如何在PhoneGap的移动拍摄的图像在SD卡的文件夹 [英] How to move captured image in PhoneGap to a folder in sdcard
本文介绍了如何在PhoneGap的移动拍摄的图像在SD卡的文件夹的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我使用以下code要获得图片的base64数据可显示并上传到服务器。
但我想在保存文件夹中的SD卡这个拍摄的图像。请帮我做到这一点。
这是必要的，我得到的base64图像数据，因为服务器只支持这种格式。这就是为什么我使用destinationType = 0（表示DATA_URL）。我现在的base64有图像数据，但我怎么能保存这些数据到SD卡？
uploadPhoto（isSourceCamera，onPhotoDataSuccess，onFail）;功能uploadPhoto（isSourceCamera，onPhotoDataSuccess，onFail）
{
pictureSource = navigator.camera.PictureSourceType;
如果（isSourceCamera）
{
//质量一定要低，以避免内存问题ON IPHONE4！ （和其他低内存的手机）。
//必须调整，使之更快地上传和避免与低内存的手机的失败。
navigator.camera.getPicture（onSuccessFunc，onFail，{
品质：35，
sourceType的：pictureSource.CAMERA，
targetWidth：750，
targetHeight：750，
allowEdit：真实，
destinationType：0
}）;
}

navigator.camera.getPicture（onSuccessFunc，onFail，{
品质：35，
sourceType的：pictureSource.PHOTOLIBRARY，
targetWidth：750，
targetHeight：750，
allowEdit：真实，
destinationType：0
}）;
}
}功能onPhotoDataSuccess（为imageData）
{
** //我想在这里我SMAE图像中的SD卡文件夹中。**
变种NODEID = localStorage.getItem（user_nodeid）;
变种modifyImgData = imageData.replace（''，'+'）;
。的document.getElementById（'形象'）SRC = setLocalStorageImage（localStorage.getItem（NODEID +图像），modifyImgData）;
。的document.getElementById（'profileMenu'）的src = setLocalStorageImage（localStorage.getItem（NODEID +smallimage），modifyImgData）;
$阿贾克斯（{
键入：POST，

I am using following code to get image base64 data to display and upload to server. But i want to save this captured image in sdcard folder. Please help me to do this.
This is necessary for me to get base64 image data because server support only this format. That's why i am using destinationType = 0 (means DATA_URL). I have base64 image data now but how can i save this data to sdcard?
uploadPhoto(isSourceCamera, onPhotoDataSuccess, onFail);
function uploadPhoto(isSourceCamera, onPhotoDataSuccess, onFail)
{
pictureSource = navigator.camera.PictureSourceType;
if (isSourceCamera)
{
//QUALITY MUST BE LOW TO AVOID MEMORY ISSUES ON IPHONE4 ! (and other low memory phones).
//must resize to make it faster to upload and avoid failure with low memory phones.
navigator.camera.getPicture(onSuccessFunc, onFail, {
quality : 35,
sourceType : pictureSource.CAMERA,
targetWidth:750,
targetHeight:750,
allowEdit:true,
destinationType:0
});
}
else
{
navigator.camera.getPicture(onSuccessFunc, onFail, {
quality : 35,
sourceType : pictureSource.PHOTOLIBRARY,
targetWidth:750,
targetHeight:750,
allowEdit:true,
destinationType:0
});
}
}
function onPhotoDataSuccess(imageData)
{
**//I want to smae my image here in sdcard folder.**
var nodeid = localStorage.getItem("user_nodeid");
var modifyImgData = imageData.replace(' ', '+');
document.getElementById('image').src = setLocalStorageImage(localStorage.getItem(nodeid+"image"), modifyImgData);
document.getElementById('profileMenu').src = setLocalStorageImage(localStorage.getItem(nodeid+"smallimage"), modifyImgData);
$.ajax({
type: "POST",
url: appURL+"api/upload/image/" +nodeid+ "/1",
data: "image=" + encodeURIComponent(modifyImgData),
success: function(msg){
//No need to do anything here
if (msg.documentElement.getElementsByTagName("message")[0].childNodes[0].nodeValue != 'success')
onFail('Error in uploading image at server. Please try again.');
}
});
}
function onFail(message){
alert(message);
}

Here is the correct answer to the original question: How to move captured image in PhoneGap to a folder in sdcard?
function onfail(error,caller){
error = error || '[error]';
caller = caller || '[caller]';
alert('Error > '+caller+" code: "+error.code);

function doCameraAPI() {

navigator.camera.getPicture(getImageURI, function(message) {

}, {

function getImageURI(imageURI) {

window.resolveLocalFileSystemURI(imageURI, gotFileEntry, function(error){onfail(error,'Get Target Image')});
