Use the Modernizr library, which you can find here: http://www.modernizr.com/

And then do this:

if (Modernizr.input.placeholder) {
  // your placeholder text should already be visible!
} else {
  // no placeholder support :(
  // fall back to a scripted solution
}

Modernizr is really handy for testing the browser's support for almost all HTML5 functionality.
