'Ajax calls content type

I have a question regarding to ajax,

I have something like:

ajax({
  type: 'post',
  data: {
    'mode': 'update',
    'data': JSON.stringify(jsonData)
  },
  url: '...',
  dataType: 'JSON', 
  success: function(res) {
    //...
  },
  error: function(res) {
    //...
  }
});

But I do not use contentType, but my request actually contain JSON and one extra info of 'mode', should I add some information here for contentType, I tested my calls, they are working without issues, but I would like to know if there is any issues with this call.

any help would be much appreciated.

The issue is that your entire data object is not stringified..

try...


var data = {
    mode : 'update',
    data : jsonData
}

$.ajax({
    type: 'post',
    data: JSON.stringify(data),
    url: '...',
    contentType: 'application\json',
    success: function(res){...},
    error: function(res){...}
});

//also might want to try and use the short hand version for post
$.post(url, JSON.stringify(data))
    .done(function(res) { /**/ })
    .fail(function(res) { /**/ });

This solution stringifies the entire data object not just the one property.
