Here is a handy script to opt in/out recipient from all subscription services within Adobe Campaign through javascript activity.

loadLibrary("/nl/core/shared/nl.js");
NL.require("/nl/core/shared/xtk.js");

/***********************************************************************
  Purpose: Opts the recipient in to all services
  Input: recipient in xml form eg <recipient @id="123"/>
  Returns: nothing
**********************************************************************/
var optInAll = function(recipient){
    var query = xtk.queryDef.create(<queryDef schema='nms:service' operation='select'>
          <select>
            <node expr='@name'/>
          </select>
          <where>
            <condition expr = "[folder/@id]<> 0 " />
            <condition expr = "[@id]<>0" />
          </where>  
          </queryDef>);
    var services = query.ExecuteQuery();
    for each(var service in services){
        nms.subscription.Subscribe(service.@name, recipient, false);
    }
} 

/***********************************************************************
  Purpose: Opts the recipient out of all services
  Input: recipient in xml form eg <recipient @id="123"/>
  Returns: nothing
**********************************************************************/
var optOutAll = function(recipient){
    var query = xtk.queryDef.create(<queryDef schema='nms:service' operation='select'>
          <select>
            <node expr='@name'/>
          </select>
          <where>
            <condition expr = "[folder/@id]<> 0 " />
            <condition expr = "[@id]<>0" />
          </where>
          </queryDef>);
    var services = query.ExecuteQuery();
    for each(var service in services){
        nms.subscription.Unsubscribe(service.@name, recipient);
    }
}  

/***********************************************************************
  Purpose: Opts the recipient in to particular services

var optinService = function(recipient, serviceName){

var optoutService = function(recipient, serviceName){

}
