<table id="load" width="700" border="0" align="center" bgcolor="#FAFAFA" cellpadding="0" cellspacing="0" bordercolor="#000000" style="border-collapse:collapse;display:none ">
<tr>
<td><br><br>
<table width="100%" border="1" cellspacing="0" cellpadding="0" bordercolor="#287BCE" style="border-collapse:collapse ">
<tr bgcolor="#F7F7F6">
<td width="20%" height="100" valign="middle">
<table align='center' width='500'>
<tr>
<td colspan='2' align='center' ><font size="2">
正在进行保存，用时较长，请稍后...
</font>
</td>
</tr>
<tr>
<td id='tdOne' height='25' width=1 bgcolor="blue"> </td>
<td id='tdTwo' height='25' width=500 bgColor='#999999'> </td>
</tr>
</table>
</td>
</tr>
</table>
</td>
</tr>
</table>

js:
var speed = 1 ;
var len = 500 ;
var add = 0 ;
function openContenFrame(){
var td1 = document.getElementById('tdOne') ;
var td2 = document.getElementById('tdTwo') ;
add = add+10 ;
td1.width = add ;
if(len - add <= 0){
td2.width = 1 ;
}else{
td2.width = len - add ;
}
if(add<=len) {
;
}else{
td1.width = 1 ;
td2.width = 500 ;
add = 0 ;
}
setTimeout('openContenFrame()',100) ;
}
function loading(){
document.getElementById("load").style.display="";
document.getElementById("opperate").style.display="none";
openContenFrame();
}

在submit()的方法后调用loading()
