title: Need to escape white space before appending to url
body: <p>This is the parameter portion of the string as I need it:</p>
  
  <pre><code>?parentId=PRICE&amp;childId=%20LIST
  </code></pre>
  
  <p>This is the parameter portion as it is (Note the missing %20):</p>
  
  <pre><code>?parentId=PRICE&amp;childId=LIST
  </code></pre>
  
  <p>Here is the function that gathers the data from two select boxes (#parentCodes and #childCodes):</p>
  
  <pre><code>            function ajaxCodeDetails(){
                  $.getJSON(
                  "manage-inventory-codes_codeDetails",
                  {'parentId': $("#parentCodes").val(),
                      'childId': $("#childCodes").val()},
                  renderDetails
              );
              }
  </code></pre>
  
  <p>How do I escape the result returned by val() before sending the request? </p>
