    function ShowRandom() {
        var $span = $(".random");
        var oldTop = 0;
        var oldLeft = 0;
        var leftPos = 10;
        var topPos = 10;

        $(".random").on("click", "#lion", function(event) {

        $span.fadeOut(500, function() {

            var maxLeft = $(window).width() - $span.width();
            var maxTop = $(window).height() - $span.height();

            oldTop = topPos;
            oldLeft = leftPos;

            leftPos = Math.floor(Math.random() * (maxLeft + 1));
            topPos = Math.floor(Math.random() * (maxTop + 1));          

            $span.css({ left: leftPos, top: topPos }).fadeIn(500);
        });
    };
    ShowRandom();
    setInterval(function(){         
        $('.random').append("<span class='lab'></span>");
        ShowRandom(); 
    }, 1500);
     $('.random').delegate('.lab', 'click', function() {
        $('.random').remove('.lab');
        alert('single event trigger');
    });


</script>
<style>
    span { 
        display: inline-block; 
        position: absolute;
    }
</style>
</head>
<body>
    <div id="container">
        <span class="random"><img src="lion.jpg" width="50px" height="50px" id="lion"></span>

    </div>
</body>
 </html>

I want only one alert box when I click on the image. But I get multiple alert boxes. Is there a way around it?

Thank You

    try moving 

    $(".random").on("click", "#lion", function(event) {
     alert(event.target.id);
});

    outside the ShowRandom function.

    ex:

    function ShowRandom(){...};

$(function(){

   $(".random").on("click", "#lion", function(event) {
         alert(event.target.id);
    }); 

    ShowRandom();

    setInterval(function(){
        $('.random').append("<span class='lab'></span>");
        ShowRandom(); 
    }, 1500);

    ...

});
