title: Determine Field ID for Column in SharePoint 2013 List
body: <p>I am trying to use SPServices UpdateList operation, and I need the Field ID for my column that I want to change from the default read only setting.  How do you determine the Field tag settings?</p>
  
  <pre><code>//Make the author field editable
  var author = "&lt;Fields&gt;&lt;Method ID='1'&gt;&lt;Field /*What stuff goes here?*/ ReadOnly='FALSE' /&gt;&lt;/Method&gt;&lt;/Fields&gt;";
  $().SPServices({
      operation: "UpdateList",
      listName: "Requests",
      listProperties:"",
      updateFields: author,
      newFields: "",
      deleteFields: "",
      listVersion: "",
      async: false,
      completefunc: function (xData, Status){  
      }
  });
  </code></pre>
