Calling a javascript file off domain?

Hi All:

I'm trying to write a wordpress plugin that incorporates baseball-reference.com's B-R Linker (http://www.baseball-reference.com/linker/) functionality with my wordpress installation (if you follow the link - the B-R Linker is currently just a bookmarketlet - I want to have it ran automatically when hitting submit); however it does not seem to be working:

I tried to bind the javascript code to the "Submit" button on Wordpress to no avail; however if I replace the sr_link function's code with 'alert("Testing");' it works - I believe it may be an intentional "defect" of javascript to not allow running off domain scripts. If this is the case - is there any way to get around this? or can anyone tell if I am doing anything wrong? Thanks so much.

   function sr_link() { 
       var s=document.createElement("script");
       s.charset="UTF-8";
       var rand_param =    "rand=" +  Math.floor(Math.random()*10000);
       s.src="http://baseball-reference.com/linker/linker.js?"+ rand_param;
       void(document.body.appendChild(s));
   }


 jQuery(document).ready(function() {
    
    
    jQuery('#publish').bind('click', function() 
      {
      jQuery("#edButtonHTML").click();
      sr_link();  
    
    
      }); 
  });

Code (markup):

 

Does it alert "Testing" in this case:

function sr_link() { 
       var s=document.createElement("script");
       s.charset="UTF-8";
       var rand_param =    "rand=" +  Math.floor(Math.random()*10000);
       s.src="http://baseball-reference.com/linker/linker.js?"+ rand_param;
       alert("Testing");
   }


 jQuery(document).ready(function() {
    
    
    jQuery('#publish').bind('click', function() 
      {
      jQuery("#edButtonHTML").click();
      sr_link();  
    
    
      }); 
  });

Code (JavaScript):

If no, what error it shows?
