Issues with Save intent

[hse33]

Hi,

I am trying to save an image file using the save intent. 

I am reading the file using the file-api into a blob, but when I try to activate the intent after passing this blob - I get a DOM Error 15 in Chrome (21) - the same issue happens if I try to pass it as a data url.

I have no issues with the pick intent - but this one seems to give me some real issues.

Any ideas?

My code basically gets a file system, gets a file entry, gets a file, gets a reader for this file, reads as dataurl - and sets the data url to the intent parameters object - I verified that the data url I get is correct (it displays just fie in an image DOM element)

{

                     'action': 'http://webintents.org/save',

                     'type': 'image/*',

                     'data' : theUrl

             };

Hi,

How are you invoking the inter? It needs to be in response to a user gesture - if you don't you get this error.

It is within a click handler (jquery) of an image (a button for all intents and purposes).

I tried to replace the access to the file-api to getting the data-url from the canvas instead - and I still get the same issue.

The code is within an extension - I do not know if this matters, the pick intent from within the extension works just fine.

Here is the example that gets the data-url, as it is shorter than the one that is dealing with the file-api.

Could the problem be related to the fact that I get the data via a callback? this might be related to your suggestion of having it start with a user-gesture.

$('.uploadImage').click(function(e) {

        var theUrl = this.parentNode.parentNode.getElementsByClassName('previewImg')[0].src; // get the source url of the preview-item

        getImageDataURL(theUrl, function(results){

            var params = {

                  'action': 'http://webintents.org/save', // share

                  'type': 'image/*',

                  'data' : results.data

            };

            var intent = new WebKitIntent(params);

            window.navigator.webkitStartActivity(intent, function(data) {

            });

R.

Update,

Removing the callback and doing it all inline seems to solve the issue. Thanks for the pointer.

BTW - is there a way to "suggest" a name for the file we send via the intent, maybe with a filename or title parameter for the save intent call?
