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>
