复制代码代码如下:

drag.js

Code kopieren Der Code lautet wie folgt:

(Funktion($){

    $.fn.drag360=function(images){

        var mdx,mmx,isDrag=false,unitStep=40,current=0;

        var that=$(this);

        var length=images.length;

        //触摸  

        that.on('touchstart',function(e){

            var touch = e.originalEvent;

                mdx = touch.changedTouches[0].pageX;

                isDrag=true;

        }).on('touchmove',function(e){

            e.preventDefault();

            touch = e.originalEvent.touches[0]||e.originalEvent.changedTouches[0];

            mmx=touch.pageX;

            if(isDrag){

                if(Math.abs(mmx-mdx)>unitStep){

                    if(mmx-mdx>0){

                        aktuell=aktuell 1; 

                    }else{

                        aktuell=aktuell-1;

                    }

                    mdx=mmx;

                    if(current<0)current=length-1;

                    if(current>length-1)current=0;

                    that.attr("src",images[current]);

                }

            }

        }).on('touchend',function(e){

            isDrag=false;

        });

        //拖动

        that.on('mousedown',function(e){

            mdx=e.pageX;

            isDrag=true;

        }).on('mousemove',function(e){

            mmx=e.pageX;

            if(isDrag){

                if(Math.abs(mmx-mdx)>unitStep){

                    current=current (mmx-mdx>0?1:-1);

                    mdx=mmx;

                    if(current<0)current=length-1;

                    if(current>length-1)current=0;
