Hi,

I would like to use JBatchUpload in my ASP.NET web page. For that, I would like to know if there is a way to have events in javascipt in order to detect for example when one file has completed uploading and when the whole batch is done.
For example, I would like to process the files one by one as they are sent. I think this is done by specifying a URL in the parameter url. But then, once all the batch has been completed, I need to perform a special postback to display the results on screen. In fact, it would be like simulating a button click and then in the code-behind, I would handle the event of the click.
My question is basically: can I have a javascript method called when the batch is done?

Thanks,
Talal

Answer is Yes with JSAPI:
http://www.jfileupload.com/products/tools/index.html

Install JBatchUpload over JSAPI and you will have the following JavaScript callbacks:

Code: Select all

function JSTransferTriggered(filelist)
{
}

function JSTransferStarted(filename, filesize)
{
}

function JSTransferCompleted(filename)
{
}

function JSTransferCancelled()
{
}

function JSTransferFailed(errormsg)
{
}

function JSTransferDone(filelist)
{
}

Does it help ?

Yes, I figured it thanks!

I am now trying to integrate the control into one of my pages. I need to add a parameter to the call of the upload URL. How could I do that with the javascript code?
I tried getting rid of the javascript code by inserting directly the object tag and applet tag into the ASPX html code. but as soon as i hit upload, it hangs. nothing happens. I am sure it's because of my transformation of the code because I have used for testing, the page that you provide as an example, except that I replace the script call to the JS page, by the direct declaration.
Why is this an issue? am I missing something?
do you have an example of such a declaration without javascript?

I am using WeakSSL and JSAPI.

The code that I have is the following:

Code: Select all

Hi again,

I managed to make the javascript work as it is given in the example.

I would like to know how I can modify the buttons (select, start, cancel) I would like to disable the select and start when the user clicks on cancel. So in general, how do we work with the controls in the applet?

Thanks,
Talal

You can customize the UI thanks to i18n_pane.properties and i18n_bar.properties text files. You have a tutorial at:
http://www.jfileupload.com/products/jfi ... ation.html

Is it enough to do what you need ?

Thanks, I was already looking at these files but none of my changes (even small ones, like text change) were not working. I will have a look again at it today maybe it was a problem of cache or something.

I have deployed my website on the test server and I keep getting error 302 after the first upload finishes. I thought it was due to the integration I made of the java control into one of my pages, so I tried using the provided applet_http_aspx.html file, with some modification to user weakssl and jsapi, but still the same problem happens.

Also, we have bought the jfileupload and the jbatchupload. I copied the corresponding jars of each zip file and overwrote the one I was using from the demo project. but I still keep getting "unregistered" in the control. Is there something else I have to do to make this work? we need to release the project onto the client's server and we cannot do so with "unregistered". Weird as it may seem, I am not getting error 302 on the client's server! Only on our test server.
Any quick help is much appreciated.

Thanks,
Talal

Hi again,

I am now able to make the registered jars work without the jsapi. This is what I have done:
I created a new webfolder. I first copied the jfileupload files in int (registered) and tested, it worked fine, the applet appears. I have added the batch upload from the package that we bought yesterday and it also worked. After that, I added weakssl.jar and tried accessing using https, and it worked well. Now, I copied the jsapi.jar and its html and js files into the webfolder and this is the error I get:

I don't get it. The exact same files in unregistered mode are working well in another web folder. I copied those files into the new folder that I created and i got the same error. How can the exact same files produce an error in one folder and no error in another folder?? I have checked the size, it's the same to the byte.

thanks,
Talal

I've sent you the Enterprise version of JSAPI, it should work now.

Posted: **Tue May 26, 2009 5:51 pm**

i am having a simular issue - the red unregistered message has gone but the blue one remains - is this due to the jsapi?
thanks,
Josh

No, it's not because of JSAPI. Which license do you have ? Pro ? Do you have one license for each product ?
