How to use getJSON sending data with post method

Question

I am using above method  amp  it works well with one parameter in URL   e g  Students getstud 1 where controller action parameter format is applied   Now I have an action in Students controller that accepts two parameters and return a JSON object   So how do I post data with   getJSON   using post method   Similar methods are also acceptable   The point is to call an action of the controller with AJAX

The   getJSON   method does an HTTP GET and not POST   You need to use   post      post url  dataToBeSent  function data  textStatus        data contains the JSON object     textStatus contains the status  success  error  etc     json      In that call  dataToBeSent could be anything you want  although if are sending the contents of a an html form  you can use the serialize method to create the data for the POST from your form   var dataToBeSent      form   serialize

getJSON   is pretty handy for sending an AJAX request and getting back JSON data as a response  Alas  the jQuery documentation lacks a sister function that should be named   postJSON    Why not just use   getJSON   and be done with it  Well  perhaps you want to send a large amount of data or  in my case  IE7 just doesn   t want to work properly with a GET request   It is true  there is currently no   postJSON   method  but you can accomplish the same thing by specifying a fourth parameter  type  in the   post   function   My code looked like this     post  script php   data  function response         Do something with the request     json

This is my  one-line  solution     postJSON   function url  data  func      post url  url indexOf         -1           amp     callback     data  func   json        In order to use jsonp  and POST method  this function adds the  callback  GET parameter to the URL  This is the way to use it     postJSON  http   example com json php    id   287    function  data       console log data name         The server must be prepared to handle the callback GET parameter and return the json string as   jsonp000000    name   John    age   25      in which  jsonp000000  is the callback GET value   In PHP the implementation would be like   print r   GET  callback       json encode  myarr           I made some cross-domain tests and it seems to work  Still need more testing though

Just add these lines to your  lt script gt   somewhere after jQuery is loaded but before posting anything       postJSON   function url  data  func          post url  data  func   json        Replace  some all    getJSON with   postJSON and enjoy   You can use the same Javascript callback functions as with   getJSON  No server-side change is needed   Well  I always recommend using   REQUEST in PHP  http   php net manual en reserved variables request php  Among   REQUEST    GET and   POST which one is the fastest    This is simpler than  lepe s solution
