get selected item from selectList and passing to controller

Question

I'm trying to get the value of selected list and passing it to the controller but my code does not work ! I have tried to do this.

<apex:selectList value="{!facility}" size="1">
                   <apex:selectOptions value="{!FacilityOptions}" />
                   <apex:actionSupport event="onchange">
                       <apex:param name="selectedVal" value="{!facility.Name__c}" assignTo="{!facilityName}"/>
                   </apex:actionSupport>
 </apex:selectList> 

Controller:

public List<Facility__c> facilities {set; get;}
public Facility__c facility {get;set;}

 public List<SelectOption> getFacilityOptions() {

    List<SelectOption> options = new List<SelectOption>();
    for (Facility__c record : getfacilities())
    {
        options.add(new SelectOption(record.Name,record.Name__c));
    }
    return options;
    }


public List<Facility__c> getfacilities(){
   facilities = [SELECT Name,Name__c FROM Facility__c];

   return facilities;
}

I guess you are missing the action parameter of the actionSupport tag of visualforce. Try calling a method in action parameter of actionsupport and take a look at the value of variable in debug logs. Also you can perform operations in that method you wish to do on change event.
