title: returning something from a promise.done in javascript
body: <p>I usually do most of whats needed in the actual .done() function of any async type calls. But in this case I want to return the string as I need it multiple places but this function returns undefined all the time. The variable is out of scope of the async call so should be available to return no?</p>
  
  <pre><code> var stringIWantBack = function getTableEditorFieldArray(pageName, tableId) {
       var searchString = 'webpagename[name ="' + pageName + '"] &gt; tableid[id ="' + tableId + '"] &gt; editor';
       var fieldArray;
       $.when(datatableUtility.GetInitStringXml())
           .done(function (returnedXml) {
               fieldArray = $(returnedXml).find(searchString).text();
               return fieldArray;
  
           })
           .fail(function (jqXhr, textStatus, errorThrown) {
               // alert("Error downloading projection data: " + textStatus + " Error: " + errorThrown);
               toastr.warning('Error downloading datatable editor fields array: ' + textStatus + ' Error: ' + errorThrown);
           });
   }
  </code></pre>
