I have a module on my Cms that works very well with the jquery 1.7.1 but not works (nothing happens when i click on the button) with the jquery 2.1.1.
I send you the code below :

    $.ajax({
        url: 'index.php?route=checkout/shipping_method/givemr&ismr=1',
        type: 'post',
        data: $('#mr_cp_search, #mr_pays_search'),
        dataType: 'json',   
        success: function(json) {
   
            $('.warning').remove();
           
            if (json['redirect']) {
                location = json['redirect'];
            }
           
            if (json['output']) {
                $('#resultats_pt_relais').html(json['output']);               
            }
        }
    });    

I am not good at jquery so can you tell me if something has changed between the 2 versions.
Thanks for your help.
