Question

我正在尝试通过按钮让相机正常工作，但我在下面的注释行中遇到错误。我使用的是Phonegap / Cordova（v2.1）提供的文档。任何帮助表示赞赏。

    var pictureSource = navigator.Camera.PictureSourceType.CAMERA; // Cannot read PictureSourceType of undef
    var destinationType = navigator.camera.DestinationType.FILE_URI;

    function onPhotoURISuccess(imageURI) {
        var placeImage = document.getElementById('placeImage');
        placeImage.src = imageURI;
        placeImage.style.display = 'block';
        console.log(imageURI);
    }

    function getPhoto() {
        navigator.Camera.getPicture(onPhotoURISuccess, onFail, { //I am getting an error for this line saying camera is not defined?
             quality: 50, 
             destinationType: camera.destinationType.FILE_URI,
             sourceType: pictureSource
        });
    }

    function onFail(message) {
        alert('Failed because: ' + message);
    }

Answer 1

确保您首先获得“deviceready”活动。要调用getPicture（），请执行以下操作：

navigator.Camera.getPicture(onPhotoURISuccess, onFail, {
         quality: 50, 
         destinationType: navigator.camera.DestinationType.FILE_URI,
         sourceType: pictureSource
    });

Answer 2

我也正在研究这个问题。如果您在谈论Android，则需要在真实设备上进行测试。无论您在Eclipse中的浏览器或模拟器上进行测试，它都会为您提供Camera not defined error。我想这是因为硬件问题。

Camera和PictureSourceType未定义Phonegap
