一个有意思的鼠标点击文字特效jquery代码

<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>
