1、单页tab页切换注意事项
单页 tab 页切换：
拿到设计稿，本着能以 CSS 实现的效果不使用 JS 想法，我用了 radio 控制页面切换（实现子页切换、选择tab、为空提示）——OK。
考虑到页面交互体验（假设 A、B 子页）：A 滚动时，B 位置不受影响，做出修改：
方式1：
子页的父容器设置 height:100%，在这个条件下，滚动容器已经不是窗口自带的滚动了，表现为：
$(window).scroll(function() {
var scrollTop = $(document).scrollTop();
console.log(scrollTop);
});
页面滚动时，上述代码不打印。
如果是 ul.lst 实现的滚动，A、B 页滚动分别是各自 UL 容器, 注意有滚动条的容器要设置（overflow:auto，需要获取滚动距离[$(ele).offset().top]的还要设 position: relative)。
如果点击节点要跳转其他页面，再返回时，保持页面位置不变的话，可以在点击时获取滚动距离，通过 sessionStorage 记录位置，然后返回时获取并设置该滚动距离值。
缺点：
一式两份的感觉，啥代码都重复写，要有多个 tab 切换就脑壳疼了。
方式2：
利用 window 窗口滚动，点击 B 时，记录 A 的滚动距离[$(document).scrollTop()]，设置 B 的缓存距离；点击 A 时，记录 B 的滚动距离， 设置 A 的缓存距离。

2、使用 jq 创建，不要设置元素 id 名为 “nodeName”
3、单页切换刷新或跳转返回后不回到默认页。
4、文本内容多行时设置 word-break: all;

如图，红色字体标注和黄色横线标注是两种实现 CSS 展开关闭（radio）效果的方法。
对于红色的方法，是当图标大于指定数目再添加相应类 showMoreIcon 控制按钮展开图标容器高度。在 Android 环境下，浏览器或 APP 上正常操作。
而 iOS APP 环境下，foldBtn:checked ~ .showMoreIcon { max-height: 2.7rem } 没有效果了。我想原因是不是渲染顺序的问题，目前我所了解的是 js 加载完后才渲染 css ，这样这个写法没有问题的，这个写法在 Android APP 或 浏览器及 iOS 非APP环境下是可以的，而 OS APP 失败的原因是否是 css 同 HTML先渲染了，导致后面 js 动态添加类后 css 没有再次渲染导致的。
此外，点击详情再返回该页面就正常展开关闭了，
再后来……
换了黄色横线标注方法后，iOS APP 是正常了，安卓 APP 却出现 iOS 的情况，一顿操作后刷新或清缓存什么的，一切正常，我想苹果出现的问题是不是因为文件没有及时更新导致的。
