I have the following ajax call used in different situation:

$.ajax({
  url: '...',
  type: "POST"
  data: {val: '1', test: 'test1' },
  ...
});

I want, for every ajax start and for "POST" method only, to add a parameter to data property.

I used this:

$(document).ajaxStart(function(){
    //if type is POST then
    // data.myProp = 1;  or similar
});

How to get data and type from ajaxStart ?

EDIT

If I use ajax.preFilter then will not work fine.

So:

$.ajaxPrefilter(function(options, originalOptions, jqXHR) {
    if (originalOptions.type === 'POST' || options.type === 'POST') {
        options.data = $.extend(originalOptions.data, { myProp : 1});
    }

});

and then:

$.ajax({
    ...,
    data: { myItem: 'tes' },
    ...
});

then data will not contain myProp because $.ajax declaration will override data over data from ajax.preFilter

I want to have both myProp and myItem parameters to be send to somewhere on server.

You can use ajaxPrefilter : 

$.ajaxPrefilter(function(options, originalOptions, jqXHR) {
    if (originalOptions.type === 'POST' || options.type === 'POST') {
        options.data = $.extend(originalOptions.data, { myProp : 1});
    }

});
