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); }, |
