var that=this;

that.animation.height(that.data.windowWidth * that.data.pixelRatio / 16 * 9 + 160).step()

that.setData({

animation: that.animation.export()

})

if (that.data.mapstatus == ‘bottom’){

that.setData({

mapstatus: ‘center’,

mapHeight: that.data.windowWidth * that.data.pixelRatio / 16 * 9 + 160

})

} else if (that.data.mapstatus == ‘center’){

that.setData({

status: ‘bottom’,

mapstatus: ‘top’,

mapHeight: that.windowHeight * 0.2

})

}

改变map 的高度，想有个动画效果 ,让map 下面的内容跟着 缩短和变长
