similar to my datafill.js gist, uses data attributes instead of DOM id's

datatags.js

datatags = function (dataObject,parentName){
    if(typeof(dataObject) == 'object') {
        for(var item in dataObject) {
            var value = dataObject[item];
            var targetId = parentName ? (parentName + "-" + item) : (item);
            targetId = '[data-'+targetId+']';
            var currentSelection = $(targetId);
            
            if (typeof(value) == 'string' || typeof(value) == 'number' || typeof(value) == 'boolean'){ 

                if (typeof(value) == 'object' && value != null) datatags(value,item);
                
                if (currentSelection.is(':input')){
                    currentSelection.val(value);
                }else{
                    currentSelection.html(value);
                }
            }
        }
    }
};
