  Hi Daniel,

  So the problem with using data = is that you are only assigning the local variable that way - it doesn't effect what the original variable that Editor holds points to (it isn't a pointer like in C or C++).

  What you need to do is modify the object that is passed in, which is why the data.data = works.

  So you'd need to do something like:

  data.value = ...
  data.timestamp = ...
  

  Or:

  $.extend( data, {
    value: ...,
    timestamp: ...
  } );
  

  If you want to remove the properties Editor adds to the object, you'd need to delete them - e.g. delete data.action;.

  Hi Allan,

  thanks for the fast response.
  Now I can manipulate the values, which should be part of the payload. That's working :)

  But i'm still not able to use my own string-representation.
  Everything is interpreted like URL parameters (escaped data, using ? to concatenate parameters, ... )

  My goal is to send a clear JSON object.
  Here is an example:

      editor.on('preSubmit', function(event, data, action) {
          data.value = 12;
          data.timestamp = "2015-11-20 11:35:03.540351+01:00";
          delete data.action;
          delete data.data;  // Deletes everything, which was added by editor form
          console.log(JSON.stringify(data));
  

  The console output would be:

  {"value":12,"timestamp":"2015-11-20 11:35:03.540351+01:00"}
  

  And exact this is the string, which needs to be send to the server (without any manipulation) :-)

  Is this somehow possible?

  Another approach would be to use my own ajax-call and prohibit the editor to send its own one.
  Do you think is is possible?

  Thanks for the help,
  Daniel

  Hi Daniel,

  Just to confirm - you want to send a JSON string in the POST request's body? That absolutely can be done, but we need to use ajax.data for that (rather than preSubmit).

  Have a look at the last example on the ajax.data page - it shows exactly what you are looking for.

  Hi Allan,

  you are right. I don't know how I could miss this piece of documentation.
  Everything is working now. Thanks for the great support.

  For everyone else reading this topic, this is my final configuration:

  var editor = new $.fn.dataTable.Editor( {
      ajax:  {
          url: 'http://my-company.com/api/entry',
          contentType: 'application/json',
          data: function ( d ) {
              var ownData = {value: d.data[0]["value"], timestamp: d.data[0]["timestamp"]}
  
              return JSON.stringify( ownData );
          }
      },
      table: '#my-table',
      fields: [ {
              label: "Timestamp:",
              name: "timestamp"
              }, {
              label: "Value:",
              name: "value"
              }]
      } );
