4、Camera 摄像头 | 系统相册操作 Gallery 


前言:这部分功能要在手机上才可见到效果,使用时注意手机连接。

1、H5+ 设备硬件信息操作

1)、device : 模块管理设备信息,用于获取手机设备的相关信息,如IMEIIMSI、型号、厂商等IMEI:设备的国际移动设备身份码;model:设备型号 ;拨打电话:dial(number,confirm) ;设备振动:vibrate(milliseconds ) ;保持唤醒(屏幕常亮)状态:setWakelock( lock )

2)、os管理操作系统信息 ;version: 系统版本信息 ;name: 系统的名称 。

3)、screen管理设备屏幕信息 ;设备屏幕分辨率:resolutionHeight | resolutionWidth ;锁定屏幕方向:lockOrientation 。

示例如下:

<!doctype html>
<html>

	<head>
		<meta charset="UTF-8">
		<title></title>
		<meta name="viewport" content="width=device-width,initial-scale=1,minimum-scale=1,maximum-scale=1,user-scalable=no" />
		<link href="css/mui.min.css" target="_blank" rel="external nofollow"  target="_blank" rel="external nofollow"  target="_blank" rel="external nofollow"  target="_blank" rel="external nofollow"  target="_blank" rel="external nofollow"  rel="stylesheet" />
	</head>

	<body>
		<script src="js/mui.min.js"></script>
		<script type="text/javascript">
			mui.init();
			
		</script>
		<header class="mui-bar mui-bar-nav">
		    <h1 class="mui-title">硬件基本信息</h1>
		   
		</header>
		<div class="mui-content">
		     <button type="button" class="mui-btn mui-btn-blue" id="btn1">获取设备信息</button>
		    <button type="button" class="mui-btn mui-btn-blue" id="btn2">振动</button>
		    <h4 id="dis"></h4>
		</div>
		<script type="text/javascript">
			mui.plusReady(function(){
				document.getElementById("btn1").addEventListener("tap",function(){				
					var str=plus.device.imei+"|"+
					plus.device.model+"|"+
					plus.os.name+"|"+
					plus.os.version+"|"+
					plus.screen.resolutionWidth+"|"+
					plus.screen.resolutionHeight;
					document.getElementById("dis").innerHTML=str;
					
				});
				document.getElementById("btn2").addEventListener("tap",function(){				
					plus.device.vibrate(1000);
					
				});
			});
			
		</script>
	</body>

</html>

 

2、Accelerometer 加速度仪

使用: plus.accelerometer获取设备加速度信息,包括x(屏幕水平方向)、y(垂直屏幕水平方向)、z(垂直屏幕平面方向)三个方向的加速度信息 ;getCurrentAcceleration: 获取当前设备的加速度信息 ,如 getCurrentAcceleration(successCB,errorCB) ;watchAcceleration: 监听设备加速度变化信息 :watchAcceleration(successCB,errorCB,option) ,option: {frequency:1000} ;clearWatch: 关闭监听设备加速度信息

示例:

<!doctype html>
<html>

	<head>
		<meta charset="UTF-8">
		<title></title>
		<meta name="viewport" content="width=device-width,initial-scale=1,minimum-scale=1,maximum-scale=1,user-scalable=no" />
		<link href="css/mui.min.css" target="_blank" rel="external nofollow"  target="_blank" rel="external nofollow"  target="_blank" rel="external nofollow"  target="_blank" rel="external nofollow"  target="_blank" rel="external nofollow"  rel="stylesheet" />
	</head>

	<body>
		<script src="js/mui.min.js"></script>
		<script type="text/javascript">
			mui.init()
		</script>
		<header class="mui-bar mui-bar-nav">
		    <h1 class="mui-title">加速度仪操作</h1>
		</header>
		<div class="mui-content">
		    <button type="button" class="mui-btn mui-btn-blue" id="btn1">获取加速度信息</button>
		    <button type="button" class="mui-btn mui-btn-blue" id="btn2">自动监听加速度信息</button>
		    <button type="button" class="mui-btn mui-btn-blue" id="btn3">停止监听</button>
		    <h4 id="dis"></h4>
		</div>
		<script type="text/javascript">
			mui.plusReady(function(){
				document.getElementById("btn1").addEventListener("tap",function(){				
					plus.accelerometer.getCurrentAcceleration(function(evt){
						var str=evt.xAxis+"|"+evt.yAxis+"|"+evt.zAxis;
						document.getElementById("dis").innerHTML=str;
					},
					function(e){
						alert("获取加速度信息失败!");
					});
					
				});
				var aID;
				document.getElementById("btn2").addEventListener("tap",function(){				
					//开始监听加速度
					aID=plus.accelerometer.watchAcceleration(function(evt){
						var str=evt.xAxis+"|"+evt.yAxis+"|"+evt.zAxis;
						document.getElementById("dis").innerHTML=str;
					},
					function(e){
						alert("获取加速度信息失败!");
					});
				});
				document.getElementById("btn3").addEventListener("tap",function(){
					plus.accelerometer.clearWatch(aID);  //停止监听						
				});
			});
		</script>
		
	</body>

</html>

 

3、条码扫描

barcode条码扫描:plus.barcode获取条码码管理对象,提供常见的条码(二维码及一维码)的扫描识别功能。

1)、扫描识别条码:

new plus.barcode.Barcode(‘容器ID’) ;onmarked:条码识别成功事件,回调函数参数:type,result,file ;start 、cancel setFlash

示例:

