js核心内容touch.js

function vueTouch(el,binding,type){//触屏函数
    var _this=this;
    this.obj=el;
    this.binding=binding;
    this.touchType=type;
    this.vueTouches={x:0,y:0};//触屏坐标
    this.vueMoves=true;
    this.vueLeave=true;
    this.vueCallBack=typeof(binding.value)=="object"?binding.value.fn:binding.value;
    this.obj.addEventListener("touchstart",function(e){
        _this.start(e);
    },false);
    this.obj.addEventListener("touchend",function(e){
        _this.end(e);
    },false);
    this.obj.addEventListener("touchmove",function(e){
        _this.move(e);
    },false);
};
vueTouch.prototype={
    start:function(e){//监听touchstart事件
        this.vueMoves=true;
        this.vueLeave=true;
        this.longTouch=true;
        this.vueTouches={x:e.changedTouches[0].pageX,y:e.changedTouches[0].pageY};
        this.time=setTimeout(function(){
            if(this.vueLeave&&this.vueMoves){
                this.touchType=="longtap"&&this.vueCallBack(this.binding.value,e);
                this.longTouch=false;
            };
        }.bind(this),1000);
    },
    end:function(e){//监听touchend事件
        var disX=e.changedTouches[0].pageX-this.vueTouches.x;//计算移动的位移差
        var disY=e.changedTouches[0].pageY-this.vueTouches.y;
        clearTimeout(this.time);
        if(Math.abs(disX)>10||Math.abs(disY)>100){//当横向位移大于10，纵向位移大于100，则判定为滑动事件
            this.touchType=="swipe"&&this.vueCallBack(this.binding.value,e);//若为滑动事件则返回
            if(Math.abs(disX)>Math.abs(disY)){//判断是横向滑动还是纵向滑动
                if(disX>10){
                    this.touchType=="swiperight"&&this.vueCallBack(this.binding.value,e);//右滑
                };
                if(disX<-10){
                    this.touchType=="swipeleft"&&this.vueCallBack(this.binding.value,e);//左滑
                };
            }else{
                if(disY>10){
                    this.touchType=="swipedown"&&this.vueCallBack(this.binding.value,e);//下滑
                };
                if(disY<-10){
                    this.touchType=="swipeup"&&this.vueCallBack(this.binding.value,e);//上滑
                };  
            };
        }else{
            if(this.longTouch&&this.vueMoves){
                this.touchType=="tap"&&this.vueCallBack(this.binding.value,e);
                this.vueLeave=false
            };
        };
    },
    move:function(e){//监听touchmove事件
        this.vueMoves=false;
    }
};
Vue.directive("tap",{//点击事件
    bind:function(el,binding){
        new vueTouch(el,binding,"tap");
    }
});
Vue.directive("swipe",{//滑动事件
    bind:function(el,binding){
        new vueTouch(el,binding,"swipe");
    }
});
Vue.directive("swipeleft",{//左滑事件
    bind:function(el,binding){
        new vueTouch(el,binding,"swipeleft");
    }
});
Vue.directive("swiperight",{//右滑事件
    bind:function(el,binding){
        new vueTouch(el,binding,"swiperight");
    }
});
Vue.directive("swipedown",{//下滑事件
    bind:function(el,binding){
        new vueTouch(el,binding,"swipedown");
    }
});
Vue.directive("swipeup",{//上滑事件
    bind:function(el,binding){
        new vueTouch(el,binding,"swipeup");
    }
});
Vue.directive("longtap",{//长按事件
    bind:function(el,binding){
        new vueTouch(el,binding,"longtap");
    }
});

将以上代码保存到一个js文件内，引入到页面vue库文件之后、用户js文件之前。这样就可以使用vue的触屏事件了。
