处理:滑动页面事件、动画效果(缩放、各方位滑动、抖动、明暗)、

代码示例:  
**js文件:**

$(function(){ 
        //定义方向对象
        var direction={ up:1,right:2,down:3,left:4};
        //初始化两个页面坐标
        var now={ col:1,row:1};
        var last={ col:0,row:0};
    
        //上一个页面动画结束标志
        var isMoving=false;
    
        //定义滑动功能
        function movePage(dir)
        { 
            //初始化参与动画的页面,加'.'是因为可以之间获取dom对象
            var lastPage='.page-'+last.col+'-'+last.row;
            var nowPage='.page-'+now.col+'-'+now.row;
    
            //初始化动画类
            var inClass='';//进场动画类
            var outClass=''; //出场动画类
    
            //匹配方向
            switch(dir){ 
                case direction.up:
                    outClass='pg-moveToTop';
                    inClass='pg-moveFromBottom';
                    break;
                case direction.right:
                    outClass='pg-moveToRight';
                    inClass='pg-moveFromLeft';
                    break;
                case direction.down:
                    outClass='pg-moveToBottom';
                    inClass='pg-moveFromTop';
                    break;
                case direction.left:
                    outClass='pg-moveToLeft';
                    inClass='pg-moveFromRight';
                    break;
            }
            //之前页面退场
            $(lastPage).addClass(outClass);
            //当前页面进场
            $(nowPage).removeClass('hide');
            $(nowPage).addClass(inClass);
    
            isMoving=true;
    
    
            //动画执行完清除动画类,否则添加的重复类只执行一次
            //触发滑动事件后，等待600毫秒，即页面完全占据屏幕后，再执行动画
            //isMoving页面还未占据屏幕时，不能滑动
            //元素若设置了display:none;只有当元素显示的时候,动画才会执行，因此当600毫秒页面完全占据屏幕，才显示元素并加载动画
            setTimeout(function(){ 
                $(lastPage).removeClass(outClass);
                $(lastPage).addClass('hide');
