之前写过在 vue 中使用 mui 框架的方法，因为用 vue 开发后打包 5+App 会有一些问题，所以当时用到了，最近又一次开发移动端，不同的是这次使用的是 vue3 开发的，导致之前使用的 vue-awesome-mui 依赖不能使用了，因为作者很长时间没有维护了，vue3 不适用，后来了解到使用 plus 对象不需要 mui 的支持，是本身 html5+的对象，所以记录一下 plus 直接使用的方法
首先说一下，plus 在浏览器中是不起作用的，专门在 5+App 中使用的，主要作用是调用手机原生的一些功能。
以前认为 app 都是 java 写原生开发才是正宗的，挺早之前就用过 5+App 打包 app 应用，但始终觉得是一层覆盖到底层之上的，操作不了底层的功能，最近才终于真实的了解了 5+App。
各种操作方法，方法的说明、参数、回调、示例，可以查看html5plus 官方文档，里面都记录的很详细
值得一提的是plus.runtime.openURL(url, errorCB, identity)方法，这个可以用来唤醒其他的 app，这里的 url 的值可以是 UrlSchemes+“😕/”，UrlSchemes 就是在打包 app 时填写的 App 常用其他设置里的一项 Android 设置
下面就具体说一下
这里需要监听一下 plusready 事件，在这个成功的回调函数进行一些涉及到 plus 的操作，这个事件看字面意思就可以理解，plus ready就是 plus 准备好了的意思，这里我打印一下 plus 对象，因为打印在浏览器上无效，只能使用 HbuilderX 启动手机模拟器调试，所以需要使用JSON.stringify()格式化成字符串，否则在 HBuilderX 打印出来就是[Object Object]
document.addEventListener("plusready",function () {console.log(JSON.stringify(plus));},false);
打印出来的结果，我这里复制转回 JSON 格式的，里面有用的信息还是挺多的，但是这个只显示属性，不像浏览器的打印对象还给显示可操作的方法
