Use AJAX to validate a field

[eluser]rogierb[/eluser]
I would do something like this:

Code:

&lt;input type="text" name="zuzu" id="zuzu" onBlur="..."/&gt;<div id="ajaxreply"></div>

And I would not use the index() inside the Ajaxtst class but rather:

Code:

function check_field_something($value_to_check=null) {
   echo "this is the reply" //goes into view!
}

so I can re-use the ajax controller.

Now for the "onBlur" part. This all depends on you ajax class.
Let's dasy for arguments sake you normally use callAjax("http://somesite/ajax") as an ajax call. Now you would use

Code:

.. onBlur('http://mysite.com/ajaxtest/'+document.formname.zuzu.value())

to get a call to the controller. But it all depends on your ajax library.
