problem with RJS, params and Internet Explorer

Hi,

I have some RJS code to update my select fields. It perfectly works on Firefox, but IE don't want to send params to controller.

Here is the code in view:

<%= select("incident","service_group_id", @service_groups,{:selected => 0},{   :onchange => remote_function(     :update => "incident_service_id",     :url => {:action => :update_services},     :with => "'service_group_id=' + this.value") }) %>

So in Firefox I have following params for ex.: {"action" => "update_services", "controller" => "incidents", "service_group_id" => "2"}

But in IE: {"action" => "update_services", "controller" => "incidents"}

Tested on ruby 1.8, rails 2.3.4, Firefox 3.5, Internet Explorer 6,7,8

Hope, u help me

Are you sure that this.value is the way of access a select control current value? Probably IE access it in a different way (as usual) I'd strongly recommend you to access the value using Prototype or jQuery or whatever JS library you're using.

I'm not using Prototype since a while ago, but I think this should work. http://api.prototypejs.org/dom/form/element.html#getvalue-class_method (API docs are your friend.)

<%= f.select("service_group_id", @service_groups,{:selected => 0},{   :onchange => remote_function(     :update => "incident_service_id",     :url => {:action => :update_services},     :with => "'service_group_id=' + $F('incident_service_group_id')")   }) %>

I'd tried this way, but effect is the same, IE doesn't transfer params and FF does

Did you try teh getValue() method? try this:     :with => "'service_group_id=' + $('incident_service_group_id').getValue())

Could it be concerned with session & cookies? I noticed that, when I switch authorization off, onchange event works even in IE
