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>
