 <apex:selectList id="ch" value="{!num}" multiselect="false" size="1">
            <apex:selectOption itemValue="" itemLabel=""/>
            <apex:selectOption itemValue="01" itemLabel="01"/>
            <apex:selectOption itemValue="01" itemLabel="02"/>
  </apex:selectList>
<apex:CommandLink onclick="return validate()">click</apex:CommandLink>                 <script language="javascript">
                       function validate()                
                        {                    
                            try  
                            {
                                alert("Hi "+document.getElementById("{!$Component.ch}").value)
                                return false;
                            }
                            catch(e)

I've tried your code in IE8, firefox and chrome and it works as expected once I'd fixed a couple of things:

 

 

  • Your apex:form tag is missing the left angled bracket to close the tag
  • The final tag of the page should be closing apex:page, not just page
  • The final ItemValue is 01, but the label is 02.

            <apex:selectOption itemValue="02" itemLabel="02"/>
  </apex:selectRadio>
<apex:CommandLink onclick="return validate()">click</apex:CommandLink>  
<script language="javascript">                       
function validate()                                        
{                                                
try                              
{                                
alert("Hi "+document.getElementById("{!$Component.ch}").value)                                
return false;                            
}

{                                                        
alert(e);                                                        
return false;
