jQuery loop over JSON result from AJAX Success

Question

On the jQuery AJAX success callback I want to loop over the results of the object      This is an example of how the response looks in Firebug        TEST1  45  TEST2  23  TEST3   DATA1       TEST1  46  TEST2  24  TEST3   DATA2       TEST1  47  TEST2  25  TEST3   DATA3       How can I loop over the results so that I would have access to each of the elements  I have tried something like below but this does not seem to be working   jQuery each data  function index  itemData         itemData TEST1      itemData TEST2      itemData TEST3

This is what I came up with to easily view all data values:

_x000D_

var dataItems = "";_x000D_
$.each(data, function (index, itemData) {_x000D_
    dataItems += index + ": " + itemData + "\n";_x000D_
});_x000D_
console.log(dataItems);

_x000D_

each will work   Another option is jQuery Ajax Callback for array result  function displayResultForLog result      if  result hasOwnProperty  d          result   result d        if  result     undefined  amp  amp  result    null        if  result hasOwnProperty  length            if  result length  gt   1            for  i   0  i  lt  result length  i                var sentDate   result i                     else             requiredTable  append  Length is 0                  else           requiredTable  append  Length is not available                else         requiredTable  append  Result is null

You can also use the getJSON function         getJSON   your script php   function data              each data  function index                alert data index  TEST1               alert data index  TEST2                         This is really just a rewording of ifesdjeen s answer  but I thought it might be helpful to people

For anyone else stuck with this  it s probably not working because the ajax call is interpreting your returned data as text - i e  it s not yet a JSON object   You can convert it to a JSON object by manually using the parseJSON command or simply adding the dataType   json  property to your ajax call  e g   jQuery ajax       type   POST       url    lt  php echo admin url  admin-ajax php      gt        data  data       dataType   json         ensure you add this line        success  function data            jQuery each data  function index  item                  now you can access properties using dot notation                        error  function XMLHttpRequest  textStatus  errorThrown            alert  some error

if you don t want alert  that is u want html  then do this            each data  function index                pr result   append data index  dbcolumn                 NOTE  use  append  not  html  else the last result is what you will be seeing on your html view  then your html code should look like this       lt div id  pr result  gt  lt  div gt        You can also style  add class  the div in the jquery before it renders as html

you can remove the outer loop and replace this with data data     each data data  function k  v            do stuff       You were close     each data  function         each this  function k  v            do stuff             You have an array of objects maps so the outer loop iterates over those  The inner loop iterates over the properties on each object element
