What is the simplest way to create link to Google Map with javascript?

Q. What is the simplest way to create link to Google Map with javascript?
A. Google Map has default url like: http://map.google.com/map?q=your address with sign "+" between words.
For example: address=1234 Some Ave, Somecity, ST 18999.
You need to convert that string to 1234+Some Ave+Somecity+ST+18999.
Simple way: address.replace(/,/g," ").replace(/ /g,"+").
First replace(/,/g," ") will be replaced all(golbal) "," to " ".
Second replace(/ /g,"+") will be replaced all " " to "+".
Final result will be like this: 'http://map.google.com/map?q=1234+Some+ Ave+Somecity+ST+18999'.
