Hi,

Is there a way to set a counter to count a visit only if it lasts at least certain time (lets say at least 15 min)?

I'm making a library web page where we want to set up an e-books section - some of the books will probably be in .pdf format and some in html - I'm afraid timing for .pdf is not possible? But also books in .html format consist of many addresses - for example the cover is index.html, the contents page index2.html and the all contents index3.html - so counting one IP-s visit/time on page will be difficult...

Any ideas?


Best,
lemort

If you load the pdf and other pages in an iframe you may be able to make it work. The example below uses the onbeforeunload event as a trigger, but you could use a straight setTimeout for 15 minutes if that works better for you:


<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">
<html>
<head>
<title>Test</title>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
<script type="text/javascript">
var sTime=new Date();

window.onbeforeunload = function () {
var eTime=new Date();
alert ((eTime-sTime)/1000+ " seconds have elapsed");
}
</script>
</head>

<body>
<iframe src="file://path_to_File.pdf"></iframe>

</body>
</html>

hmm I guess I was misunderstood... or I get it wrong myself.

TheBearMay, this code shows the visitor how long s/he was on the page, but i need it for statistics - for myself. I need to know how many visitors stayed on the page (reading a book, and even better, if knowing which e-book) for more than 15 minutes.

I do have Google Analytics set for the home page, but this means a new tracking code for every existing e-book, as far as I understand, which is too much when having tens of books on page and it does not show visitors who watched a certain page (e-book) for n minutes; it only gives average time on page.

Oh, I understood you, just didn't want to get too bogged down in setting up an AJAX call to a server side back end if the concept didn't work for you.

Now when I actually think about, it might work.
I haven't found any counters that already do it :/

But is it able to leave me a log of visitors/visits (that have stayed for longer than 15 minutes) somewhere? I only know html, I have no experience in writing Ajax...

What do you have available on the back end language wise? Really just need something that can do a write to file or database on the server. Ajax wise something similar to the code below should work:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">
<html>
<head>
<title>Test</title>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">

<script type="text/javascript">
var httpObject = null;
var oDest = null;
function getHTTPObject(){
if (window.ActiveXObject) return new ActiveXObject("Microsoft.XMLHTTP");
else if (window.XMLHttpRequest) return new XMLHttpRequest();
else {
alert("Your browser does not support AJAX.");
return null;
}
}

function setOutput(){
if(httpObject.readyState == 4){
document.getElementById(oDest).innerHTML = httpObject.responseText;
}
}


function callAJAX(serverProc, odest){
oDest=odest;
/* readyState
* 0 = uninitialized
* 1 = loading
* 2 = loaded
* 3 = interactive
* 4 = complete
*/
httpObject = getHTTPObject();
if (httpObject != null) {
httpObject.open("GET", serverProc, true);
httpObject.send(null);
httpObject.onreadystatechange = setOutput;
}
}

setTimeout ("callAJAX('UpdateLog.php?ebook=path_to_File&ipAddr=255.255.255.0','oPut')",900000);

</script>
</head>

<body>
<iframe src="file://path_to_File.pdf"></iframe>
<div id="oPut"></div>

</body>
</html>

Need to add some logic around getting the IP address of course (Server Side Includes or a server side language).
