jQuery core method overload

Question

how can I overload or extend (or intercept) jQuery's .html() method so that it works its default way unless the object has a certain class?

Thanks

You just overwrite the function while maintaining a reference to the original.

var jq_html_function = $.fn.html;

$.fn.html = function() {
    $(this).each(function() {
        if($(this).hasClass('someclass')) {
            // Do something
            return;
        }
        jq_html_function.apply(this, arguments);
    });
};
