properly encode and decode json results (php to js)

Question

I am trying to encode my array results to json and pass them to a ajax successful event in javascript.

PHP

    $results = array(
        "time1" => 1,
        "time2" => 2,

    );
    echo json_encode($results);

JAVASCRIPT / JQUERY

   $.ajax({
             type: "POST",
             url: "actions/myphp.php",
             data: PassArray,
             dataType: 'json',
             beforeSend: function (html) { // this happens before actual call
             //    alert(html);
             },
             success: function (html) { 
                 // $("#loginoutcome").text(html);
                // alert(html);
                 var obj  = jQuery.parseJSON(html ); 
                // Now the two will work
                $.each(obj, function(key, value) {
                    alert(key + ' ' + value);
                });

             },

Leaving the JQUERY.parseJSON there throws a json parse unexpected character, I dont think I that I need it anyway as I specify in the dataType: 'json', above?.. But how can I retrieve the values ??

Thanks

As you pass datatype as JSON, jQuery will give you back the JSON object, you don't have to parse it anymore.

So make it like this:

success: function (obj) { 
            $.each(obj, function(key, value) {
                alert(key + ' ' + value);
            });

         },

If you know its time1 or time2, you can do this:

success: function (obj) { 
            alert(obj.time1);
            alert(obj.time2);
         },
