就是像美团外卖一样，点击物品飞入购物车，不管点击“+”哪里那个红点都是从同一个位置飞入购物车

//点击点的坐标

this.finger['x'] = e.touches["0"].clientX;

this.finger['y'] = e.touches["0"].clientY;

//动画

startAnimation: function() {

var index = 0,

that = this,

bezier_points = that.linePos['bezier_points'];

this.setData({

hide_good_box: false,

bus_x: that.finger['x'],

bus_y: that.finger['y']

})

index = bezier_points.length;

this.timer = setInterval(function() {

index--;

that.setData({

bus_x: bezier_points[index]['x'],

bus_y: bezier_points[index]['y']

})

if (index<1) {

clearInterval(that.timer);

// that.addGoodToCartFn();

that.setData({

hide_good_box: true

})

}

}, 20);

},
