//js逻辑

nextID = 0; 


var setIntervalID,


setIntervalTime = 3000,


speed = 500;




//设置 图片容器 的宽度

$(imageBox).css({


'width': imageRollWidth + "px"


});


//图片切换函数

function imageRoll(clickID) {


if (clickID) {


nextID = clickID;


} else {



if (activeID <= 5) {




nextID = activeID + 1



} else {

}


}



//图标添加样式、删除样式


$(iconArr[activeID - 1]).removeClass("active");


$(iconArr[nextID - 1]).addClass("active");



$(imageBox).animate({

}


setIntervalID = setInterval(imageRoll, setIntervalTime);


//鼠标移动事件

//鼠标点击事件


$(iconArr).click(function() {



clearInterval(setIntervalID);



var clickID = parseInt($(this).attr("rel")); //获取当前点击图片的id



imageRoll(clickID);



setIntervalID = setInterval(imageRoll, setIntervalTime);



});

　});
});
