Try This. This will get you the names of all the classes from all the elements of document.

$(document).ready(function() {
var currentHtml="";
$('*').each(function() {
    if ($(this).hasClass('') === false) {
        var class_name = $(this).attr('class');
        if (class_name.match(/\s/g)){
            var newClasses= class_name.split(' ');
            for (var i = 0; i <= newClasses.length - 1; i++) {
                if (currentHtml.indexOf(newClasses[i]) <0) {
                    currentHtml += "."+newClasses[i]+"
{

}
"
                }
            }
        }
        else
        {
            if (currentHtml.indexOf(class_name) <0) {
                currentHtml += "."+class_name+"
{

}
"
            }
        }
    }
    else
    {
        console.log("none");
    }
});
$("#Test").html(currentHtml);

});
