Clicking a link on my webpage causes a window to popup which displays an iframe of another webpage of my site.

How do I get an animated preloader gif (already on my server) to display on this iframe window until the contents load?

I can't seem to find the right script for this.

I've done that with just an animated .GIF in a pop-up window, which then closes after the page loads.

Since the ASP is running at the server, and depending on your response.buffer value, may or may not load the entire page upon completion of the script, there's no "Easy" way to do a "Percentage of page loaded" or something like that in ASP that I've found.



Just my 2¢

I have a reporting application that displays "Please Wait" while a report is being built and then when the report data is ready the message disappears and is replaced with the the report.

This is done with the following:


Response.Write("<html>" & vbCR)
Response.Write(" <head>" & vbCR)
Response.Write(" <title>" & ReportTitle & "</title>" & vbCR)
Response.Write(" <script language=""Javascript"">" & vbCR)
Response.Write("<!-- " & vbCR)
Response.Write("if (document.all) { " & vbCR)
Response.Write(" document.write('<span id=w>');" & vbCR)
Response.Write(" document.write('Please wait...');" & vbCR)
Response.Write(" document.write('</span>');" & vbCR)
Response.Write("}" & vbCR)
Response.Write("//-->" & vbCR)
Response.Write(" </script>" & vbCR)
Response.Write(" </head>" & vbCR)
Response.Write(" <body>" & vbCR)

Response.Flush()

'''''''''''''''''''''''''''''''''''''''''''''''''''''''
''''''''''' all the code to build the report ''''''''''

Response.Write(" <script>" & vbCR)
Response.Write(" <!--" & vbCR)
Response.Write(" if (document.all) {" & vbCR)
Response.Write(" document.all(""w"").style.display = 'none';" & vbCR)
Response.Write(" }" & vbCR)
Response.Write(" //-->" & vbCR)
Response.Write(" </script>" & vbCR)
Response.Write(" </body>" & vbCR)
Response.Write("</html>" & vbCR)


You could use the above but replace the "Please wait..." message with your animated gif.

ps - I only have to worry about IE

to which tag do I apply the onload function to? I tried the body tag but it doesn't work

you don't need to put onload anywhere

the second script tag is right at the bottom of the page (just before the </html> tag) so this script executes without calling onload on the body tag

What browser are you using - maybe it is because you are not using IE and document.all("w") is not working??

from all the progress bars that i have seen, this one seems to be the most straight forward and less code. works well with all the browsers.
Code: 
<p>Displays progress bar in status bar and/or in a div in the page as required.</p>

<p><b><font color = "blue"></p>
<div id = "pbar"></div></b></font>

<script type = "text/javascript">
var percent = 10;   // adjust starting value to suit
var timePeriod = 150;  // adjust milliseconds to suit

function getBar() {
var retBar = '';
for (i = 0; i < percent; i++) {
retBar += "|";
}
return retBar;
}

function progressBar() {
if (percent < 100) {
percent = percent + 1;
document.getElementById("pbar").innerHTML = "&nbsp &nbsp &nbsp &nbsp Loading : " + percent + "%" + " " + getBar();
window.status = "Loading : " + percent + "%" + " " + getBar();
setTimeout ("progressBar()", timePeriod);
}
else {
document.getElementById("pbar").innerHTML = "";
window.status = "Your message here";
document.body.style.display = "";
}
}
progressBar();
</script>
i can not take credit for this code since it's not mine. but works well.
