Question

I am developing a web application and i am integrating jquery in it… Now looking for ajax calls with jquery to my controller function….

jquery.ajax() would be useful i think so… But how to call my controller method….

$.ajax({
        type: "POST",
        url: "http://localhost/codeigniter_cup_myth_new/index.php/libraryController/loadbookdetails",
        data: "",
        contentType: "application/json; charset=utf-8",
        async: false,
        dataType: "json",
        success: function(jsonObj) {

function loadbookdetails()
{
    //Paging 
        $college=$_SESSION['college'];
        $this->load->library('pagination');
        $data['bookdetails'] = $this->librarymodel->selectbook($college);
        //$data['rackOptionData'] = $this->librarymodel->selectrack();
         if(empty($data['bookdetails']))
          {
             $data['comment'] = 'no record found!';
          }

        $this->load->view('bookdetials',$data);
}

I am fetching this records here how to use it with jquery.ajax() function and how to convert $data to json and use it with jquery and iterate with a table…

You can’t directly interface jQuery to PHP functions, because they don’t run at the same time: PHP is executed on the server side (and usually generates the HTML page), jQuery is run on the client side.

You would have jQuery make an Ajax call to a PHP page’s URL. That PHP page would the desired controller, and perform the requested action(s).

Whether there is a pre-defined way to do that depends on what PHP Framework you are using (if any).
