HTML5 Support

The aim of HTML5 is to seamlessly provide support an extremely lightweight plugin for a few commonly used html5 attributes for browsers that don't already support them.

HTML5 Support currently supports the placeholder attribute and the autofocus attribute. HTML5 Also supports type=“password” fields, by special casing them, and swapping elements.

Example

HTML

<input type="text" autofocus />
<input type="text" placeholder="Search Here" name="q" />
<input type="password" placeholder="Password" name="pass" />

jQuery

$(document).ready(function() {
  $.html5support();

  // or you can also run only support for what you want
  $.placeholder();
  // - or -
  $.autofocus();
});

CSS

Use this CSS if you would like your placeholder text to show up grey in browsers that do not natively support placeholder.

.placeholder{ color: #888; }

TODO

Support could be added for more HTML5 features. Ideas:

  • <input pattern=“/regex/” />
