[Proto-Scripty] Ajax upload
I am new to prototype JS library feature.
I want to implement ajax upload feature in my web application. For
that,
1) I wrote a servlet which copies the file to a particular folder in
server.
2) HTML form, I have a upload control and a Button which fires an ajax
request. Below is the code on the button
new Ajax.Request('http://isgdev.synygy.net/servlet/
CommonsFileUploadServlet',
{
method: post,
onSuccess: function(transport){
var response = transport.responseText || no response text;
alert(Check-! \n\n + response);
},
onFailure: function(){ alert('Something went wrong...') }
});
When I click the button, the servlet is called but the selected file
is not copied to server.
But, When I submit the form, through regular post method (without
using ajax). The servlet works properly and the file is copied to
server properly.
Can you please guide me on this.

[Proto-Scripty] Behavior of Element.select different in 1.7
Hi,
I'm using the following statement in Prototype 1.6.1 to hide an image:
$('MyContainerId').select('img[src=images/icons16/
btn_add.gif]').invoke('hide');
but after updating to 1.7 the select statement returns [] instead if
the image object.
Is this a problem of 1.7 or have I used the select function in a wrong
way?
I've tested this code in IE8 and Firefox 3.6. The html looks like
this:
img border=0 align=absmiddle title=Remove src=images/icons16/
btn_add.gif
Thanks

[Proto-Scripty] Re: Behavior of Element.select different in 1.7
Hi,
My suspicion is if you change your selector to use $= rather than =
(e.g., 'img[src$=images/icons16/btn_add.gif]'), it'll start working
again. The $= operator looks for an attribute _ending_ in the given
string rather than _equalling_ it.[1]
I haven't looked into it, but my guess offhand is that the selector
engine in 1.7 is matching against the image's fully-resolved URL,
whereas 1.6's old engine was using the relative URL in the attribute.
FWIW, it's easily replicated:
Using 1.6.1 and =, works: http://jsbin.com/ewire5/
Using 1.7 and =, doesn't work: http://jsbin.com/ewire5/2
Using 1.7 and $=, works: http://jsbin.com/ewire5/2

[Proto-Scripty] Re: Behavior of Element.select different in 1.7
Hi,
Sorry, that list should have been:
Using 1.6.1 and =, works: http://jsbin.com/ewire5/
Using 1.7 and =, doesn't work: http://jsbin.com/ewire5/2
Using 1.7 and $=, works: http://jsbin.com/ewire5/3
I'm sure everyone figured that out.
And this may be of interest: http://jsbin.com/ewire5/4
My guess is that the old engine used `getAttribute('src')` and/or
`readAttribute('src')`, but the new engine uses `src` directly. The
old behavior is probably more correct; the new behavior may be more
useful though... ;-)

Sure. With the exception of bleeding-edge browsers (WebKit nightlies,
mostly), JavaScript is prevented from sending files over
XMLHTTPRequest for security reasons. Most Ajax file uploads fake
their way around this by using hidden iframe elements as the actual
form target, and a callback from within that iframe to the parent page
to handle the response from the server.

The final step in any of the hiding Effects is to use Prototype
hide() on the event, removing it from view with display:none. You
might want to try Effect.Morph instead.

[Proto-Scripty] Re: event on leaving page
One note on TJ's post, hopefully helpful: You cannot CANCEL the unload event. If i understand them correctly, load and unload are the only native events that can't be canceled from scripts. You can perform other actions, but unload means the browser has been committed to unloading that page, regardless what else it's told to do at that point. The point of no return to let the user cancel the unload is beforeunload (handy, and a Microsoft creation, ironically). And to his point, he's correct: about the only other actions you can take are cleanup/garbage collection. Not that it would matter anyway if you create new content, the page is going bye-bye. :) That all comes from a painful two weeks a few years ago before i knew about beforeunload. Still bitter at myself over that. -joe t. On Mar 10, 9:31 am, Walter Lee Davis wa...@wdstudio.com wrote: On Mar 10, 2011, at 2:25 AM, T.J.
