.center_div2
{
position: absolute;
z-index: 1;
text-align: center;
display: none;
background-color: #e0e7ef;
}

.center_div_tips2
{
position: relative;
color: Red;
}
<div id="detailDiv" class="center_div2">
<span class="center_div_tips2"><img src="http://img.VeVB.COm/imgby/loading.gif" alt="" />數據更新中...</span>
</div>

復制代碼代碼如下:

 
function IsIE() { 
var OsObject = ""; 
if (navigator.userAgent.indexOf("MSIE") > 0) { 
return true; 
} 
} 
function mouseMove(ev) { 
/*ie 與ff的event 機制不同*/ 
ev = ev || window.event; 
var mousePos = mouseCoords(ev); 
var detailDiv = document.getElementById("detailDiv"); //將要彈出的層 
detailDiv.style.left = (mousePos.x + 10) + "px"; 
detailDiv.style.top = (mousePos.y + 18) + "px"; 
} 
function mouseCoords(ev) { 
if (ev.pageX || ev.pageY) { 
return { 
x: ev.pageX, 
y: ev.pageY 
}; 
} 
/*ie 與 ff的邊界 處理不同*/ 
if (IsIE()) { 
return { x: ev.clientX + document.documentElement.scrollLeft - document.documentElement.clientLeft, y: ev.clientY + document.documentElement.scrollTop - document.documentElement.clientTop } 
} 
else { 
return { x: ev.clientX + document.body.scrollLeft - document.body.clientLeft, y: ev.clientY + document.body.scrollTop - document.body.clientTop } 
} 
} 
document.onkeydown = keydown;
