How do I URL encode spaces and the word "and"?

Question

I need to URL encode the following characters.

Key	Encoding
Space	%20
and (literal word)	%26

---

To do this, I've come up with the following code. (I need to use var because I'm targeting older browsers.)

var word = "Windows and Mac"; // This can be anything

word = word.split(" ").join("%20");
word = word.split("and").join("%26");

However, there are a few issues with this code.

• This isn't the best solution, and there is most likely a better one available.
• The and is case-sensitive (meaning I can't input "AND", "aNd", etc).

---

Is there another method to fulfill those requirements? It also needs to work on older browsers (like IE).

It doesn't look bad, but is better to use replace, for the and problem just use RegExp:

var word = "Windows and Mac"; // This can be anything

word = word.replace(/\s/g, "%20");
word = word.replace(/and/gmi, "%26");
