Owkay i currently have a list of checkboxes called: option\_ids[], this  
will give me a nice array of the options selected. How ever… every  
time the user chnages their options an ajax request should be made, as  
follows:

\<%= observe\_field(“option\_ids[]”,  
:frequency =\> 0.25,  
:update =\> “infoprijs”,  
:url =\> { :action =\> :getprijs },  
:with =\> “formdata = Form.serialize(‘bestel’)”) %\>

Owkay, it submited while i wasnt done typing yet… My bad 🙂

Problem with the code above is that it only handles the ajax request  
when the FIRST checkbox is changed, this because all the check boxes  
have the same name/id… Is there any way to fix this without making the  
same amount of ajax statements as there are checkboxes, cause i’d think  
thats a very unefficient solution.
