I have a condition if my parent div has children with class .ads then it should alert('true') else alert('false'). But my function returns true in both cases. Here is jsFiddle link http://jsfiddle.net/F3EXf/

<head>
    <script type="text/javascript" src="jquery-1.7.2.js"></script>
    <script type="text/javascript">
        $(function(){
            if($('#me').find('.ads')){
                alert('true')
            } else {
                alert('false')
            }
        });
    </script>
</head>
<body>
    <div id="me">
        <div class="noads">aaaa</div>
    </div>
</body>

    To check if an element exists use instead

    if ($('#me').find('.ads').length) {
   ...
}

    Since $('#me').find('.ads') will always return true (it returns a jQuery-wrapped empty object evaluated as a true value) even if the element targeted by find() doesn’t exist
