Package Exports

modifiers

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (modifiers) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Modifier key queries

Inspired by keymaster. This is a small subset of the functionality in that library. See for yourself how small it is.

At any point in time you can query the modifiers object to see if a modifier key is held down.

Default supported keys are: shift, alt, option (same as alt), control, command

if (modifiers.command || modifiers.control) {
  // do something special
}

// ..inside your click handler
if (modifiers.shift) {
  ...
}

You can also add your own to the defaults:

modifiers.add({{
  leftArrow: 37,
  upArrow: 38,
  rightArrow: 39,
  downArrow: 40,
  w: 87,
  a: 65,
  s: 83,
  d: 68
});

Building

To create the minified and compressed version with source mapping, run:

uglifyjs modifiers.js --source-map modifiers.min.map --screw-ie8 -c -m -o modifiers.min.js

The code uses addEventListener so if you sadly need to support IE8 you'll want to change the code to use something like what's described here.
