html代码：

<div style="width: 300px;height: 300px;background-color: red" id="app" class="box" v-tap="vuetouch"
v-longtap="{fn:vuetouch,name:'长按'}"

v-swipeup="{fn:vuetouch,name:'上滑'}"
v-swipedown="{fn:vuetouch,name:'下滑'}">
    {{ name }}
</div>

js代码：

<script src="vue.js"></script><!--vue.js-->
<script src="touch.js"></script><!--核心手指滑动js-->
<script>
    kim=new Vue({
        el:"#app",
        data:{
            name:"开始"
        },
        methods:{
            vuetouch:function(s,e){
                this.name 

=s.name 

;
            }
        }
    });
</script>

手指滑动touch.js代码：

    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);
};
