JSON文件并非都存在于Jquery ajax请求中

I have a problem sending my JSON file parameters through HTTP POST method. The file is properly generated but only part of it is sent.

       $("#catalogOfService").jqGrid('navGrid',"#catalogOfService_pager").jqGrid('navButtonAdd', '#catalogOfService_pager', {
        caption: "Export to Excel",
        onClickButton: function () {
            var json = $("#catalogOfService").getRowData();
            var name = "report_catalogue";
            console.log(json);

            $.ajax({
                type: "POST",
                async: false,
                url: "ExportCatalogueExcell.php",
                data: {
                          name: name, 
                          data: json,
                },

                success: function(result)
                {
                },
                success: function(e){
                    setTimeout(function() {
                        console.log(yeah);
                        window.open("../tmp/" + name + '.csv');
                    }, 1000);
                }
            });
        }
    });

You may need to update this part:

data: JSON.stringify(json)

JSON.stringify() converts a JavaScript value to a JSON string, in other words, it converts a JavaScript object to JSON text and stores that JSON text in a string. And, this JSON text is what you need as the data in your POST request.
