当页装满时,我需要显示“<>载荷”指标。我正在从其他服务器获得页后编码数据,并对名单观点具有约束力。我没有利用更新小组,我也没有通过分析获得数据。因此,我怎么能够显示一个“Loading”指标,因为这个网页需要很长的时间才能装上。

提前感谢。

You create a containing div with a loading gif in the center of it. When you start your ajax request you show it (with jquery for example) when the ajax request is done you hide it.
It could/should look something like this :
Code to show the loading indicator :

 $( #busy-holder ).show();

div:

<div id="busy-holder" style="display: none">
    <div id="busy">

    </div>
</div>

c :

#busy
{
    position: fixed;
    left: 50%;
    top: 50%;
    background: transparent url("loader.gif");
    z-index: 1000;
    height: 66px;
    width: 66px;
}

#busy-holder
{
    height:100%;
    width:100%;
    position:fixed;
    left:0;
    top:0;
    display: none;
    filter: alpha(opacity=30);
    filter: progid:DXImageTransform.Microsoft.Alpha(opacity=30);
    opacity:0.3;
    -moz-opacity: 0.30; 
    z-index: 1000;
}
