Imagine that this is your Json response

{"Visit":{"VisitId":8,"Description":"visit8"}}

This is how you parse the response and access the values

    Ext.Ajax.request({
    headers: {
        'Content-Type': 'application/json'
    },
    url: 'api/fullvisit/getfullvisit/' + visitId,
    method: 'GET',
    dataType: 'json',
    success: function (response, request) {
        obj = JSON.parse(response.responseText);
        alert(obj.Visit.VisitId);
    }
});

This will alert the VisitId field

you must parse JSON string to become object  var dataObject   jQuery parseJSON data     so you can call it like   success  function  data        var dataObject   jQuery parseJSON data       if  dataObject success    1           var insertedGoalId   dataObject inserted goal id

calling  var parsed data   JSON parse data     should result in the ability to access the data like you want   console log parsed data success     should now show  1

Use parseJSON  Look at the doc  var obj     parseJSON data     Something like this     ajax            type   POST       url    admin systemgoalssystemgoalupdate format html       data  formdata      success  function  data             console log   parseJSON data      will log Object

Since you are using   ajax  and not   getJSON  your return type is plain text  you need to now convert data into a JSON object   you can either do this by changing your   ajax to   getJSON  which is a shorthand for   ajax  only preconfigured to fetch json    Or you can parse the data string into JSON after you receive it  like so       success  function  data             var obj     parseJSON data            console log obj
