regex - How do I replace an asterisk in Javascript using replace()?

Using JQuery, I'm extracting the value from what is essentially a query box for some data in a MySQL database. Knowing that most users will use an '*' (asterisk) as a wildcard value and that MySQL uses the '%' character, I want to convert any asterisks to '%'.

Normally, this would just be as simple as using

queryString = inputText.replace('*', '%');

but I've had little success with that. Javascript's replace() function only replaces the first occurrence, so it's not replacing the last asterisk in something like *Foo*

The second option I tried was using a regular expression, which also didn't work:

queryString = inputText.replace(/x2a/g, '%');

How can I replace the '*' (asterisks) with a '%' (percent sign)? I'd imagine there's a really simple regular expression, or something I'm overlooking.
