Setting countries as disabled/unselectable about jqvmap

[manifestinteractive]

Sounds like a good idea. How would you want to approach this. There is already a way to handle sending data to regions... I could make it so that any region without data gets disabled from clicking. I can make it a setting ( boolean ) to disable regions without data. Your thoughts are welcome ;)

Well, you already have the ability to set the color of specific countries like this:

jQuery('#vmap').vectorMap('set', 'colors', {us: '#0000ff'});

But you also have the global setting "color", and I think this is a little messy, especially when you consider that enabling/disabling clicks is merely one example of many per-region properties that one might want to control, so it would be better to separate them out so that all the properties of regions were singular and could be set both globally and overriden per region in a standardise way that you can extend with new properties in the future.

So how about extending your "set" function to allow setting any property of all or specific regions to one or more values as required using the following 3 syntaxes:

//all regions blue
jQuery('#vmap').vectorMap('set', 'color', '#0000ff');

//US, SO, GR blue
jQuery('#vmap').vectorMap('set', 'color', '#0000ff', 'us,so,gr');

//US blue, SO red, GR green
jQuery('#vmap').vectorMap('set', 'color', {us: '#0000ff', so: '#ff0000', gr: '#00ff00'});

So then for disabling clicking you would just create a new region property "clickEnabled" (with supporting code tweaks elsewhere) and call it like this:

//clicks enabled for all regions
jQuery('#vmap').vectorMap('set', 'clickEnabled', true);

//clicks enabled for all regions which have data
jQuery('#vmap').vectorMap('set', 'clickEnabled', null);

//clicks disabled for US, SO, GR
jQuery('#vmap').vectorMap('set', 'clickEnabled', false, 'us,so,gr');

Seems pretty straight forward. I will work on this for the next version. This would be a handy feature to have.

My pull request #27, among other things, adds a check for isDefaultPrevented() in the regionClick event, allowing a jqvmap client to dynamically allow/suppress clicks on regions, which can be used as one way to solve this problem.
