 链接点击时的处理函数，第一个参数为链接数据对象。
 
+## 兼容性问题
+
+### Android UC
+
+**问题描述**：
+
+NavBar 两侧的链接（`.navbar-nav-item`）应用 `display: inline-flex` 以后，在部分只支持 09 版 flexbox 的规范的浏览器中宽度异常（有时比实际内容宽度宽一些，有时呈块级显示）。
+
+**测试环境**：
+
+- 设备：MI 4
+- 系统：Android 6.0.1 / MIUI 7 6.4.14 开发版
+- 浏览器：UCBrowser 10.9.8.738
+
+**解决方式**：
+
+由于 UC 浏览器在[特征检测中返回的数据不准确](https://codepen.io/anon/pen/WQLePg)，只能通过 UA 识别，然后作回退处理。
+
+```javascript
+var ua = navigator.userAgent;
+if (/android/i.test(ua) && /ucbrowser/i.test(ua)) {
+  document.documentElement.className += ' ua-android-uc';
+}
+```
+
+上面的 JS 需要开发者手动添加到自己的项目中（以下样式已经集成在 CSS 文件中，）。
+
+```css
+.ua-android-uc .navbar-nav-itme {
+  display: inline-block;
+}
+```
