The JSON respons

Answer 1

Your problem is that you are not parsing the JSON string. Therefore, your foreach is going through the characters in the JSON string.

// If you are using jQuery.ajax, you can just set dataType to 'json' 
// and the following line will be done for you
var obj  = jQuery.parseJSON( response );
// Now the two will work
$.each(obj, function(key, value) {
    alert(key + ' ' + value);
});


for (var key in obj) {
    alert(key + ' ' + response[key]);
}
