UPATE: title is never displayed on load, just on toggle...

wanted to write an update... but there is no jQuery. How can one work without jQuery?

function flexformInit(id){  
                console.log($);        
                /*var $flexsection;
                if(!id){
                    $flexsection = $(".t3-form-field-container-flexsections");
                } else {
                    $flexsection = $("#"+id+"-content");
                }        
                $flexsection.each(function(){
                    id = this.id;
                    var previewContent = "";
                    var $children = $(this).find(".t3-form-field-record-flexsection input");              
                    $children.each(function(){
                        if(this.type=="text" && this.value){
                            previewContent+= (previewContent?" / ":"")+$this.value;
                        }
                    });
                    if (previewContent.length>80)    {
                        previewContent = previewContent.substring(0,67)+"...";
                    }
                    $(id+"-preview").update(previewContent);
                });   */
            }
            flexformInit();
