query-command-supported v1.0.0

document.queryCommandSupported

Polyfill for document.queryCommandSupported that fixes known bugs on Gecko and Blink.

Note: Only copy and cut are polyfill'ed. Any other argument will be executed using the native function.

Install

You can get it on npm.

npm install query-command-supported --save

Or bower, too.

bower install query-command-supported --save

If you're not into package management, just download a ZIP file.

Usage

First, include the script located on the dist folder.

<script src="dist/queryCommandSupported.min.js"></script>

Then, run the queryCommandSupported function as you would normally do.

var isSupported = document.queryCommandSupported('copy');

This will return a boolean that indicates whether or not the command is supported by the browser.
