jquery-common-keys v0.8.0

jquery-common-keys

jQuery collection plugin that triggers events for common accessibility keys, e.g. enter, space, esc, arrows for keydown and keyup events. If you only require keydown events, please use jquery-common-keydown instead.

$(collection).commonKeys();

Experimental

This plugin is still in an experimental state, until it reaches v1.0.0 you must consider all minor releases as breaking changes. Patch releases may introduce new features, but will be backwards compatible. Until v1.0.0 release, please use the caret range specifier in your package.json to pin to a fixed minor version.

Install

npm install jquery-common-keys

    <li><button>Button 1</button></li>

// non-delegated event listener
$('.widget').commonKeys().on('spaceKeyDown enterKeyUp', function(e) {
