php - Ajax Json data - How to access the returned Json data -


when click on listproduct (which invoice no) open collapsible table listing products matching invoice no.

my view file:

<script> $(document).ready(function(){     $(".listproduct").click(function(){         var value = $(this).text();         alert(value);         $.post('<?=site_url("purchase_controller/getproductlist"); ?>', {data:value},function (result) {             alert(result[1][1]["invoiceno"]);              for(i=1;i<result["count"];i++){ //loop trough elements                 $('#products tr:last').after('<tr><td>' + result[i]['invoiceno'] + '</td><td>' + result[i]['productname'] + '</td><td>' +   result[i]['price'] + '</td></tr>');             }         });          $(".collapse").collapse('toggle');     }); }); </script>  <table id="products">     <tbody>         <tr>             <td >invoice no</td>             <td>productname</td>             <td> quantity</td>             <td> price</td>             <td> amount</td>         </tr>     </tbody> </table>

my controller file: 

public function getproductlist(){     // check if ajax request     // if($this->input->is_ajax_request()){     // echo "entered";      // checks if variable data exists on posted data     if($this->input->post('data')){         //query in model should verify if data passed legit before querying         $query = $this->purchasemodel->getproductlists($this->input->post('data'));         $data['records'] = $query['records'];         $data['count'] = $query['count'];          $this->output->set_content_type('application/json');         $this->output->set_output(json_encode($data));          return $data;     }     // } }

my output when debugged - response ajax: 

{ "records": [     {"id":"39","invoiceno":"55","price":"30000","quantity":"2", "amount":"60000","productname":"tab"},     {"id":"41","invoiceno":"55", "price":"200","quantity":"4","amount":"800","prod    uctname":"zdsfs"}   ],   "count":2 }

but error getting:

typeerror: result[1] undefined  alert(result[1][1]["invoiceno"]);

jquery's parsejson() function parse json string.

var resultobj = $.parsejson( result ); alert(resultobj.records[1].invoiceno);
