How to pass parameters in ajax POST

Question

I have followed the tutorial as stated in this link  In the code below for some reason the data is not appended to the url as parameters  but if I set them directly to the url using   field1  hello  it works     ajax           url   superman           type   POST           data    field1   hello   field2    hello2             contentType   application json  charset utf-8           success  function  response                alert response status                      error  function                  alert  error

I would recommend you to make use of the   post or   get syntax of jQuery for simple cases     post  superman     field1   hello   field2    hello2         function returnedData            console log returnedData         If you need to catch the fail cases  just do this     post  superman     field1   hello   field2    hello2         function returnedData            console log returnedData      fail function          console log  error          Additionally  if you always send a JSON string  you can use   getJSON or   post with one more parameter at the very end     post  superman     field1   hello   field2    hello2          function returnedData           console log returnedData       json

Try using GET method    var request     ajax       url   url       type   GET       data    field1   hello   field2    hello2         contentType   application json  charset utf-8       request done function data             your success code here      request fail function jqXHR  textStatus             your failure code here       You cannot see parameters in URL with POST method   Edit      Deprecation Notice  The jqXHR success    jqXHR error    and   jqXHR complete   callbacks are removed as of jQuery 3 0  You can use   jqXHR done    jqXHR fail    and jqXHR always   instead

In a POST request  the parameters are sent in the body of the request  that s why you don t see them in the URL   If you want to see them  change      type   POST     to      type   GET     Note that browsers have development tools which lets you see the complete requests that your code issues  In Chrome  it s in the  Network  panel

Your code was right except you are not passing the JSON keys as strings   It should have double or single quotes around it        field1    hello    field2     hello2       ajax             type   post         url   superman         data              field1    hello      Quotes were missing          field2    hello1     Here also                success  function  response            alert response                  error  function              alert  error

Jquery ajax does not encode POST data for you automatically the way that it does for GET data     Jquery expects your data to be pre-formated to append to the request body to be sent directly across the wire   A solution is to use the jQuery param function to build a query string that most scripts that process POST requests expect     ajax       url   superman       type   POST       data  jQuery param   field1   hello   field2    hello2          contentType   application x-www-form-urlencoded  charset UTF-8       success  function  response            alert response status              error  function              alert  error                 In this case the param method formats the data to   field1 hello amp field2 hello2     The Jquery ajax documentation says that there is a flag called processData that controls whether this encoding is done automatically or not    The documentation says that it defaults to true  but that is not the behavior I observe when POST is used
