帮看看这样的效果是怎么做的??

效果就是鼠标移到相关记录时候能弹出个框,而且这个框是里的内容是选的,就和你操作另外一个网页一样。怎么实现???

if(hid.value!= " "){
var divObj=document.getElementById(hid.value);
document.body.removeChild(divObj);
}
var newDiv=document.createElement( "div ");
newDiv.id=obj.id+ "_div ";
hid.value=obj.id+ "_div ";
newDiv.innerHTML=obj.innerText+ " <br> aaaaaaaa <br> bbbbbbbbb <br> cccccccccc ";
newDiv.style.position= "absolute ";
newDiv.style.top=event.y;
newDiv.style.left=event.x;
newDiv.style.backgroundColor= "#cccccc ";
document.body.appendChild(newDiv);
}
