Well,
the workflow is quite easy.
Store the time at the start of the survey.
In the last question take the time again, calculate the difference (in milliseconds) and if it is less than 10 minutes use
Code:
<script type="text/javascript" charset="utf-8">
$(document.ready(function(){
$('#ls-button-submit').hide();
setTimeout(function(){
$('#ls-button-submit').show();
},10000-difference);// value in milliseconds
});
</script>
to hide the submit button for the rest of time..
But why?
To avoid speeders? No problem, I click through the survey, then go to the kitchen, have a coffee, read the newspaper and then I submit the survey.
This is the first lesson a member of a panel learns.
I admit this can be useful if you want to display a text or an image for a certain time.
Better you have a look at the timing statistics.to find speeders.
