way to get the string between http://something.com/File/?URL= and &IP= and just return http://www.wireshock.com. I dont want to split the strings from "&" and get the middle string as it corrupts some urls with the & character in it. Any help would be appreciated. Thanks :)

Answer 1

fullUrl.match(/URL=(.*?)&/i)[1];

Answer 2

You could use split:

var result = fullUrl.split('http://something.com/File/?URL=')[1].split('&IP=')[0];

Or a regex if you really wanted, but this is pretty brittle though. I would recommend you not do this. Instead, parse the query string properly like a responsible adult:

What if the browser decides to oder things different? Regex or split will break.
