<script type="text/javascript" charset="utf-8"> 



var pictureSource; // Picture source

// PhoneGap is ready to be used! 

function onDeviceReady() 

{ 


    pictureSource = navigator.camera.PictureSourceType;

} 

function capturePhoto() { 

    navigator.camera.getPicture(onPhotoURISuccess, onFail, { quality: 25, destinationType:

function onPhotoURISuccess(imageURI) { 

    createFileEntry(imageURI); 
} 

function createFileEntry(imageURI) {

    console.log(entry.fullPath)

function fail(error) {

Answer 1

您應該使用PhoneGap 2.0.0 camera object。該文檔提供了一個完整的照片捕獲示例。

此外，navigator.camera.getPicture(cameraSuccess, cameraError, [ cameraOptions ]);使用相機拍攝照片或從設備相冊中檢索照片。該圖像作爲base64編碼的字符串返回或作爲圖像文件的URI返回。

我希望這會有所幫助。
