鼠标经过弹出提示框,用javascript实现

1.javascript文件

document.write("<div id='pup' style='position:absolute; border: 1px solid gray;z-index:1;color:#000000;background-color: #ffffff; width200px;overflow: visible;visibility: hidden;font-size:12px;padding:2px;text-align: left'></div>")

function showpup(str)
{
   var x=event.x;
   var y=event.y;
   pup.innerHTML=str;
   pup.style.visibility="visible";
   pup.style.left=x+10;
   pup.style.pixelTop=y+document.body.scrollTop+10;
}

function hidepup()
{
   pup.style.innerHTML=""
   pup.style.visibility="hidden";
}

2.在连接符号内加入代码

<a href="#"   onMouseMove="showpup('标题:><br>类型:<br>时间:<br>浏览人数：')" onMouseOut='hidepup()'>
