does every element in your VF page have an ID?you may need to select it like  thepage:theform:theelement:theitem and drill down to it.

 

This issue is exaclty why I use JQUERY, much eaiser...

This is a javascript solution

 

<script type="text/javascript">
   function abcd(id)
     {
       var temp=document.getElementById(id).value;
       if(temp==null||temp=='')
       {
         alert("Empty Organization Name");
         return false;
        }
		else
		{
			validatedAction();
		}
     }

</script>
<apex:form id="formPranav">
<apex:actionFunction name="validatedAction" action="{!save}" />
            <td>Oraganization Name :</td>
            <td><apex:inputText id="txtOrgName" value="{!str_OrgName}"/></td>
</apex:form>

<apex:commandButton onclick="abcd('{!$Componenet.txtOrgName}')" value="Save" />
