将代码放在主题的footer.php中的 < /body> 之前即可

    <script type="text/javascript"> 
    /* 鼠标特效 */
    var a_idx = 0; 
    jQuery(document).ready(function($) { 
        $("body").click(function(e) { 
            var a = new Array("富强", "民主", "文明", "和谐", "自由", "平等", "公正" ,"法治", "爱国", "敬业", "诚信", "友善"); 
            var $i = $("<span/>").text(a[a_idx]); 
            a_idx = (a_idx + 1) % a.length; 
            var x = e.pageX, 
            y = e.pageY; 
            $i.css({ 
                "z-index": 999999999999999999999999999999999999999999999999999999999999999999999, 
                "top": y - 20, 
                "left": x, 
                "position": "absolute", 
                "font-weight": "bold", 
                "color": "#ff6651" 
            }); 
            $("body").append($i); 
            $i.animate({ 
                "top": y - 180, 
                "opacity": 0 
            }, 
            1500, 
            function() { 
                $i.remove(); 
            }); 
        }); 
    }); 
    </script>

特效字体可以自行设置。其实WordPress博客也是一样的道理
