Question

I am using codeigniter framework and in view i am using jquery. Now, I have one select box which contains values from database. I tested the values of it using jquery change event and alert box. Its giving exact value in alert box on change, but when i am using post method or get or even $.ajax(), its not giving any output. In fact i checked with console.log(), its not going inside that too. I just need to post some values and get some info from database to show in the div just below that select box.
Here’s the code for jquery:

$(document).ready(function(){
   $('#org_name').change(function(){
       $.post('index.php/contact/getorg',{'query':$('#org_name').val()},function(data){
         console.log("inside post"); 
         $('#showorg').html(data);
         console.log(org_name);
       });//close post function
   }); //close org_name event function
});

I am always using the following style…

ajax({
   type: "POST",
   url: 'index.php/contact/getorg',
   data: JSON.stringify({'query':$('#org_name').val()}),
   dataType: "json",
   contentType: "application/json; charset=utf-8",
   success: function (data) {
      $('#showorg').html(JSON.parse(data.d));
   },
   error: showError
};

function showError(responseText, statusText, xhr, $form) {
            debugger;         }

EDIT:

And also the line console.log(org_name); seems not correct. Where is the member org_name comming from?
