How to access an array in a JSON object?

Question

I have the following JSON object:

    {
        "comments": [
            {
                "created_at": "2011-02-09T14:42:42-08:0         


        

Answer 1

You have to mention the dataType in the ajax request as 'JSON'. Make user you did that like below.

 $.ajax({
            url: $('#frmAddCourse').attr('action'),
            type: 'POST',
            data: $('#frmAddCourse').serialize(),
            dataType: 'JSON',
            success: function (data){
                Materialize.toast(data['state'],2000);
            },
            error:function(){
                Materialize.toast(errorMessage,2000);
            }
        });
