i want access array in j-query returned php script via ajax call

ajax call getting result 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 in pending group");                  $('#meter_group_name').attr('selectedindex',0);                    }               $("select#meter_number").html(data["option"]);             }     });

response of ajax call 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 option field store 

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

how check data["exists"]==1 in jquery code , populate select in html data["option"]?

you can use json_encode() here like,

in js ajax function

add type: 

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

refer datatype in ajax

in php script use json_encode function like,

echo json_encode($yourarray); return;

asp.net mvc - breakpoint on javascript in CSHTML? -

i have .cshtml file has javascript tag. within script tag have few lines of javascript. first line of javascript refers property in @viewbag. other javascript lines plain script without mvc related references. observation: can place breakpoints (visual studio 2015) on each of these javascript lines. however, breakpoints has white dot in center of breakpoint symbol (red circle) except line @viewbag reference (this particular line not have white dot in center). it seems breakpoint without white dot hit during run-time. question: can explain going on here? white dot mean? why plain red breakpoint line line hitting breakpoint? the visual studio debugger expecting debug actual server-side code within .cshtml file opposed client-side javascript within it. iirc, visual studio allow debug javascript code expected in internet explorer (and possibly edge), other browsers want use either third-party tool or developer tools (f12) within browser. an easy approach take advant...
