应用程序
我正在尝试创建一个简单的拍照应用，正在测试 phonegap 构建
当应用程序加载时，我得到一个控制台日志，上面写着 deviceready - 当设备准备就绪时记录
问题
当我点击按钮启动相机时，出现控制台错误:
未捕获的类型错误:无法读取未定义的属性“getPicture”
JS/HTML
<button onclick="app.takePicture();">Take Picture</button>
<script type="text/javascript" src="phonegap.js"></script>
<script>
var app = {
// Application Constructor
initialize: function() {
this.bindEvents();
},
// Bind Event Listeners
//
// Bind any events that are required on startup. Common events are:
// 'load', 'deviceready', 'offline', and 'online'.
bindEvents: function() {
document.addEventListener('deviceready', this.onDeviceReady, false);
},
// deviceready Event Handler
//
// The scope of 'this' is the event. In order to call the 'receivedEvent'
// function, we must explicity call 'app.receivedEvent(...);'
onDeviceReady: function() {
app.receivedEvent('deviceready');
},
// Update DOM on a Received Event
receivedEvent: function(id) {
var parentElement = document.getElementById(id);
var listeningElement = parentElement.querySelector('.listening');
var receivedElement = parentElement.querySelector('.received');
listeningElement.setAttribute('style', 'display:none;');
receivedElement.setAttribute('style', 'display:block;');
console.log('Received Event: ' + id); // <-- this works ok
},
takePicture: function() {
navigator.camera.getPicture( function( imageURI ) {
alert( imageURI );
},
function( message ) {
alert( message );
},
{
quality: 50,
destinationType: Camera.DestinationType.FILE_URI
});
}
};
app.initialize();
</script>
我也尝试过使用 cordova.js 但同样的问题。
我之前看到过这个问题，但找不到解决方法，有吗？有更好的方法吗？
最佳答案
想通了，虽然在任何地方都找不到这个记录!
确保将此添加到 config.xml 文件中:
<plugin name="org.apache.cordova.camera" spec="0.3.6" source="pgb" />
根据我的收集，这基本上创建了 navigator 对象
