Question

I have an AJAX callback which is supposed to return an entry value for each row in an array

$.ajax({
    url: url,
    datatype: JSON,
    success: function(data){
        $.each(data, function (key, value){
            alert(key + ': ' + value);
        });
    },
    error: function(){
        alert('There was an error loading your request.  <br />Please try again later.');
    }
});

Instead of doing an alert() for each entry, it’s doing an alert() for everything single character in the array. It’s as if it’s drilling down one dimension too far.

Answer 1

That means your date is not being converted into json, it’s looping over the characters in the response string. Verify that data is what you think it is.

I suspect datatype needs to be dataType, and the value for that parameter needs to be “json”
