document.body.appendChild(newdiv);
}
newdiv.innerHTML='<imgsrc='+image.src+'width='+(image.width+width)+'height='+(image.height+height)+'/>';
varabsPos=GetAbsPosition(image);
newdiv.style.position="absolute";
newdiv.style.posLeft=absPos[0]-width/2;
newdiv.style.posTop=absPos[1]-height/2;
newdiv.style.display="block";
}
functionHideElement(id)
{
varelem=document.getElementById(id);
elem.style.display="none";
}
</script>
例子：
代码如下:
<body>
<imgsrc="1.jpg"width="300"height="300"onmouseover="ShowFloatingImage(this,150,150);"/>
