Subject: [Javascript] Prototype: events on buttons
Message-ID: <000601c8510f$11f46dd0$af24a8c0@SF2003.de>

I noticed a strange behaviour in Prototype.
I simply call a function, f.e. with an simple AJAX Request, named request():
The file's name is my_file.php.

<input type="button" name="butt1" value="request me" onclick="javascript:request();">
<input type="button" name="butt2" value="request me" onclick="request();">
<a href="javascript:request();">No button</a>

When using the link, the function works fine and Firebug shows me the correct URL of the calles AJAX script,
f.e.: http::www.mydomain.com/test/my_ajax.php

But when clicking the button, the called URL is http::www.mydomain.com/test/my_file.php and nothing happens.

It only appears when working with Prototype, it works fine with normal HTML/JS.

Is this a prototype bug or feature for input buttons?

   Additionally I found out that it only happens when the function name ist "request", so this might be a reserved name
Prototpye. But still I don't understand why it works called by a link and not by a button.

Hi,

I am trying to assign accesskey to a button using javascript dynamically using the following code

document.getElementById("testpage1").accessKey = "X";
<input type="button" id="testpage1" value="CLICK" onclick="alert('dfdf')" />

This doesn't seem to work in FireFox2. Any idea this api is supported?

TIA

Is it easy or hard to learn?
Is there a significant gain?

Well, you need to put the library file on the server but it just goes 
the same place as other JavaScript files, so you don't need any special 
access to the server.
> Is it easy or hard to learn?
Hmm. If you know JavaScript pretty well it's relatively easy, though it 
still takes some time. If you don't know JavaScript you will probably 
still be able to use many features but you might pull a little hair out.
> Is there a significant gain?
There's a huge gain in development time over just writing JavaScript, in 
my experience.
> Can animations be done with jQuery?
Yes. Some simple ones are built into the core library and others are 
available via plug-in.
> Can graphs of mathematics functions and equations be produced?
Maybe via plug-in. Check here: http://docs.jquery.com/Plugins
> Is there a good website that gives an understandable and non-technical

Define non-technical. jQuery is a JavaScript library and so any 
explanation is going to be as technical as an explanation of JavaScript. 
The jQuery site at http://jquery.com/ has the best explanation, I believe.

And though you didn't ask, there is an active community of developers 
and users and help at any level is easily available on the listserv, 
though you're expected to have put in some effort before asking for 
help, which is just good manners anyway.

In the sense that I know what it is, but I usually use Prototype
and Scriptaculous, with an occasional dollop of YUI. :-)

It's just another file to put with the rest of your JS scripts.

> Is it easy or hard to learn?
 > Is there a significant gain?

Is it easy or hard to run a marathon? :-)

I'd suggest no one can answer either of those for you -- why not
just take an hour or two to evaluate it?

As far as gain, though, being able to write, e.g.

   $('foo').hide()

versus

   document.getElementById('foo').style.display = "none"

is, to me, definitely a winner.

(That's Prototype syntax, BTW, but you get the idea.)


FWIW!

JQuery is ridiculously easy to learn. The core library, and additional 
plugins, are standard .js files you include in your webroot sub 
structure. It is incredibly powerful for something so small, can do 
animations using a variety of plugins (easing is probably one of the 
most popular), there are plugins for math functions,graphs and 
equations. The JQuery site (jquery.com) has several different areas of 
information, plus the Google Groups jquery-en list, as well as thousands 
of blog postings around the web (including a few on mine).

Subject: [Javascript] checkbox onChange delay
Message-ID: <4785729A.6070002@pulsemining.com.au>

Gday all,

I notice that this bit of code is annoyingly slow to fire in IE7, but 
works immediately in FF. Checking the box in IE does nothing at all, 
until the next click or key press. Is this just an IE bug or should I be 
using something other than onChange for checkboxes? It works fine for 
other input types. I renamed the function with the same result.

function doClose(itm) {
  vJnl   = document.getElementById("jnlamt" + itm);
  vCls   = document.getElementById("comflg" + itm);
 
  if (parseFloat(vJnl.value) != 0 ) {
    vCls.checked = false; 
    window.alert("Close not allowed if value is not zero.");
  }
}

<input type="checkbox" id="comflg1" name="comflg1" value="yes"  
onChange="doClose('1');" />
...

Regards,
Roland

Subject: [Javascript] prototype responder "un-register"
Message-ID: <004801c85c29$7550e730$af24a8c0@SF2003.de>

function refreshFavorites() {
Ajax.Responders.register({
  onCreate: function(){
    checkLogin();
  },
});



I use the checkLogin() to see if the the user is logged in and to decide wheter to fire the parent AJAX request
or to redirect to the login page.

my problem:
the checkLogin() starts an AJAX request too. Of course I would like to keep prototype for the request,
so can I unregister and then re-register the responder or is there a better way?

Is there a way to retrieve the content of an external javascript file?
That is, see its code by using alert method or something similar to it.

Firebug

Or put the external JS's address into the address bar

Here's a bookmarklet[1] I wrote a few years ago that walks over
everything that descends from the window object and attempts to
separate out functions/booleans/numbers/objects etc that are defined
in javascript and lists them in tree format. It intentionally skips
over native objects.

Its not exactly what you want, but may point you in the right direction.

               break;

               case 'before':
               new Insertion.Before($(addToElement), JSONRows);
               break;

               case 'bottom':
               new Insertion.Bottom($(addToElement), JSONRows);
               break;

             case 'top':
             new Insertion.Top($(addToElement), JSONRows);
             break;
            }
           }
          }
         }
          }
       }
      );
 }
}



ok, here is a simple trick so far:)

if($F(numRowsIndex) != numRows+1) {

instead of

          if($(numRowsIndex).value = numRows+1) {

any better ideas?
