        var ly=document.getElementById("ly");  
        var obt=document.getElementById("bt");

            var oli =document.createElement("a");  
            oli.innerHTML=tx.value+&#39;删除&#39;+&#39;</br>&#39;;  
            oli.onclick=function ck(){  
                ly.removeChild(this);  
            }  
            oli.href="#";  
            if(ly.firstChild){  
                ly.insertBefore(oli,ly.firstChild);  
            }  
            else{ly.firstChild=oli;}  
            ly.appendChild(oli);  
        };
