Prevent page scroll after click?

Question

After clicking on the link, Click Me, the page scrolls back to the top. I do not want this. How can fix it?

Example: http://jsfiddle.net/Y6Y3Z/

Scroll-bar:

    function myalert() {
        var result = true;
        //var hide = $('.alert').fadeOut(100);
        //var css = $('#appriseOverlay').css('display','none');
        var $alertDiv = $('<div class="alert">Are you sure you want to delete this item?<div class="clear"></div><button class="ok">no</button><button class="cancel">yes</button></div>');
        var link = this;
        $('body').append($alertDiv);
        $('.ok').click(function () {
            $('.alert').fadeOut(100);
            $('#appriseOverlay').css('display', 'none');
            callback(true, link);
        });
        $('.cancel').click(function () {
            $('.alert').fadeOut(100);
            $('#appriseOverlay').css('display', 'none');
            callback(false, link);
        });
        $alertDiv.fadeIn(100);
        $('#appriseOverlay').css('display', 'block');
        return result;
    };
$('.click').click(myalert);
    function callback(result, link) {
        //
        if(result){
        }
    }

You only need to change the "#" to "javascript:void(0)" on HTML code:

<a href="javascript:void(0)" class="click">Click Me</a>

Another solution is add a "/" after the "#":

<a href="#/" class="click">Click Me</a>
