Get response from PHP file using AJAX

Question

So here s my issue  I am using AJAX  jQuery  to post a form to process php but the page actually needs to echo out a response such as apple or plum  I m not sure how to take the response from process php and have it stored as a variable     Here s the code I have so far    lt script type  text javascript  gt          function returnwasset                alert  return sent                  ajax                   type   POST                   url   process php                   data  somedata                  success function                          echo what the server sent back                                                     lt  script gt    Also will I need to echo the response in process php in json  or will plain text be fine   Sorry if this sounds like a stupid question  this is my first time doing something as such in Ajax   PS  How do I name the POST request in the above code

The good practice is to use like this      ajax       type   POST       url    ajax request html       data   action   test        dataType  JSON        success  function response           console log response blablabla              put on console what server sent back                and the php part is    lt  php     if isset   POST  action     amp  amp   empty   POST  action               echo json encode array  blablabla   gt  variable            gt

lt  php echo  apple     gt  is pretty much literally all you need on the server    as for the JS side  the output of the server-side script is passed as a parameter to the success handler function  so you d have  success  function data       alert data      apple

in your PHP file   when you echo your data use json encode  http   php net manual en function json-encode php   e g    lt  php   plum or data     output   array  data   plum     echo json encode  output      gt    in your javascript code  when your ajax completes the json encoded response data can be turned into an js array like this      ajax                   type   POST                   url   process php                   data  somedata                  success function json data                       var data array     parseJSON json data                          access your data like this                      var plum or whatever   data array  output                           continue from here
