Make decisions based on content of a iframe?

Hello Expert,
I've got a Mobotix web cam and I would like to make a decision in a web site based on the default resolution the web cam is using. If you send a specific parameter to the cam it will tell you what resolution it is using.
The URL/parameter is:

http://192.168.1.10/control/control?read§ion=imagecontrol&size

 I think of doing this in a iframe but can't think of a way how to catch the output.

It's response will be a htm site with only this content:
Size=640x480
Or
Size=800x600

Question:

Can I based on the response make decisions in a JavaScript or ASP?
I have this script:

<script language="Javascript">
function linkr(IP){
  document.frames["iframeA"].location.href = "http://" + IP + "/control/control?set&section=general&size=800x600"
  document.frames["iframeB"].location.href = "http://" + IP + "/control/rcontrol?action=ledsdefault"
}
</script>

Now this script tells the cam to go to size 800X600 and turn its leds to default (on).
This is the case if the response would be Size=640x480 But if the response would be Size=800x600 the script should be:


<script language="Javascript">
function linkr(IP){
  document.frames["iframeA"].location.href = "http://" + IP + "/control/control?set&section=general&size=640x680"
  document.frames["iframeB"].location.href = "http://" + IP + "/control/rcontrol?action=ledsoff"
}
</script>

Thanks,

Steynsk

just read frame  .innerHTML (after loading it.. so first attach onload event).  -> is that what you want?

Hi wilq32:,

Yes I'll attach the complete code of both files involved. In screen touch.htm I show 12 mini screens of 12 cams in Iframe's. The mini screens are presented by view.asp and have a body onclick event. That triggers the javascript in de parent file. En in this version it is only possible to switch the cams on. But I would like to make is possible to switch them back again. But for this you need t detect the status of the cam.
And this can be done with:

http://192.168.1.10/control/control?read&section=imagecontrol&size

My Idea is create one more hidden Iframe with the URL/command in it and catch the result from the cam.
And based on that value trigger the right command in the javascript.

My knowlige of javascript little but I understand how things work.

So your help is very much appreciated,

Steynsk

I just wonder do you know that you paste local IP adress of this site, but I assume that its only for showing link type..

What i propose in previous post, just a little more explanation:

make <iframe id="someFrame"> element

then in that frame open your page:

document.getElementById('someFrame').src='http://192.168.1.10/control/control?read§ion=imagecontrol&size';


on that page make javascript that will run function from your main script.

Script in main window:

function checkIframe()
{
alert(document.getElementById('someFrame').innerHTML)

}


and in this small iframe page:

<script type="text/javascript">
function start()
{
     window.parent.checkIframe();
}
</script>

<body onload="start()">
content here
</body>




Is that a little more clear to you ?:)

Hi wilq32:
The IP in the code is only an example.

Yes that is about it . But I don't know how to implement it into my code. And I (think) I mis the decision making part in my script based on the catched value.

The value catched by :

document.getElementById('someFrame').innerHTML)

should be used to determen the value of the bold text parts in this script:

<script language="Javascript">
function linkr(IP){
  document.frames["iframeA"].location.href = "http://" + IP + "/control/control?set&section=general&size=800x600"
  document.frames["iframeB"].location.href = "http://" + IP + "/control/rcontrol?action=ledsdefault"
}
</script>
The catched value "Size=800x600" should result in the script in de values "640x480" and "ledsoff"
 The catched value "Size=640x480" should result in the script in de values "800x600" and "ledsdefault"
Thanks,
Steynsk

ok instead of:
function checkIframe()
{
alert(document.getElementById('someFrame').innerHTML)

}

just do:

function checkIframe()
{
  var set;

  if (document.getElementById('someFrame').innerHTML.match('Size=800x600'))
      set=["800x600", "ledsdefault"];
  if (document.getElementById('someFrame').innerHTML.match('Size=640x480'))
      set=["640x480", "ledsoff"];
 
 document.frames["iframeA"].location.href = "http://" + IP + "/control/control?set&section=general&size="+set[0];
 document.frames["iframeB"].location.href = "http://" + IP + "/control/rcontrol?action="+set[1];
}

Sorry I did use

<body bgcolor=black onclick="parent.linkr('<% response.write IP %>');"
But that did not solve the problem.

Pawel WitkowskiSenior Javascript DeveloperCommented:
just add alert (IP) at the begining of function, and check is function takes proper argument, then you have to check is this function being started from test script, and make sure that you opened this test script - because it opens this function

Wilq32,

The command alert(IP) return the IP as expected. While the command:
alert(document.getElementById('iframeA').innerHTML)
Does not return a value but an empty msbox.

Do you have any ideas?

Kind regards,

It looks like the site being read before it has content. How do I add a sleep before reading it?

Adding

setTimeout("alert(document.getElementById('iframeA').innerHTML)",5000);

Does result in the Iframe prsenting the wanted information but the alert not showing it...

Pawel WitkowskiSenior Javascript DeveloperCommented:
Hmmm thats odd. Lets check everything from begining. Check that onload on "checking" (that will return Size=800x600) page work. It should fire window.parent.checkIframe() so a function from parent window. Put an alert at the begining of checkIframe in main window and see is it fired after opening "checking" page in frame. If yes then check one most important thing. If your "checking" page is on other domain that your main page - it will not work, because of security polices that prevent reading from contentDocument.body. So if you main page is:

localhost/main.html

and your checking is

someadress.net/check.html

Then it wont work. You have to make sure that its on one server - if not you have two choices:
- server side: open the page from server side and depending on its content put needed information,
- client side: use dynamic javascript includes (require that you have access to "checking" page)

wilq32,

Yes you probably right. The script could possibly not detect it ha to read a page on the same domain becouse the webserver is a domain member and the web cam that has to produce the output is not.

In the meaintime I've found out that ASP can solve my problem. I include the code.
But this code has odd things aswel becouse it produces output but I cant work with it....

the code beneith is producing the output:

size=640x480 False

and it should produce

size=640x480 True

Do you have a ideas what could couse this?

Yes you are right. But does not matter.

But I found this script and it does the job. I don't know exactly what solves it but I can go on.

Thanks a lot for all your help.

    set xmlhttp = CreateObject("MSXML2.ServerXMLHTTP")  
    on error resume next 
    xmlhttp.open "GET", url, false 
    xmlhttp.send ""  
        if instr(xmlhttp.responseText,"640x480")>0 then 
            response.write "It works" 
        else 
            response.write "No luck" 
        end if
