Hi NOSLOW
The most important part of the code that I use is pasted below. It
comes from the view file
1.
------
This bit renders the select tag that we want to monitor. It's just a
standard select tag.
<?php
echo $html->selectTag(
'Batch/lot_number_type',
$lotNumberTypes,
null,
array(),
array(),
true
);
?>
2.
------
This is the target that the new select tag will go into:
<div id="box"></div>
3.
------
This is the observer that watches for a change in the first select tag.
When it sees a change it:
- Calls the 'url' listed below
- Which returns a rendered select tag
(that is just a regular Cake view with no layout)
- Updates the contents of div named 'box' with the returned select tag
<?php
echo $ajax->observeField(
'BatchLotNumberType',
array(
'frequency' => '1',
'url' => '/batches/get_lot_nos/',
'update' => 'box'
)
);
?>
------
Nate's approach that he posted a link to looks like it might be the
cleaner faster approach, but I haven't sat down and worked out exactly
how it works yet.
The above code works ok, and you can improve it with the various Options
that the ajax helper offers.
Hope that this is useful.
Regards,
Langdon
