IFRAME Load Wait Message

[Guest]

Guys i am runnin into a problem . hope can get solution here .

Page A.cfm calling Page B.cfm through invisible iframe on Click Event of radio bnutton

Code Page A

<script>
function Pop_Drp_dwn(){
AltLoadFrame.document.location = B.cfm?Test='+Val_test;
}
</script>

Hub: <input type="radio" name="All" id="All" class="checkbox" value="Hub" onClick="Pop_Drp_dwn(this.value);">
<select name="origin_hub" id="origin_hub" style="width:150px " class="textbox">
<option value=""></option>
</select>

Page B.cfm will run a Query will get the results in the background and will populate the parent origin_hub select menu dynamically.

Problem: how to dispaly a message or alert or some thing to the user like "Loading / Select Menu loading" while Iframe running a Query and populating Select in the A.cfm ? and that display loading message will go away Once Iframe Done populating.

Many Thanks in Advance .

Never mind I think i did it . For those who do not know . here is the Code
Page A
<script>
var count = 0;
</script>

<script>
function statechange(get){
count++;
var inner = document.getElementById("loadframe");
if (count > 2){
if (get.readyState == 'complete')
{
inner.innerHTML = '';
inner.innerHTML = 'Loaded';
}
else
inner.innerHTML = 'Select Menu Loading Please Wait';
}
}

function Pop_Drp_dwn(Val){
document.frmMyMRS.origin_hub.disabled = true;
AltLoadFrame.document.location = 'sliclist.cfm?pop_drp='+Val+'&Page=Incompatible';
}

</script>

Hub: <input type="radio" name="All" id="All" class="checkbox" value="Hub" onClick="Pop_Drp_dwn(this.value);">
<td>
<select name="origin_hub" id="origin_hub" style="width:150px " class="textbox">
<option value=""></option>
</select> <div id="loadframe"></div></td>

.
<iframe name="AltLoadFrame" width="0" height="0" src="sliclist.cfm" onreadystatechange="statechange(this);"></iframe>

I dont think there is any other esiest way to do this .
Enjoy .
