一.创建简单app应用
①
②
③连接手机
④
二.MUI 各组件的运用
http://dev.dcloud.net.cn/mui/snippet/
三. HTML5plus
参考文档: http://www.html5plus.org/
用来调用操作系统中的硬件驱动 + 系统调用
硬件驱动 - 摄像头 麦克风 闪光灯 扬声器 GPS 蓝牙 指纹 硬件
系统调用 - 通讯录 相册 文件管理 窗口管理 地图 短信 本地缓存
三方 - 三方登录 三方支付 三方推送
1.自定义代码块
mui.plusReady() 页面加载完成之后执行的的命令 (mpl)
①
②
③
四.事件
1.手势事件
①基本格式
②手势事件配置
mui.init({ gestureConfig:{ tap: true, //默认为true doubletap: true, //默认为false longtap: true, //默认为false swipe: true, //默认为true drag: true, //默认为true hold:false,//默认为false,不监听 release:false//默认为false,不监听 } });
③分类
2.自定义事件
①自定义事件窗口
②执行命令的窗口
五.窗口管理
1.打开新页面
//tap为mui封装的单击事件,可参考手势事件章节 document.getElementById('info').addEventListener('tap', function() { //打开关于页面 mui.openWindow({ url: 'examples/info.html', id:'info' }); });
打开新窗口
mui.openWindow({ url:"html.html", id:"html.html", extras:{name:1}, #传值 styles:{} #布局 })
2.页面之间传值 (webview)
①
②
3.创建子页面
(自动加载到主页面)
mui.init({ subpages:[{ url:your-subpage-url,//子页面HTML地址,支持本地地址和网络地址 id:your-subpage-id,//子页面标志 styles:{ top:subpage-top-position,//子页面顶部位置 bottom:subpage-bottom-position,//子页面底部位置 subpage-width,//子页面宽度,默认为100% height:subpage-height,//子页面高度,默认为100% ...... }, extras:{}//额外扩展参数 }] });
六.登录页面(前后端分离)
1.简单版
