mounted下 获取元素距离顶部高度 + 状态栏高度

query.select('元素id').boundingClientRect(data => {
    this.topLocation = data.top + data.statusBarHeight;
}).exec();

获取滚动条距离

onPageScroll: function(Object) {
    this.currentScroll = Object.scrollTop;
},

滚动条距离 >= 元素距离顶部高度 的时候根据需求改变样式

这个判断在有刘海屏的iphone下就不准

这个是我少计算了什么元素的高度吗
