showing progress problem

[dare2win]

Want to indicate progress to user.
Using <div id="progress"> with initial visibility: hidden
Can get "progress" to show with :
[document.getElementById("progress").style.visibility = 'visible';]
that's all good.

But I can't seem to return it to hidden state after request is returned (see function statechanged)

perplexed as always
Thanks


=========snip start ===========
var xmlHttp

function showCustomer(str)
{
document.getElementById("progress").style.visibility = 'visible';
xmlHttp=GetXmlHttpObject();
if (xmlHttp==null)
{
alert ("Your browser does not support AJAX!");
return;
}

var url="getnews.asp";
url=url+"?q="+str;
url=url+"&sid="+Math.random();
xmlHttp.onreadystatechange=stateChanged;
xmlHttp.open("GET",url,true);
xmlHttp.send(null);
}

function stateChanged()
{

if (xmlHttp.readyState==4)
{
if(xmlHttp.status == 200)
{
document.getElementById("txtHint").innerHTML=xmlHttp.responseText;
document.getElementById("progress").style.visibility = 'hidden';
}
}
}

function GetXmlHttpObject()
{
var xmlHttp=null;

try
{
// Firefox, Opera 8.0+, Safari
xmlHttp=new XMLHttpRequest();
}
catch (e)
{
// Internet Explorer
try
{
xmlHttp=new ActiveXObject("Msxml2.XMLHTTP");
}
catch (e)
{
xmlHttp=new ActiveXObject("Microsoft.XMLHTTP");
}
}
return xmlHttp;
}

It would help if you used code tags so the format stayed intact.

Are you sure it is going into the statmenet xmlHttp.status == 200

Have you tried to debug the code using Firebug in firefox or add alert statemenets to see if the code is being called?

yeah I get a 'responsestatus' 200 and 'responsestatustext' "OK" and the object returns everything as it should .... just won't turn off that div content ...aauugh!!

[dare2win]

ok here's an update
moved the script into the document proper...not as an external call (i.e; src="hellscript.js") and it worked.

any insight to why??

I can live with it for now (i will sleep tonight) but would like to have it as an external call eventually.

Thanks Alien51 for replying

Your external js file could have been cached. Clear the cache and see if it works.

[dare2win]

yeah Eric

caching is an issue
have stopped page caching with (asp/vbscript)
response.CacheControl= "no-store"
response.AddHeader "Pragma", "no-cache"
response.expires=-1

but likely still won't prevent a js cache .. correct?

[dare2win]

hmmm, propably I should WANT to cache js for performance issues however.

looking for a perfect world.

[A1ien51]

You want the js files to be cahced. You should add a qs value to the end of the file when you change it.

src="foo.js?ver=213"
