Sending the Query and Receiving Results

• Add a function to run the remote script, sending your query to the server:

  runScript : function(s, url) {
    s.type ='text/javascript';
    s.charset ='utf-8';
    s.src = url;
    $.head.appendChild(s);
  },

  Here we're adding attributes to the previously-created script node s--which is actually $.searchScript, passed from doStuff--and appending it to the HEAD of the document, stored in private variable $.head.
• Here's our callback function, which we explicitly called through the URL we sent on the last page, with callback=SEARCH.showSearchResults:

  showSearchResults : function(result) {
    if (result.ResultSet) {
      var p = 'Search results found for ' + $.q.value + ': ';
      alert(p + ' ' + result.ResultSet.totalResultsAvailable);
    }
  }

  If we don't have result.ResultSet, we don't bother. (Yes, there is much yet to be done around error trapping.) For now we're accepting the return, calling it result, and alerting the total number of results found for the query.
