你可以用css做到这一点

<style type="text/css" media="screen">
/* commented backslash hack for ie5mac \*/ 
html, body{height:100%;} 
/* end hack */
.CenterPB{
position: absolute;
left: 50%;
top: 50%;
margin-top: -30px; /* make this half your image/element height */
margin-left: -30px; /* make this half your image/element width */
}
</style>

并且你在div中有进度条

<div class="CenterPB" style="height:60px;width:60px;" >Progress bar here</div>