<!doctype html>
<html>

	<head>
		<meta charset="UTF-8">
		<title></title>
		<meta name="viewport" content="width=device-width,initial-scale=1,minimum-scale=1,maximum-scale=1,user-scalable=no" />
		<link href="css/mui.min.css" target="_blank" rel="external nofollow"  target="_blank" rel="external nofollow"  target="_blank" rel="external nofollow"  target="_blank" rel="external nofollow"  target="_blank" rel="external nofollow"  rel="stylesheet" />
	</head>

	<body>
		<script src="js/mui.min.js"></script>
		<script type="text/javascript">
			mui.init()
		</script>
		<header class="mui-bar mui-bar-nav">
		    <h1 class="mui-title">条码识别</h1>
		</header>
		<div class="mui-content">
		    <button type="button" class="mui-btn mui-btn-blue" id="btn">扫描</button>
		    <h4 id="dis"></h4>
		</div>
		<script type="text/javascript">
			document.getElementById("btn").addEventListener("tap",function(){
				mui.openWindow({
					url:"H5Demo3_sub.html",
					id:"H5Demo3_sub"
				});
			});
			window.addEventListener("barcode",function(evt){
				document.getElementById("dis").innerHTML=evt.detail.dt;
			});
		</script>
	</body>

</html>

2)、从图片中识别:

plus.barcode.scan(path,successCB,errorCB,filters ) 。

示例:

<!doctype html>
<html>

	<head>
		<meta charset="UTF-8">
		<title></title>
		<meta name="viewport" content="width=device-width,initial-scale=1,minimum-scale=1,maximum-scale=1,user-scalable=no" />
		<link href="css/mui.min.css" target="_blank" rel="external nofollow"  target="_blank" rel="external nofollow"  target="_blank" rel="external nofollow"  target="_blank" rel="external nofollow"  target="_blank" rel="external nofollow"  rel="stylesheet" />
		<style type="text/css">
			#bcd{
				height: 400px;
				background: rgb(30,30,30);
			}
			body{
				background: black;
			}
		</style>
	</head>

	<body>
		<script src="js/mui.min.js"></script>
		<script type="text/javascript">
			mui.init();
			mui.plusReady(function(){
				var barcode;
				var currW=plus.webview.currentWebview();
				var pW=currW.opener();
				currW.addEventListener("show",function(){
					barcode=new plus.barcode.Barcode("bcd");  //初始化扫描器对象
					barcode.onmarked=function(type,result){  //条码识别成功事件
//						alert(result);
						mui.fire(pW,"barcode",{dt:result});
						mui.back();
					};
					
					barcode.start();
				});
				
				
			});
		</script>
		<header class="mui-bar mui-bar-nav" style="background: black;">
		    <a class="mui-action-back mui-icon mui-icon-left-nav mui-pull-left"></a>
		    <h1 class="mui-title" style="color: white;">扫描器</h1>
		</header>
		<div class="mui-content">
		    <div id="bcd"></div>
		</div>
		<div class="mui-bar mui-bar-footer" >
			<span class="mui-icon mui-icon-flag mui-pull-right"></span>			
		</div>
	</body>

</html>

 

4、Camera 摄像头 | 系统相册操作 Gallery 

1)、Camera摄像头操作:用于拍照、摄像操作。plus.camera获取摄像头管理对象 ;getCamera(index) : 获取摄像头管理对象,包括 1:主摄像头,2:辅助摄像头 ;captureImage(successCB,errorCB, CameraOption) ;successCB=function(path){} ,path指照片保存位置 。

2)、图片显示问题 :img 的 src 必须经过路径转换 plus.io.resolveLocalFileSystemURL

3)、保存到系统相册 :plus.gallery.save(path,function(){})

4)、从系统相册中选择图片 :plus.gallery.pick(function(path){})

示例:

<!doctype html>
<html>

	<head>
		<meta charset="UTF-8">
		<title></title>
		<meta name="viewport" content="width=device-width,initial-scale=1,minimum-scale=1,maximum-scale=1,user-scalable=no" />
		<link href="css/mui.min.css" target="_blank" rel="external nofollow"  target="_blank" rel="external nofollow"  target="_blank" rel="external nofollow"  target="_blank" rel="external nofollow"  target="_blank" rel="external nofollow"  rel="stylesheet" />
	</head>

	<body>
		<script src="js/mui.min.js"></script>
		<script type="text/javascript">
			mui.init()
		</script>
		<header class="mui-bar mui-bar-nav">
		    <h1 class="mui-title">相机</h1>

		    <button type="button" class="mui-btn mui-btn-blue" id="btn3">读取系统相册中的照片</button>
		    <img id="dis" width="100%"></img>
		</div>
		<script type="text/javascript">
			mui.plusReady(function(){
				document.getElementById("btn").addEventListener("tap",function(){
					var camera=plus.camera.getCamera();
					camera.captureImage(function(evt){
						alert(evt);
						var path=plus.io.convertLocalFileSystemURL(evt);  //转换路径
						document.getElementById("dis").src=path;
					},
					function(){
						alert("拍照失败!");
					});
				});
				document.getElementById("btn2").addEventListener("tap",function(){
					
					plus.gallery.save(document.getElementById("dis").src,
					function(){
						alert("OK");
					},function(){
						alert("err");
					}
					);
				});
				document.getElementById("btn3").addEventListener("tap",function(){
					
					plus.gallery.pick(function(path){
						document.getElementById("dis").src=path;
					},function(){
						alert("读取图片失败!");
					});
				});
			});
