I'm not sure how to escape '+' in regex. Plus can come multiple times in i so we need to replace all + in the string. Here's what I have:

i.replace(new RegExp(+,g),' ').replace(new RegExp(selectbasic=,g),'').split('&');

But this gives me this error:

Uncaught SyntaxError: Invalid regular expression: /+/: Nothing to repeat

The + character has special significance in regular expressions. It's a quantifier meaning one or more of the previous character, character class, or group.

You need to escape the +, like this:

i.replace(new RegExp(\+,g),' ')...

Or more simply, by using a precompiled expression:

i.replace(/+/g,' ')...
