直接在绑定事件后添加return false 或 

this.blur()；window.event.returnValue = false;

    </ul>

    <img id="placeholder" src="img/06.png" alt="">
    <p id="description">内容</p>
</body>

js
window.onload=function(){
    function show(whichpic){
        var source=whichpic.getAttribute("href");
        var placeholder=document.getElementById("placeholder");
        placeholder.setAttribute("src",source);
        var text=whichpic.getAttribute("title");
        var description=document.getElementById("description");
        description.firstChild.nodeValue=text;
       
}

    var list=document.getElementById("list");
    var links=list.getElementsByTagName("a");
    for(var i=0;i<links.length;i++){
        links[i].onclick=function(){
            show(this);
            return false;
        // this.blur(); 
        // window.event.returnValue = false;
        }
    }
};
