var yOffset = 10; // y distance from mouse
//obj.style.top = (event.clientX + yOffset)+"px";
//obj.style.left = (event.clientY + xOffset)+"px";
//获取元素width: $(obj).width();

//获取元素位置：$(obj).position().top和$(obj).offset().top
$('body').append( '<div id="tipmessage">'+message+'</div>');
$('div#tipmessage').css("top", $(obj).position().top+$(obj).height() + "px").css("left", $(obj).position().left+"px").fadeIn("slow");
}
function HideTip()
{
$("div#tipmessage").fadeOut("slow").remove();
}

<body>
<a href="#" onmouseover="ShowTip(event,this,'欢迎访问PHP中文网')" onmouseout="HideTip()">Tip</a>
