split the url and then look for the variable:

fooExists = 0;
urlvars = document.URL.split("?");
  if(urlvars[1]){
   urlPairs = urlvars[1].split("&");
    for(i=0; i<urlPairs.length; i++){
     if (urlPairs[i].indexOf('foo=')) {
       fooExists = 1;
     }    
   }

if (fooExists) {
        doSomething();
}
