you can use http request , file static page. 

function exec_req(url) { objajax = false; if (window.xmlhttprequest) {     try     {         objajax = new xmlhttprequest();         if (objajax.overridemimetype) objajax.overridemimetype('text/xml');     }     catch(e)      {         objajax = false;     } } else if (window.activexobject) {     try      {         objajax = new activexobject("msxml2.xmlhttp");     }      catch(e)      {         try          {             objajax = new activexobject("microsoft.xmlhttp");         }         catch(e)         {             objajax = false;         }     } }  if (objajax) {    objajax.onreadystatechange = mycallback;   }     objajax.open("get", url, true);     objajax.send(); } }   function mycallback() {     if(objajax.readystate == 4 && objajax.status == 200) {         var mytext = objajax.responsetext         alert(mytext)      }      else {alert('error while reading file');}       }

just call function exec_req('bla/your_file _link.txt'), , when file'll read function mycallback invoked, , text looking available local var in function. async. not sure work locally if don't run localhost (cross origin requests supported http).
