/* author:zhaoyulong 本次封装触屏事件实现触屏操作更加细腻 调用方式: $(xxx).touchme(event,function(distance,type,axis){ //distance:代表x轴或者y轴偏移(以偏移更多的一个方向为准) 可为正值或负值,代表不同方向的偏移 //type:为move时表示当前触发的是touchmove事件,为click时触发的是touchend事件 //axis:为x代表x轴偏移,为y代表y轴偏移 }); */ $.fn.touchme = function(event,fn){ var startele = $(this); var touch = event.targetTouches[0]; var endPos = false; startPos = {x:touch.pageX,y:touch.pageY,time:+new Date}; isScrolling = 0; startele.bind("touchmove",function(event){ if(event.targetTouches.length > 1 || event.scale && event.scale !== 1) return; var touch = event.targetTouches[0]; endPos = {x:touch.pageX - startPos.x,y:touch.pageY - startPos.y}; isScrolling = Math.abs(endPos.x) < Math.abs(endPos.y) ? 1:0; if(isScrolling === 0){ event.preventDefault(); fn(endPos.x,'move','x'); }else{ event.preventDefault(); fn(endPos.y,'move','y'); } }); startele.bind("touchend",function(event){ var duration = +new Date - startPos.time; if(isScrolling === 0){ fn(endPos.x,'click','x'); }else{ fn(endPos.y,'click','y'); } startele.unbind("touchmove"); startele.unbind("touchend"); }); };
