any hints / helps / suggestions mean lot me.

  1. .prop('disabled', true); believe typo or something, disable every options.

  2. the true, false value in jsonobj may string. so, no matter value 'true' or 'false', treaded true, !reportable false, means won't disable option.

you may have check if string first, :

reportable = (typeof v.reportable === 'string') ? v.reportable === 'true' : v.reportable

to convert boolean first.

var reportable = [    {userid: 's-00591', reportable: 'true'},    {userid: 's-00592', reportable: 'false'},    {userid: 's-00593', reportable: 'false'},    {userid: 's-00594', reportable: 'false'},    {userid: 's-00595', reportable: 'false'}  ];    // check diff between string , boolean.  var reportable2 = [    {userid: 's-00591', reportable:  true},    {userid: 's-00592', reportable: false},    {userid: 's-00593', reportable: false},    {userid: 's-00594', reportable: false},    {userid: 's-00595', reportable: false}  ];        $.each(reportable , function(i, v) {    var userid = v.userid;    var reportable = v.reportable;    var currentval = userid;      console.log('start');    console.log(userid + " | " +reportable);    $('#rn-dd option[value="' + currentval + '"]').prop('disabled', !reportable);    console.log('end');    });    $.each(reportable2 , function(i, v) {    var userid = v.userid;    var reportable = v.reportable;    var currentval = userid;      console.log('start');    console.log(userid + " | " +reportable);    $('#rn-dd2 option[value="' + currentval + '"]').prop('disabled', !reportable);    console.log('end');    });
