How to delay a frame load

nachetex · #1 (**permalink**) 06-27-03, 05:25 AM

I have a page with two frames, frame A makes a connection with a database and fills a Session variable with data, this Session var is then used in frame B two to show the data. The problem is that when the connection to internet is slow it seems that frame A takes long time to finish load and the data is not shown in frame B

Since your using ASP it would be a lot more efficient to use includes instead of frames.

Other than that since ive never had to do somethin like this before you could you could put the scripting in the actual frameset page

hello
i foun this one somewhere

is a preloading with an iframe
but you can modelate to your needs

PHP Code:


			
<html>

<head>

<title>How to Pre-load an HTML Page</title>



<script type="text/javascript">

function Is() {

    agent  = navigator.userAgent.toLowerCase();

    this.major = parseInt(navigator.appVersion);

    this.minor = parseFloat(navigator.appVersion);

     this.ns = ((agent.indexOf('mozilla') != -1) && 

          (agent.indexOf('spoofer') == -1) && (agent.indexOf('compatible') == -1) &&

         (agent.indexOf('opera') == -1) &&

         (agent.indexOf('webtv') == -1));    

    this.ns2   = (this.ns && (this.major      ==    3));

    this.ns3   = (this.ns && (this.major      ==    3));

    this.ns4   = (this.ns && (this.major      ==    4));

    this.ns6   = (this.ns && (this.major      >=    5));

    this.ie    = (agent.indexOf("msie")       !=   -1);

    this.ie3   = (this.ie && (this.major      < 4));

    this.ie4   = (this.ie && (this.major      ==    4) && (agent.indexOf("msie 5.0")   ==   -1));

    this.ie5   = (this.ie && (this.major      ==    4) && (agent.indexOf("msie 5.0")   !=   -1));

    this.ieX = (this.ie && !this.ie3 && !this.ie4); 

}



var is = new Is();



var url = 'http://www.publicentral.com';



</script>



</head>



<body onLoad="location.href = url;">



<H1>Page is loading...</H1>



<script type="text/javascript">

if (document.layers)

document.write('<layer src="' + url + '" visibility="hide"><\/layer>');



else if (document.all || document.getElementById)

document.write('<iframe src="' + url + '" style="visibility: hidden;"><\/iframe>');



else location.href = url;

</script>



</body>

</html>

Like stealth said, you should try putting the asp code in the frameset page.

you could always use a delay command for ASP. This will be set to delay the page for a specific amount of time....
You could even use a animated gif to show that the page is loading then go to a blank image in like 5 seconds or so.... then the page would load.

thats still hoping that the page executes last. all manor of things can go wrong

Just thinking out loud.....

Frame A:
Does what it has to do. When it's finished it adds a unique ID to a file/db
(maybe session ID)

Frame B:
Checks to see if it's session ID is in the file/database. If it's there, that means that Frame A is loaded and Frame B continues.. else it redirects to itself and checks again..and again..again...until the session ID is found in the DB

Issues (maybe) :
Infinate loops
Creating the unique ID
Will have to clean up the DB every so often

The people who pay me insist that I actually work for my money, so I don't have time to slap this one together.
