Remove an option from a Visual force SelectList SelectOption

Question

I have a VisualForce page where I am using SelectList and SelectOption. For example if my SelectOption list contians Option 1 Option 2 Option 3

I need to remove Option 2 on the page by its value not by index. I can add validation in my controller, but I wanted to do it on the page since I plan on reusing the selectlist.

<apex:selectList id="recordTypeSelect" value="{!currentCaseObject.RecordTypeId}"  >
     <apex:selectOptions value="{!newVisaTypesList}" id="visaoptionid"/>                                                                                                                      
</apex:selectList>

Answer 1

So I tried this in the page and it worked.

<script>
var x= document.getElementById("page:inputForm:recordTypeSelect");
for (var i=0; i<x.length; i++){
if(x.options[i].text == 'Value to be removed')
    x.remove(i);
}   
</script>

You can add logic in the controller in the get method of your list .

e.g.

public List<SelectOption> newVisaTypesList{
    get 
    {
       list<SelectOption> pOptions = new list<SelectOption>();  
    if(condition)
        pOptions.add(new SelectOption('1', '1')); 
    if(condition)
            pOptions.add(new SelectOption('2', '2')); 
        return pOptions;          
    }
    set;
    }
