I wrote the following code. With this code pushing Submit button submits the form manually. I have also a timer which I want to auto submit the form after 10 seconds. But it does not work. It counts until 0 and then it does not do anything. Can you please tell me what I am missing or how to change my timer (if there, is the problem)? But I want the user to watch the timer as my example

Reset to default 3There are three errors producing this bug.
- You have a typo in form attributes. there is a space after
id. It should beid="myquiz". - Your form has a button named "submit", which is wrong. It overrides the function. Name it "submitbutton" or something other.
- The "validate" method is not defined. It should return true.
By the way, the timeout has wrong time, it should be 1000.
Working example: plunk
Don't do this:
var timer = setTimeout ('countDown('+secs+',"'+elem+'")',1500);
in countDown. Every 1500 you're calling countDown again.
Put this at the bottom of the page (before closing body tag)
<script type="text/javascript">
secs = 10;
timer = setInterval(function () {
var element = document.getElementById("status");
element.innerHTML = "<h2>You have <b>"+secs+"</b> seconds to answer the questions</h2>";
if(secs < 1){
clearInterval(timer);
document.getElementById('myquiz').submit();
}
secs--;
}, 1000)
Btw: where is validate() declared ?
Didn't test it, but it should do the trick.
You have to submit a form, not an element so try this:
document.forms["quiz"].submit();
OR if its the only form you can use
document.forms[0].submit();
This Code will work:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />
<script type="text/javascript">
function countDown(secs, elem)
{
var element = document.getElementById(elem);
element.innerHTML = "<h2>You have <b>"+secs+"</b> seconds to answer the questions</h2>";
if(secs < 1) {
document.quiz.submit();
}
else
{
secs--;
setTimeout('countDown('+secs+',"'+elem+'")',1500);
}
}
function validate() {
return true;
}
</script>
<div id="status"></div>
<script type="text/javascript">countDown(5,"status");</script>
<title>Questionnaire</title>
<style type="text/css">
span {
color: #FF00CC;
}
</style>
</head>
<body>
<h1>Please plete the following Survey</h1>
<form name="quiz" id="myquiz" onsubmit="return validate()" method="post" action="includes/process.php">
First Name: <input type="text" name="firstname" id="fname"/>
<p></p>
Last Name: <input type="text" name="lastname" id="lname"/>
<p></p>
<input type="submit" name="submitbutton" value="Go"></input>
<input type="reset" value="clear all"></input>
</form>
</body>
</html>
define function wait as
function caller()
{
setInterval(submit_now, 10000);
}
function submit_now()
{
document.forms["quiz"].submit();
}
Explaination:
1). Function wait() will set a time interval of 10 seconds (10000) ms before it calls submit_now() function.
2). On other hand submit_now() function do submit your form data when calling of this function is performed.
