按下span class=val標籤時，顯示懸浮框，內容是span的innerText,鬆開手，懸浮框消失

 var oVal = document.getElementsByClassName('val');
oVal[i].addEventListener("touchstart",  (e)=>{//e就是事件
                if(e.target.offsetWidth==oWidth){
                  th.con = e.target.innerText;
                  th.dialog = true;
                }
              })
              oVal[i].addEventListener("touchend",  (e)=>{
                  th.dialog = false
              })
            }

還有移動事件，touchmove
