How to access an array in j-query returned by php script

Question

I want to access an array in J-query returned by PHP script via Ajax call

Ajax call for getting result from PHP script:

    $.ajax({
               url: "http://localhost/WCPM/index.php/demand/check_demand_status",
               type: 'GET',
               cache: true,
               data: {
                Meter_Group_Name: $(this).val()
               },
               success: function(data) {
               if(data["exists"]==1){
                 alert("Request already in pending for this Group");
                 $('#Meter_Group_Name').attr('selectedIndex',0);    
               }
              $("select#meter_number").html(data["option"]);
            }
    });

Response of Ajax Call from Php script:

     Array
        (
            [exists] => 1
            [option] => <option value=''>Please Select Meter</option>
<option value='5'>222000</option>
    <option value='6'>101010</option><option value='7'>34500A</option>
    <option value='13'>A00001</option><option value='14'>A11149</option>
    <option value='15'>000123</option><option value='16'>A00003</option>
    <option value='17'>A00002</option>
        )

Html Select Tag where option field to be store

   <select name="Meter_Numbers" id="meter_number"></select>

How to check data["exists"]==1 in jquery code and populate select in html with data["option"]?

Try returning the array as a json object using json_encode() — Kisuka

You can use json_encode() here like,

in js ajax function

Add type:

$.ajax({
     url:'',
     data:'',
     dataType:'json',//add this line

Refer datatype in ajax

In PHP Script use json_encode function like,

echo json_encode($yourarray);
return;
