Check onload from IFrame

**guruk** · Feb 15, 2005 06:39

Hi,

i have a Page with a countdown timer and a IFrame.
In this Iframe i open, when the TImer is 0, a PHP Script that respond random Urls. So the result is like a diashow of different pages.

Now the Prob is, when the speed is slow the Iframe is not finished loaded the timer is 0 and starts to open another url.

How can i check if the IFrame is full loaded and after that I start my Timer to count?

Thanks chris

call a function on your main page from the iframe page

<body onload="parent.SetTimer();" >

if the iframe page is to be viewed ouside the IFRAME

function CheckParent(){

if (parent.location.match('MyPage.htm'){
parent.SetTimer();
}

}

Hi, thanks

but I can not put anything in the content of the iFrame. Because some of them are not mine. Thats the Prob.

I have to check from outside of this Iframe, in my parent WIndow if the content inside the IFrame is fully loaded and then I like to start my Counter. like:

(not working script for the Mainwindow, only for understanding, im not a js programmer)

If id.iframe.onload = true then startTimer.

I might suggest you use the onload attribute of the iframe's element tag to trigger your function. To place an event handler on the iframe element, you'll have to wait until the main page has finished loading, in order to apply it. That might cause timing problems.

Here's an example of that approach, just replace the alert('') with your function name:

Code:

  <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">
  <html>
  <head>
  <title>Untitled</title>
  <meta http-equiv="content-type" content="text/html; charset=iso-8859-1">
  </head>
  <body>
  <iframe id="ifOne" onload="alert('');" src="your_file_1.htm"></iframe>
  <a href="#" onclick="document.getElementById('ifOne').src='your_file_2.htm';">file</a>
  </body>
  </html>
