Why getting NULL even JSON Array exist in response of jQuery.ajax?

Question

Basically response consist of two things JSON Array and isValid(flag)

I can get flag value successful But it gives the null var resJSON = jQuery.parseJSON(data.notification);. I debug my script in chrome console but json response exist in data.

Might be following code and console result help you to understand my problem!

function getNotificationById(notificationId) {
    jQuery.ajax({
        type: "POST",
        url: "<%=request.getContextPath()%>/GetNotifications/",
        dataType : "json",
        data: {"operation": "getNotificationById", "notificationId": notificationId},

        success:function(data){ 

            var resJSON = jQuery.parseJSON(data.notification);
             //   ^-- here is null  

            if (data.isValid) {
            //    ^-- response is true          
                jQuery.each(resJSON,function(i, value){
                    console.log(value.Body);
                });
            }
        }
    });
}

Chrome Console Result:

Edit I have tried following solutions:

var resJSON = data.notification;  // Chrome Console return **undefined**

try var resJSON = data.notification;. I think you are trying to parse an object instead of string — Cerlin

Since you have set dataType: 'json', data.notification will be an object.. so no need to parse it agaibn — Arun P Johny

@Cerlin I have tried it gives "resJSON = undefined," in console — mumair

console log the object and see if the property exists or not. like console.log(data); or console.dir(data); — Cerlin

You have a typo. The data as shown in traces are included in data.notificaiton and not data.notification
