Answer:1

Here's a place to start:

str = "http://mydomain.com/?i=0";
str = str.replace(/((?:\?|&)i=)([^&]*)/g, '$1foo');
Answer:2

Use the javascript replace() function: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String/replace

I'm not going to do the Regex for you as you have demonstrated no attempt at doing it yourself.
