using javascript within $ajax->remoteFunction

[David Roda]

Hello all,

I have a textbox that, onblur, needs to use ajax to call an action
with its value as a parameter.

now ideally this would be accomplished with

onblue="<?php echo $ajax->remoteFunction(array('url'=>array
('controller'=>'ratings','action'=>'rateItem',VALUE_GOES_HERE))); ?>"

I've tried replacing VALUE_GOES_HERE with 'this.value', this.value,
$javascript->codeBlock('this.value') and none of them work properly.

It seems like there would be a way to do this with cake.  I've
currently solved the problem with a work around by taking the
javascript code generated by cake and copying and pasting it in place
of the $ajax->remoteFunction code.  This way I can use this.value.

The result looks like this:

onblur = "new Ajax.Request('/charity/ratings/rateItem/' + this.value,
{asynchronous:true, evalScripts:true})"

This works... but I don't like breaking cake convention and it seems
as though there should be a "correct" way of doing this.

Does anybody know if there is?

Thanks in advance!

Dave

With the corresponding view to the remote function
call set a variable in a hidden field.  And then, in the
"oncomplete" attribute, use something like
Form.Element.setValue('YourField', $F('HiddenField'));

Best regards.

I'm sorry I think you misunderstood my question

I am trying to figure out how to pass a javascript value from the page which calls the ajax function. 

I was able to do this by copying and pasting the javascript generated by the CakePHP Ajax helper and modifying it, but I am looking for a way to do this within the framework because from what I gather pretty much anything you need to do you can do with the CakePHP built in methods.
