My phonegap upload script works perfectly. After the upload you get a message "Please wait redirecting". I want to know how to add a redirection script so immediately after upload, it redirects to another page
var deviceReady = false;

window.setTimeout(function() {

}
Just do the page transition at the end of the success function. E.g after This line:
document.getElementById('camera_status').innerHTML = "Please wait redirecting";
Do:
window.location.href = "otherpage.html"
Or:
$('page1_div').hide();
$('page2_div').show();
Etc.

When I run this on my local server it works fine. But when I upload it to my windows 2012 R2 server I get the error
POST https://xxx/yyy/ 405 (Method Not Allowed)
I tried to play with the handler mappings in ISS and disabled WebDAV but no luck.
Since it works on the localhost but not on the windows server I figure it must be something related with the IIS setting but can not find out what.
Any help is appreciated.
In the end I found the error myself.
The settings in the web.config file where not standing correctly for FastCgiModule / StaticFileModules.
I use XMLHttpRequest to send POST data to nodejs (expressjs api). The size of file about 200mb. When I do, Chrome crashes, but the Firefox doesn't. Does Chrome have a limited file size?
And how can I upload the large file via JavaScript?
This is my code send xhr request:
// create http request API AI Engine
var xhr = new XMLHttpRequest();
xhr.open('POST', url, true);
xhr.responseType = 'arraybuffer';
xhr.timeout = 3600000;
xhr.onload = function() {
// reponse measage
if (this.status === 200) {
var errorArea = document.getElementById('error-area');
errorArea.style.display = 'none';
zip.files = {};
// unzip File
zip.loadAsync(this.response)
.then(function(zip) {
// will be called, even if content is corrupted
for (const file in zip.files) {
if (zip.files.hasOwnProperty(file)) {
const fileObject = zip.files[file];
fileObject.async('arraybuffer').then(function(fileData) {
var fileSave = new Blob([new Uint8Array(
fileData)]);
// Save file
saveAs(fileSave, fileObject.name);
})
}
}
}, function(e) {
var errorArea = document.getElementById('error-area');

Iam unable to upload pictures to a webserver with PHP backend.
My cordova camera script is able to taking the picture and show the picture in small size. But it is not able to upload an image. I dont no why. I call the function photoUpload(); and set the a onClick-event in the button like
<button class="camera-control" onclick="photoUpload();">UPLOAD</button>
Here is my JavaScript, whats wrong with it?
var pictureSource;
var destinationType;
document.addEventListener("deviceready", onDeviceReady, false);
function onDeviceReady() {
pictureSource = navigator.camera.PictureSourceType;
destinationType = navigator.camera.DestinationType;
}
function clearCache() {
navigator.camera.cleanup();
}
var retries = 0;
function onCapturePhoto(fileURI) {
$("#cameraPic").attr("src", fileURI);
var win = function (r) {
clearCache();
retries = 0;
navigator.notification.alert(
'',
onCapturePhoto,
'Der Upload wurde abgeschlossen',
'OK');
console.log(r);
}
var fail = function (error) {
navigator.notification.alert(
'Bitte versuchen Sie es noch einmal.',
onCapturePhoto,
'Ein unerwarteter Fehler ist aufgetreten',
'OK');
console.log("upload error source " + error.source);
console.log("upload error target " + error.target);
if (retries == 0) {
retries ++
setTimeout(function() {
onCapturePhoto(fileURI)
}, 1000)
} else {
retries = 0;
clearCache();
alert('Fehler!');
}
}
function photoUpload() {
var fileURI = $("#cameraPic").attr("src");
var options = new FileUploadOptions();
options.fileKey = "file";
options.fileName = fileURI.substr(fileURI.lastIndexOf('/') + 1);
options.mimeType = "image/jpeg";
options.chunkedMode = false;
var params = new Object();
params.fileKey = "file";
options.params = {}; // eig = params, if we need to send parameters to the server request
var ft = new FileTransfer();
ft.upload(fileURI, encodeURI("http://xxxx/app/upload.php"), win, fail, options);
}
}
function capturePhoto() {
navigator.camera.getPicture(onCapturePhoto, onFail, {
quality: 50,
destinationType: destinationType.FILE_URI
});
}
function getPhoto(source) {
navigator.camera.getPicture(onPhotoURISuccess, onFail, {
quality: 50,
destinationType: destinationType.FILE_URI,
sourceType: source });
}
function onFail(message) {
alert('Failed because: ' + message);
}
Look your function photoUpload is located in the function onCapturePhoto! you need to move function photoUpload on the top level.
window.photoUpload = function() {
var fileURI = $("#cameraPic").attr("src");
var options = new FileUploadOptions();
options.fileKey = "file";
options.fileName = fileURI.substr(fileURI.lastIndexOf('/') + 1);
options.mimeType = "image/jpeg";
options.chunkedMode = false;
var params = new Object();
params.fileKey = "file";
options.params = {}; // eig = params, if we need to send parameters to the server request
var ft = new FileTransfer();
ft.upload(fileURI, encodeURI("http://xxxx/app/upload.php"), win, fail, options);
}
And the better way to do it like:
<button class="camera-control" id="photoUploadButton;">UPLOAD</button>
document.getElementById("photoUploadButton").addEventListener("click", photoUpload);
I want to build a voice recorder using HTML5 same as one found in gitHub JSSoundecorder, but what I want is for the user to be able to choose the file format before recording the voice.I can do this using ffmpeg. In other words the user must be able to select the audio format by check box (mp3,wma,pcm) and in the background code, the .wav file usually created by the program instead of displaying it, it should be converted by the format selected then displayed in the new format.this is the ffmpeg code we can use ,but I don't know how to get the .wav audio file to convert it and show it.please if someone have ideas,or if can find demos I have been looking for weeks.this is the ffmpeg code:
var fileName;
var fileBuffer;
function timeToSeconds(time) {
var parts = time.split(":");
return parseFloat(parts[0]) * 60 * 60 + parseFloat(parts[1]) * 60 + parseFloat(parts[2]) + parseFloat("0." + parts[3]);

I created a page to take an image or select an image from phone gallery and works normally, but i want to upload this photo selected to my server on Godaddy.
I used Cordova file transfer to upload, install file transfer by command line :
cordova plugin add https://github.com/apache/cordova-plugin-file-transfer.git
and I put a small code to upload this photo but no message alert(No error and no Success).
the code to select an image:
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 in-line CSS rules are used to resize the image
//
largeImage.src = imageURI;
upload();
}
Code Upload function:
function upload() {
alert('large');
var uploadingImage = document.getElementById('largeImage');
var imgUrl = uploadingImage.src;
window.resolveLocalFileSystemURI(imgUrl, resolveOnSuccess, fsFail);
options = new FileUploadOptions();
// parameter name of file:
options.fileKey = "my_image";
// name of the file:
options.fileName = imgUrl.substr(imgUrl.lastIndexOf('/') + 1);
// mime type:
options.mimeType = "image/jpeg";
params = {val1: "some value", val2: "some other value"};
options.params = params;
ft = new FileTransfer();
ft.upload(fileuri, "http://siencelb.org/raycoding/insurance/avatar", success, fail, options);
}
function resolveOnSuccess(entry) {
fileuri = entry.toURL();
//use fileuri to upload image on server
}
function fsFail(message) {
alert("Error Message: " + message + "Error Code:" + message.target.error.code);
}
I have two buttons first to select an image and put it into div largeImage and this works.
second button to upload this image selected
Note: the alert('large') is displayed.
