Jquery图片分割轮换原理就是：将要显示的图片用多个Div显示，每个Div都以背景图片的方式加载图片，然后按照自己应该显示的区域来截取图片，最后拼接成一张完整的图片。

时间div{
            width:0px; height:100%; background-image:url(testImg.jpg); background-repeat:no-repeat;
            }
        " _ue_custom_node_="true">                                                 切换 div").css("background-image","url(testImg.jpg)");
                for (var i = 0; i div")[i]).css("width", "0px").css("height", "300px").css("background-position", ""   postionX   ",0px");
                    $($(".childDiv>div")[i]).animate({
                        width: "100px"
                    }, 500 (i*200));
                }
            } else {
                index = 0;
                $(".childDiv>div").css("background-image","url(testImg1.jpg)");
                for (var i = 0; i div")[i]).css("width", "100px").css("height", "0px").css("background-position", ""   postionX   ",0px");
                    $($(".childDiv>div")[i]).animate({
                        height: "300px"
                    }, 500 (i*200));
                }
            }
        }
