How to get the input of a TinyMCE editor when using on the front-end?

Ok apparently WordPress keeps track of what kind of editor (visual or html) is active as a class which is added to the content wrapper so here is a solution that will get you the latest content in the editor

function get_tinymce_content(){
    if (jQuery("#wp-content-wrap").hasClass("tmce-active")){
        return tinyMCE.activeEditor.getContent();
    }else{
        return jQuery('#html_text_area_id').val();
    }
}
