You can append a script. It'll take a lot of script appends but you can always put a custom communication event, and only inject one good script listening to that custom event and eval()ing the event data. It will work if there's no CSP.

var RunInThisContext = function(c){ try{
    var code = document.createTextNode(c);
    var script = document.createElement('script');
    script.type='text/javascript';
    script.language='javascript';
    script.appendChild(code);
    try{document.body.appendChild(script);}catch(e){document.head.appendChild(script);}

}catch(e){ console.error('ERROR: '+e); }}; 

Use like this:

RunInThisContext('('+(function(){ 
     $('select').change();
}).toString()+'()); '); 

But bear in mind you're running this directly into the page. If page doesn't have jQuery you'll have to include it first.
