### uni-app Application Lifecycle 
### uni-app section of the page lifecycle 
### vue Lifecycle 
Contrast ### uni-app page life cycle and life cycle vue
###### page load load display → → → finished loading the page hide → page unload ###### uni-app page load onLoad: monitor page load → onShow: Listener page displays → onReady: listen first page rendering is complete → onHide: hidden listening page → onUnload: listener page unload ###### vue page load created: instance is created after execution → beforeMount: instance is executed → mounted before mounting: Mounting example after the completion of the implementation of → updated: execution after page → beforeDestroy updated: destruction before executing page
#### Based on the above comparison: Recommendations:
1、uni-app的页面生命周期仅在page页面有效，而单独封装的组件中【页面周期无效】，但是Vue的生命周期依然有效 【Vue的生命周期在任何地方都是有效的，即你仍然可以在uni-app项目中使用Vue生命周期，但是不建议这么做】
2、推荐使用uni-app里面的onLoad 代替 vue 里面的 created
3、推荐使用uni-app里面的onReady 代替 vue 里面的 mounted
