  outline: none;
  cursor: pointer;
  text-align: center;
  text-decoration: none;
  font: 16px/100% 'Microsoft yahei',Arial, Helvetica, sans-serif;
  padding: .5em 2em .55em;
  text-shadow: 0 1px 1px rgba(0,0,0,.3);
  -webkit-border-radius: .5em;

.orange {

  background: -webkit-gradient(linear, left top, left bottom, from(#faa51a), to(#f47a20));
  background: -moz-linear-gradient(top, #faa51a, #f47a20);
  filter: progid:DXImageTransform.Microsoft.gradient(startColorstr='#faa51a', endColorstr='#f47a20');
}
.orange:hover {
  background: #f47c20;
  background: -webkit-gradient(linear, left top, left bottom, from(#f88e11), to(#f06015));
  background: -moz-linear-gradient(top, #f88e11, #f06015);
  filter: progid:DXImageTransform.Microsoft.gradient(startColorstr='#f88e11', endColorstr='#f06015');
}
.orange:active {
  color: #fcd3a5;
  background: -webkit-gradient(linear, left top, left bottom, from(#f47a20), to(#faa51a));
  background: -moz-linear-gradient(top, #f47a20, #faa51a);
  filter: progid:DXImageTransform.Microsoft.gradient(startColorstr='#f47a20', endColorstr='#faa51a');
}

4、核心的JQuery代码:

<script>
//实现购物车+1动画效果
(function ($) {
  $.extend({
    tipsBox: function (options) {
      options = $.extend({
        obj: null, //jq对象,要在那个html标签上显示
        str: "+1", //字符串,要显示的内容
        startSize: "18px", //动画开始的文字大小
        endSize: "38px",  //动画结束的文字大小
        interval: 600, //动画时间间隔
        color: "red",  //文字颜色
        callback: function () { }  //回调函数
      }, options);
      $("body").append("<span class='num'>" + options.str + "</span>");
      var box = $(".num");
      var left = options.obj.offset().left + options.obj.width() / 2;
      var top = options.obj.offset().top - options.obj.height();
      box.css({
        "position": "absolute",
        "left": left + "px",
        "top": top + "px",
        "z-index": 9999,
        "font-size": options.startSize,
        "line-height": options.endSize,
        "color": options.color
      });
      box.animate({
        "font-size": options.endSize,
        "opacity": "0",
        "top": top - parseInt(options.endSize) + "px"
      }, options.interval, function () {
        box.remove();
        options.callback();
      });
    }
  });
})(jQuery);
function niceIn(prop){
  prop.find('i').addClass('niceIn');
  setTimeout(function(){
    prop.find('i').removeClass('niceIn');
  },1000);
}
//实现抛物线动画功能
$(function() {
  var offset = $("#end").offset();
  $(".addcar").click(function(event){
    var addcar = $(this);
    var img = "images/lg.jpg";
    var flyer = $('<img class="u-flyer" src="'+img+'">');
    flyer.fly({
      start: {
        left: event.pageX,
        top: event.pageY
      },
      end: {
        left: offset.left+10,
        top: offset.top+10,
        width: 0,
        height: 0
      },
      onEnd: function(){
        $.tipsBox({
            obj: $("#end"),
            str: "<b style='font-family:Microsoft YaHei;'>+1</b>",
            callback: function () {
            }
        });
        niceIn($("#end"));
      }
    });
  });
});
</script>
