I'm trying to reset data attributes after an animation and am running through some trouble applying the technique from answer 2 of this post.
Not sure what I'm missing here. Seems theoretically feasible to say for each data attribute, etc.
UPDATE:
Worth mentioning that the data keys are all different. E.g. data-1="abc", data-2="abc", etc, hence the need for a for loop that simply looks for data attributes.
HTML
var total = 0;    
$.each($('*').data(), function(key, value) {        
    if (key){    
        var thiis = $(this);            
        total += key;            
        thiis.removeData();            
        thiis.data(total, value);
    }
});
                Boom, got it. The script has a lot of overhead, so running it in an instance that a user will wait through isn't an option, IMO. You could improve it with specificity instead of the * selector.
JavaScript (jQuery):
var counter  = 1; // not necessary for your implementation, using it to adjust numeric data keys
$('*').each(function(){ // query all selectors and run through a loop
    var thiis    = $(this),
        dataAttr = thiis.data(),
        i;
    if (dataAttr) { // if the element has data (regardless of attribute)
        var newAttrs = []; // for the element's new data values
        $.each(dataAttr, function(key, value) { // loop through each data object
            var newKey  = key + counter, // calculate new data key
                newAttr = [newKey, value]; // push the new data set
            newAttrs.push(newAttr); // push to elements new attributes array
            thiis
                .removeData(key) // remove the data
                .removeAttr('data-' + key); // remvoe the attribute (unnecessary)
        });
        for (i = 0; i < newAttrs.length; i++) { // for each new attribute
            thiis.data(newAttrs[i][0], newAttrs[i][1]); // add the data
            thiis.attr('data-' + newAttrs[i][0], newAttrs[i][1]); // add the attribute (unnecessary)
        }
    }
});
