jquery - slideshow buttons function

I have here a slideshow: fiddle
Codes: CSS:

#slideshow {
    margin: 50px auto;
    position: relative;
    width: 240px;
    height: 240px;
    padding: 10px;
    box-shadow: 0 0 20px rgba(0, 0, 0, 0.4);
}
#slideshow > div {
    position: absolute;
    top: 10px;
    left: 10px;
    right: 10px;
    bottom: 10px;
}

#slideshow img {
    max-width:240px;
    max-height:240px;
}

ul {
    list-style:none;
    margin:0px;
    padding:0px;
}
ul li {
    float:left;
    border-radius:10px;
    width:10px;
    height:10px;
    border:1px solid white;
    background:grey;
}
ul li.active {
    background:black;
}

HTML:

<div id="slideshow">
    <div>
        <img src="http://farm6.static.flickr.com/5224/5658667829_2bb7d42a9c_m.jpg" />
    </div>
    <div>
        <img src="http://farm6.static.flickr.com/5230/5638093881_a791e4f819_m.jpg" />
    </div>
    <div>
        <img src="http://gillespaquette.ca/images/stack-icon.png" />
    </div>
</div>
<ul></ul>

Jquery:

$("#slideshow > div:gt(0)").hide();

var maxindex = $('#slideshow > div').length;

var index = 0
var interval = 3 * 1000; // 3 seconds
var timerJob = setInterval(traverseSlideShow, interval);

function traverseSlideShow() {
    console.log("current index: " + index);

    $('#slideshow > div')
        .stop()
        .fadeOut(1000);
    $('#slideshow > div').eq(index)
        .stop()
        .fadeIn(1000);

    $('ul li').removeClass('active');
    $('ul li:eq(' + index + ')').addClass('active');
    index = (index < maxindex - 1) ? index + 1 : 0;

}

for (var i = 0; i < maxindex; i++) {
    $('ul').append('<li class="' + (i == 0 ? 'active' : '') + '"></li>');
}

$(document).on('click', 'ul li', function () {
    index = $(this).index();
    traverseSlideShow();
    clearInterval(timerJob);
    timerJob = setInterval(traverseSlideShow, interval);
});

As you can see in the slideshow, when you click one of the buttons (enter image description here) the slideshow goes to a photo that the button you clicked is related with.
What I'm trying to do is very simple, the function accept 1 request every 1 second at maximum so user can not spam-click on the buttons, that means the function should break 1 second with every click and prevent loading a different image for different button through this 1 second(in this 1 second the slideshow should load the photo requested).
I'm trying to make my question more clear, lets say we have the three buttons 1, 2, 3 click on button 1 the function takes 1 second to load the photo(through that 1 second if you click the button 2 or 3 the function doesn't load the photo for 2 or 3), and so on.

You can use that jQuery as: $("#attrid").attr("disabled", true);
This will set an attribute to that button as disabled. Then you can use this JavaScript!
setInterVal(function(), timeInSeconds);
And from this again you can remove the disabled attribute from that!

Try a simple flag based workaround like

var timerFlag = false; // a flag to keep track of the click state
$(document).on('click', 'ul li', function () {
    if(timerFlag){// if the click state is true within last 1 sec there was a click so don't do anything
        return
    }

    index = $(this).index();
    traverseSlideShow();
    clearInterval(timerJob);
    timerJob = setInterval(traverseSlideShow, interval);

    setTimeout(function(){ //after a second set the flag to false
        timerFlag = false;
    }, 1000);
    timerFlag = true;// set the click flag to true
});

Demo: Fiddle
