1. 点击时,点击处生成向上漂浮的小红心
<script type="text/javascript"> var a_idx=0; jQuery(document).ready(function($){$("body").click(function(e){ var a=new Array("❤","❤","❤","❤","❤","❤","❤","❤","❤","❤","❤","❤"); var $i=$("<span></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-20,"position":"absolute","font-weight":"bold","color":"#6699CC"}); $("body").append($i);$i.animate({"top":y-180,"opacity":0},1500,function(){$i.remove();}); });}); </script>
2.自动下雪.
<!--下雪 --> <script type="text/javascript"> (function ($) { $.fn.snow = function (options) { var $flake = $(\'<div id="flake"/>\').css({\'position\': \'absolute\', \'top\': \'-50px\'}).html(\'❄\'), documentHeight = $(document).height(), documentWidth = $(document).width(), defaults = {minSize: 10, maxSize: 20, newOn: 500, flakeColor: "#FF9900"}, options = $.extend({}, defaults, options); var interval = setInterval(function () { var startPositionLeft = Math.random() * documentWidth - 100, startOpacity = 0.5 + Math.random(), sizeFlake = options.minSize + Math.random() * options.maxSize, endPositionTop = documentHeight - 40, endPositionLeft = startPositionLeft - 100 + Math.random() * 200, durationFall = documentHeight * 10 + Math.random() * 5000; $flake.clone().appendTo(\'body\').css({ left: startPositionLeft, opacity: startOpacity, \'font-size\': sizeFlake, color: options.flakeColor }).animate({top: endPositionTop, left: endPositionLeft, opacity: 0.2}, durationFall, \'linear\', function () { $(this).remove() }); }, options.newOn); }; })(jQuery); $.fn.snow({minSize: 25, maxSize: 60, newOn: 1000, flakeColor: \'#CCCCCC\'}); </script>
