How to store data in an attribute and then parse on click?

My end goal is to be able to send:

$('[data-track]').live('click', function () {
    mpmetrics.track("Share", {'method': 'twitter'});
});

My question is how I can store the Share, method, twitter in the data-bind attribute so that they are dynamic and I can change the variables on any data-track attribute in my app.

<a data-track="XXXXXX" href="#">Tweet</a>

For XXXXXX, how can I set the 3 variables and then parse them in the data-track binding?

You can store any kind of value via .data(). Store the three values as a series of key/value pairs in an object:

$('a').data('track', { key1 : 'value1', key2 : 'value2' });

Fetch it later with

$('a').data('track');

Alternatively, just define them as three data attributes:

<a data-track="XXXXXX" data-key1="value1" data-key2="value2" href="#">Tweet</a>

And access them via .data():

$('a[data-track]').click(function () {
  var $key1 = $(this).data('key1');
  // ...
});

---

<a data-track="Share,method,twitter" href="#">

Then...

var dataTrack = $(this).data('track').split(','); // split by comma

var action    = dataTrack[0];
var values    = {};
values[dataTrack[1]] = dataTrack[2];

mpmetrics.track(action, values);

I think this should be working:

<a id="btn" href="#" data='{"method":"twitter","action":"Share"}'>Test</a>

$('#btn').click(function(){
    var data = jQuery.parseJSON($(this).attr('data'));
});
