HTML5 “placeholder” support

Question

How can I find out if the browser supports the HTML5 placeholder tag, so I can decide whether to hook my jQuery placeholder plugin or not.

Answer 1

To get a broad idea go to:

http://caniuse.com/#search=placeholder

And to test in the browser you can do:

function supportsPlaceholder() {
  var i = document.createElement('input');
  return 'placeholder' in i;
}
