Question

My client needs to prove that someone spent a certain amount of time on a page of their WordPress site. Do you know of a way that we could have a page that would have a timer on it that they couldn’t click on the next button until the timer hit the right number of minutes? Can any one suggest any plugins or methods to achieve it.

Answer 1

For a pure client side solution I would suggest a javascript plugin that

1. Disables all buttons on page load
2. Sets a timeout
3. Enable all buttons on timeout

In JQuery it would look something like this

$(document).ready(function(){
   $('input[type=button],button').attr('disabled','disabled');
   setTimeout(function () { $('input[type=button],button').removeAttr('disabled'); }, 5000);
});

Note: Users with javascript disabled won’t have this functionality
