I was hanging out on Google  then I found your question and it s very simple to parse JSON response into normal HTML  Just use this little JavaScript code      lt  DOCTYPE html gt   lt html gt   lt body gt    lt h2 gt Create Object from JSON String lt  h2 gt    lt p id  demo  gt  lt  p gt    lt script gt   var obj   JSON parse     name   John    age  30   city   New York      document getElementById  demo   innerHTML   obj name          obj age    lt  script gt    lt  body gt   lt  html gt

Original question was to parse a list of topics  however starting with the original example to have a function return a single value may also useful   To that end  here is an example of  one way  to do that       lt script type  text javascript  gt      function getSingleValueUsingJQuery           var value             var url    rest endpointName     document getElementById  someJSPFieldName   value        jQuery ajax           type   GET           url  url          async  false          contentType   application json           dataType   json           success  function json              console log json value        needs to match the payload  i e  json must have  value   foo             value   json value                     error  function e              console log  jQuery error message     e message                             return value             lt  script gt

The data returned by the JSON is in json format   which is simply an arrays of values  Thats why you are seeing  object Object   object Object   object Object     You have to iterate through that values to get actuall value  Like the following  jQuery provides   each   for iterations  so you could also do this     getJSON  url with json here   function data         each data  function  linktext  link            console log linktext           console log link                 Now just create an Hyperlink using that info
