Re: Ajaxcfc newbe problems (2)
Ioannis,
Several folks on the ajaxCFC mailing list have commented on
documentation like you suggest, but nobody (as far as I know; myself
included) has stepped up to the plate to help Rob with documentation
despite a desire to do so. I'm guessing that folks are just really busy.
I agree that some time should be made for documentation.
As for debugging your code, all you did to the code you posted below was
change this:
function jsReturn(r) {
sDumper(r);
}
to this:
function jsReturn(r) {
document.write(r);
}
and that's all? That produces the error you got? Hmm... what does firebug
say? What version of firebug are you using? If you're not using the beta, you
might want to grab it from getfirebug.org... it's very slick.
I'd be interested to know what it has to say. Have you tried this in IE? Does
it produce similar results?
What happens if you replace document.write(r) with alert(r)? BTW, I'm not sure
anyone uses document.write for much. I could be wrong there, though.
Cheers,
Chris

Hello everyone for once again,
After the extremely helpful comments of Dan (the fireGub enlightment) and,
Chris and Jordan on the actual use of ajaxCFC, I have manage to move on
another issue. The idea of Ajax is quite clear at the moment in my head and
I have manage to make a request to the server, receive a response and handle
it almost.
The following example worked 100% ok:
test.cfc
cfcomponent extends=ajax
cffunction name=GetCurrentTime returntype=string output=true
cfset var szTime = TimeFormat(Now(), h:mm:ss tt)
cfsavecontent variable=jsReturncfoutput
Aftin tin ora:#szTime# Ton lene h1PSILO/h1
/cfoutput/cfsavecontent
cfreturn jsReturn /
/cffunction
/cfcomponent
- - - - - - -
test.cfm
!--script type=text/javascript
function content() {
// send data to CF
DWRUtil.useLoadingMessage();
DWREngine._execute(_ajaxConfig._cfscriptLocation, null, 'GetCurrentTime',
null, jsReturn);
}
function jsReturn(r) {
sDumper(r);
}
/script
/head
body
a href=#class=linksonClick='content();'pos ton lene/a/li--
- - - -
When I am trying to replace the sDumper(r) with document.write(r);
then I am getiing the most unsuall alert message
typeError: $(disabledZone)has no properties and even though the requested
content displayed the browser keeps loading for ever and freezes (you cannot
refresh it).
I ve check the internet for the error but no much of a result.
Any ideas more than welcome.
( I am thinking to document a Ajaxcfc newbie problems trilogy )
Please participate
hahaha
thanx Ioannis

Re: Ajaxcfc newbe problems (2)
It works smoothly with alert(r);
Any other way to try to display it ?( what I want to do is to display the
results of the output form my server to a specific DIV on my first page. The
page is kind of dynamic content displaying info).
I am using the Beta version as you said. The errors I am getiing are:
a)On the console tag: the request field is keep loading for ever even thought
the requested content has been dispalyed in my screen already.
b)On the Script tag the debbuger has stoped on util.js, line 271
$('disabledZone').style.visibility = 'hidden';
this probably produses the alert I had mention before.
Do you think my javascript synatax is wrong (my level is quite basic on
Javascript)
Thanx a a lot

RE: Ajaxcfc newbe problems (2)
Replace document.write(r);
With
DWRUtil.setValue(myDivName,r);
Does that work?

Re: Ajaxcfc newbe problems (2)
Yeees, it worked it worked it worked it worked it worked. Any suggested reading you have to reccomend on how to send and handle requestes with AjaxCFC would be more than welcome. As well the reason of why a simple document.write wouldnt work (in order to avoid similar mistakes in the future). Thanx a lot guys for everything. Ioannis ~| Create robust enterprise, web RIAs.

Re: Ajaxcfc newbe problems (2)
Ioannis,
I wouldn't spend a lot of time trying to figure out why document.write()
isn't working for you. It's not what you want to use anyway.
What you want to do is manipulate the DOM to update portions of the
screen dynamically -- at least it seems that's what you want. You can do
this with JavaScript, but it's rather complicated, and given your stated
level of experience with JavaScript I would suggest you look to a
JavaScript library that is written specifically to make this sort of
task easier.
My library of choice is jQuery (http://jQuery.com). It's fantastic. It
has a very active and loyal community that are willing and able to
answer any questions you'd like.
I'm coding something like what you're describing right now, and I'm
using jQuery to accomplish it. In the past I would have used IE's
innerHTML to get the job done, but that only works in IE (at least I
don't think it works in FF).
(note this snippet is not a working piece of code)
ThisRow = ;
ThisRow += div class=\OrderEntryListRow + RowClass + \
RowType=\ + RowClass + \\n;
ThisRow += span class=\Date Cell\ + ThisDate + /span \n;
ThisRow += span class=\CostCenter Cell\ + CostCenterName +
/span \n;
ThisRow += span class=\ShiftName Cell\ + ShiftName + /span \n;
ThisRow += span class=\Classification Cell\ + Classification +
/span \n;
ThisRow += span class=\Quantity Cell\ + Quantity + /span\n;
ThisRow += /div;
$(##OrderList).append(ThisRow);
You can see that I'm using normal JavaScript to create a string of HTML
which is stored as a string in the variable ThisRow. I then use jQuery
to append that string to an element. In this case that element is a div
(not shown) with an ID of OrderList. In jQuery, you can match all
elements that have a specific ID or class or attribute, etc. The
#OrderList tells it to look for an element whose ID is OrderList. I'm
using ## because I'm within ColdFusion cfoutput tags, so I need to
escape the single #.
This is a very simple example, but it does what you're looking to do.
jQuery also has ajax capability. In fact, the snippet above is in the
middle of an ajax call -- it gets executed upon success of the call.
The other good news is that Rob Gonda will soon be releasing an AjaxCFC
plug-in for jQuery! Yay! Right now, I've had to change the way I call
CFCs in jQuery, but as soon at Rob's plug-in becomes publicly available
it will change everything for ColdFusion jQuery users. I've been testing
an advanced copy and it's pretty cool stuff.
So to sum up: my advice is to check out jQuery. Sign up for the mailing
list (discuss@jQuery.com) here http://jquery.com/discuss/, and speak
up. Folks are more than willing to help new comers.
I hope this helps.
Cheers,
Chris

RE: Ajaxcfc newbe problems (2)
As well the reason of why a simple document.write wouldnt work (in order to avoid similar mistakes in the future). When document.write() is called after the page has already been displayed to the user, it rewrites the entire page. Set the innerHTML or innerText properties of a block element instead, to rewrite the contents of that element.
