clicktap.js

var click_or_tap = function(obj) {
    //for property in obj, add "click " to property and use original value
    var new_obj = {};
    for(var property in obj) {
        if (obj.hasOwnProperty(property)) {
            if (forge.is.mobile()) {
                new_obj["tap " + property] = obj[property];
            }
            else {
                new_obj["click " + property] = obj[property];
            }
