Three JavaScript Questions…
#1
I have a frame index page with three frames. I would like the middle
frame (main) to present a random page each time a new visitor visits the page.
So far I have:
<html>
<head>
<meta name="GENERATOR" content="Microsoft FrontPage 5.0">
<meta name="ProgId" content="FrontPage.Editor.Document">
<meta http-equiv="Content-Type" content="text/html;
charset=windows-1252">
<title>New Page 1</title>
<script language="javascript" src="../../js/qxDelivery.js"> </script>
</head>
<body oncontextmenu="return false"
onload="javascript:chooseSurvey();">
</body>
</html>
// WINDOW DIMENSIONS //
function qxDisplay(url)
{
newwindow=window(url,'name','scrollbars=yes');
}
// SURVEY FUNCTION //
function chooseSurvey()
{
var aRandom_number = Math.random(); //Random Number Generation
if (aRandom_number <= 1.0) //Incident Rate = 100%
{
// INITIALIZE VARS
var survey = new Array(); // Survey is an array of
URLs
var number = 0;
// SET THE URLS
survey[number++] = "../content/surveys/cs-1.htm";
survey[number++] = "../content/surveys/cs-2.htm";
survey[number++] = "../content/surveys/cs-3.htm";
survey[number++] = "../content/surveys/isp-1.htm";
survey[number++] = "../content/surveys/isp-2.htm";
survey[number++] = "../content/surveys/isp-3.htm";
// RANDOMLY SELECT ONE OF THE ABOVE PAGE LOCATIONS
var increment = Math.floor(Math.random() * number);
// CALL THE POPUP WINDOW FUNCTION
qxDisplay(survey[increment]);
} // end if
// END FUNCTION
}
It doesn’t seem to work. Can anyone help?

I would like to prevent someone from hitting the “submit” button more
than once and thus double submitting the form. Can you provide a
simple JavaScript solution for this?
#3
I would like to initiate a timer that counts how long a person is on a
form from the time they answer the first question until the time they
hit submit. I would then like to send the resulting time as a hidden
variable to the form database. Can you provide a simple JavaScript
solution for this?
Thank you for your time,
