How to download a file using javascript

Hi Helen,

Remove header for authorization please.
It's generated based on user name and password so you can't just copy it from another app.

Hi,
I'm not sure where you're referring to regarding header authorization.
Here's my sample code:
pre
//alert('Device ready, download to follow');

function successDownload(entry) {
alert("download complete: " + entry.fullPath);
}

function failDownload(error) {
alert("An error has occurred: Code = " + error.code);
alert("upload error source " + error.source);
alert("upload error target " + error.target);
}

var fileTransfer = new FileTransfer();
alert('FileTransfer instantiated.');

var uri = encodeURI("http://www.goldbeltbyway.com/sites/default/files/uploads/shelf1.jpg");
var filePath = 'file://data/shelf1.jpg';

fileTransfer.download(uri, filePath, successDownload, failDownload);

/pre

Hi Helen,

This code won't work on preview, this is for device only.
Is the path "file://data/" available on your device?

[Helen]

Hi Katya,
Yep, i've installed the .apk on Android phone, also tried viewing using Appery Test app for android.
Yes, path /data is available.
I get some 2 errors noted above about 'download error source', ,download error target....

Thanks,
Helen

Hello! In JS above there is incorrect path to the file:
codevar filePath = 'file://data/shelf1.jpg';/code
should be
codevar filePath = 'file://sdcard/data/shelf1.jpg';/code

[Helen]

Hi Marina,

I added 'sdcard' to filePath above, I get the same errors.
I tested using both Appery Test App and install .apk to device.

Thnx

Hi, this code works for us if install .apk on device:
codefunction successDownload(entry) {
alert("download complete: " + entry.fullPath);
}
function failDownload(error) {
alert("An error has occurred: Code = " + error.code);
alert("upload error source " + error.source);
alert("upload error target " + error.target);
}
var fileTransfer = new FileTransfer();
alert('FileTransfer instantiated.');
var uri = encodeURI("http://www.goldbeltbyway.com/sites/default/files/uploads/shelf1.jpg");
var filePath = 'file://sdcard/data/shelf1.jpg';
fileTransfer.download(uri, filePath, successDownload, failDownload);/code
Please clarify what is the error you get and what device/version you use?

[Helen]

Thanks Marina, however it's still not working for me.

I installed .apk on Motorola Droid Bionic, version 4.1.2.

Code is now in onclick event of a button... does this make a difference?

Thanks!

Hi Helen,

Do you see any error messages?

[Helen]

Yes, same errors as mentioned above.

I realize code 3 is connection error. I'm not so familiar with mobile devices, I checked settings that would perhaps limit downloads, but do not notice anything obvious.

Thanks!
