Quick Start

The main method you will be dealing with is register. It's basic signature is as follows:

enquire.register(query /* string */, handler /* object || array  || function */);

query is the CSS media query you wish to respond to, and handler is an object containing any logic to handle the query. An example of usage is as follows:

enquire.register("screen and (max-width:1000px)", {      match : function() {},      // OPTIONAL                                 // If supplied, triggered when the media query transitions                                 // *from an unmatched to a matched state*      unmatch : function() {},    // OPTIONAL                                 // If supplied, triggered when the media query transitions                                 // *from a matched state to an unmatched state*.                                 // Also may be called when handler is unregistered (if destroy is not available)      setup : function() {},      // OPTIONAL                                 // If supplied, triggered once immediately upon registration of the handler      destroy : function() {},    // OPTIONAL                                 // If supplied, triggered when handler is unregistered. Place cleanup code here      deferSetup : true           // OPTIONAL, defaults to false                                 // If set to true, defers execution the setup function                                 // until the media query is first matched. still triggered just once });

This should be enough to get you going, but please read the full enquire.js documentation if you wish to learn about the other cool features.

And for all the cool cats who are prepared to give their time to contribute code, feel free to open a pull request. If you could write unit tests to accompany your pull request that would be pretty sweet, but no worries if not - if it's good enough to be merged in, it's good enough for me to spend a little time to write tests on your behalf :-)
