Question

我正在尝试拍摄照片并访问照片库，因为我的控制台没有显示任何错误，所以我不知道如何使其工作。我正在使用Phonegap，jquery和jquery mobile。

这是我的HTML

<div data-role="content">
<button onclick="capturePhoto();">Capture Photo</button> <br>
<button onclick="capturePhotoEdit();">Capture Editable Photo</button> <br>
<button onclick="getPhoto(pictureSource.PHOTOLIBRARY);">From Photo Library</button><br>
<button onclick="getPhoto(pictureSource.SAVEDPHOTOALBUM);">From Photo Album</button><br>
<img style="display:none;width:60px;height:60px;" id="smallImage" src="" />
<img style="display:none;" id="largeImage" src="" />
</div>

和我的JS

var pictureSource;   
var destinationType;  

//
document.addEventListener("deviceready",onDeviceReady,false);
//
function onDeviceReady() {
    pictureSource=navigator.camera.PictureSourceType;
    destinationType=navigator.camera.DestinationType;
}

//
function onPhotoDataSuccess(imageData) {
  //
  var smallImage = document.getElementById('smallImage');

  smallImage.style.display = 'block';

  //
  smallImage.src = "data:image/jpeg;base64," + imageData;
}

function onPhotoURISuccess(imageURI) {

  var largeImage = document.getElementById('largeImage');
  largeImage.style.display = 'block';
  largeImage.src = imageURI;
}

function capturePhoto() {
  navigator.camera.getPicture(onPhotoDataSuccess, onFail, { quality: 50,
    destinationType: destinationType.DATA_URL });
}
function capturePhotoEdit() {
  navigator.camera.getPicture(onPhotoDataSuccess, onFail, { quality: 20, allowEdit: true,
    destinationType: destinationType.DATA_URL });
}

function getPhoto(source) {
  navigator.camera.getPicture(onPhotoURISuccess, onFail, { quality: 50, 
    destinationType: destinationType.FILE_URI,
    sourceType: source });
}
function onFail(message) {
  alert('Failed because: ' + message);
}

如果您正在编写Android应用程序并且想要使用手机中的硬件，则必须在AndroidManifest.xml文件中实现该应用程序的权限：这些是一些权利：

<uses-permission android:name="android.permission.CAMERA" />

将它粘贴到AndroidManifest.xml文件中：

<application>

通常你可以在网上找到所有权限，尝试搜索官方的手机短信书。
