Your problem

Using $('#countdown').html() will return all the HTML within the #countdown element. If your own version is anything like the demo you've linked to, this will return:

<span class="countDays"><span class="position">                 <span class="digit static" style="top: 0px; opacity: 1;">0</span>               </span>             <span class="position">                 <span class="digit static" style="top: 0px; opacity: 1;">0</span>               </span></span><span class="countDiv countDiv0"></span><span class="countHours"><span class="position">                  <span class="digit static" style="top: 0px; opacity: 1;">0</span>               </span>             <span class="position">                 <span class="digit static" style="top: 0px; opacity: 1;">0</span>               </span></span><span class="countDiv countDiv1"></span><span class="countMinutes"><span class="position">                    <span class="digit static" style="top: 0px; opacity: 1;">0</span>               </span>             <span class="position">                 <span class="digit static" style="top: 0px; opacity: 1;">0</span>               </span></span><span class="countDiv countDiv2"></span><span class="countSeconds"><span class="position">                    <span class="digit static" style="top: 0px; opacity: 1;">1</span>               </span>             <span class="position">                 <span class="digit static" style="top: 0px; opacity: 1;">7</span>               </span></span>

Pulling the numbers

If you want to return the numbers, you can instead pull the text(). This will initially give you:

" 0 0 0 0 0 2 1 2 "

We can then call replace() to remove those spaces and return a string like:

$('#countdown').text().replace(/\s+/g, '');
-> "00000212"

We can then use this instead:

var mytime = $('#countdown').text().replace(/\s+/g, '');
if (mytime == "00010540")
    ...

Checking periodically

The further problem with your code is that you only run that check once. As the #countdown element changes every second, we can add a timer which checks this value every second:

setInterval(function() {
    // Your function here
    var mytime = $('#countdown').text().replace(/\s+/g, '');
    if (mytime == "00010540")
        ...
}, 1000);

Here, 1000 is 1000 milliseconds, which is equal to 1 second.
