Après avoir pris une photo à l'aide de phonegap (navigator.de la caméra.getPicture) comment puis-je stocker dans mon disque local?

Voici mon phonegap code. Ce code est fait pour prendre la photo ainsi que d'enregistrer l'image aussi:

<!DOCTYPE html>
<html>
<head>
<title>Capture Photo and Save</title>
<script type="text/javascript" charset="utf-8" src="cordova-2.5.0.js"></script>
<script type="text/javascript" charset="utf-8">
var pictureSource; //picture source
var destinationType; //sets the format of returned value 
//Wait for Cordova to connect with the device
document.addEventListener("deviceready", onDeviceReady, false);
//Cordova is ready to be used!
function onDeviceReady() {
pictureSource = navigator.camera.PictureSourceType;
destinationType = navigator.camera.DestinationType;
}
//Called when a photo is successfully retrieved
function onPhotoDataSuccess(imageData) {
//Uncomment to view the base64 encoded image data
var date = ""
var d = new Date();
date = "" + d.getDate() + "-" + (d.getMonth() + 1) + "-"
+ d.getFullYear();
alert(date)
//alert(imageData);  
//Get image handle
//
var smallImage = document.getElementById('smallImage');
//Unhide image elements
//
smallImage.style.display = 'block';
//Show the captured photo
//The inline CSS rules are used to resize the image
//
smallImage.src = "data:image/jpeg;base64," + imageData;
alert("data:image/jpeg;base64," + imageData)
//This part is for saving the capture photo
window.requestFileSystem(LocalFileSystem.PERSISTENT, 0, gotFS, fail);
function gotFS(fileSystem) {
alert("image/" + date + ".jpeg")
fileSystem.root.getFile("image/" + date + ".jpeg", {
create : true,
exclusive : false
}, gotFileEntry, fail);
}
function gotFileEntry(fileEntry) {
fileEntry.createWriter(gotFileWriter, fail);
}
function gotFileWriter(writer) {
var data = "data:image/jpeg;base64," + imageData;
writer.write(data);
}
function fail(error) {
alert("error")
console.log(error.code);
}
}
//Called when a photo is successfully retrieved
function onPhotoURISuccess(imageURI) {
//Uncomment to view the image file URI 
//console.log(imageURI);
//Get image handle
var largeImage = document.getElementById('largeImage');
//Unhide image elements
largeImage.style.display = 'block';
//Show the captured photo
//The inline CSS rules are used to resize the image
//
largeImage.src = imageURI;
}
//A button will call this function
function capturePhoto() {
//Take picture using device camera and retrieve image as base64-encoded string
navigator.camera.getPicture(onPhotoDataSuccess, onFail, {
quality : 50,
destinationType : destinationType.DATA_URL
});
}
//A button will call this function
//
function capturePhotoEdit() {
//Take picture using device camera, allow edit, and retrieve image as base64-encoded string  
navigator.camera.getPicture(onPhotoDataSuccess, onFail, {
quality : 20,
allowEdit : true,
destinationType : destinationType.DATA_URL
});
}
//A button will call this function
function getPhoto(source) {
//Retrieve image file location from specified source
navigator.camera.getPicture(onPhotoURISuccess, onFail, {
quality : 50,
destinationType : destinationType.FILE_URI,
sourceType : source
});
}
//Called if something bad happens.
function onFail(message) {
alert('Failed because: ' + message);
}
function savePhoto(source) {
}
</script>
</head>
<body>
<button onclick="capturePhoto();">Capture Photo</button>
<br>
<button onclick="capturePhotoEdit();">Capture Editable Photo</button>
<br>
<button onclick="savePhoto();">Save The Photo In Server</button>
<br>
<button onclick="getPhoto(pictureSource.PHOTOLIBRARY);">From
Photo Library</button>
<br>
<button onclick="getPhoto(pictureSource.SAVEDPHOTOALBUM);">From
PhotoAlbum</button>
<br>
<img style="display: none; width: 60px; height: 60px;" id="smallImage"
src="" />
<img style="display: none;" id="largeImage" src="" />
</body>
</html>

Je suis prise d'une photo et d'essayer de l'enregistrer comme ça, mais c'est sauvegarder dans un fichier non pas comme une image(binaire).donc, après l'enregistrement de l'image de son pas d'ouverture.Comment puis-je l'enregistrer avec une bonne obtenues afin que je puisse l'ouvrir en tant qu'image ?

    J'ai fait de cette façon:

    function capturePhoto() {
//Take picture using device camera and retrieve image as base64-encoded string
navigator.camera.getPicture(onPhotoDataSuccess, onFail, { quality: 50,
destinationType: Camera.DestinationType.FILE_URI, });
}
function onPhotoDataSuccess(imageURI) {
var gotFileEntry = function(fileEntry) {
//alert("got image file entry: " + fileEntry.fullPath);
var gotFileSystem = function(fileSystem) {
fileSystem.root.getDirectory("MyAppFolder", {
create : true
}, function(dataDir) {
var d = new Date();
var n = d.getTime();
//new file name
var newFileName = n + ".jpg";
console.log("Saved image" + dataDir);
//copy the file
fileEntry.moveTo(dataDir, newFileName, null, fsFail);
}, dirFail);
};
//get file system to copy or move image file to
window.requestFileSystem(LocalFileSystem.PERSISTENT, 0, gotFileSystem,
fsFail);
};
//resolve file system for image
window.resolveLocalFileSystemURI(imageURI, gotFileEntry, fsFail);
//file system fail
var fsFail = function(error) {
alert("failed with error code: " + error.code);
};
var dirFail = function(error) {
alert("Directory error code: " + error.code);
};
}

    Espère que cela vous aide!

    Si vous êtes ok pour enregistrer l'image dans la galerie de photos, puis essayer le code suivant : 

    function capturePhoto() {
//Take picture using device camera and retrieve image as base64-encoded string
navigator.camera.getPicture(onPhotoDataSuccess, onFail, { 
quality: 50,
destinationType : destinationType.FILE_URI,
saveToPhotoAlbum : true,
});
}

     function save(){
document.addEventListener("deviceready", onDeviceReady, false);
}
//PhoneGap is ready
//
function onDeviceReady() {
window.requestFileSystem(LocalFileSystem.PERSISTENT, 0, gotFS, fail);
}
function gotFS(fileSystem) {
fileSystem.root.getFile("pic.jpg", {create: true, exclusive: false}, gotFileEntry, fail);
}
function gotFileEntry(fileEntry) {
fileEntry.createWriter(gotFileWriter, fail);
}
function gotFileWriter(writer) {
var photo = document.getElementById("image");
writer.write(photo.value);
}
function fail(error) {
console.log(error.code);
}
    J'ai mis ces 2 lignes à l'intérieur de mon gotFileWriter fonction, mais j'ai eu une alerte Indéfini. var photos = document.getElementById("smallImage"); alert(photo.valeur);
    ce qui s'est vraiment passé bro
    mec, s'il vous plaît aller à travers mon code. je ne suis pas en mesure de stocker l'image.son économie comme un simple fichier.j'ai presque tout essayé, mais impossible de résoudre ce problème. besoin d'aide.
    bro, j'ai seulement de rechercher ce code pour l'u. je peux travailler beaucoup plus avec phonegap
