A huļi?

Izvadi pirms tās nestrādājošās rindas console.log(JSON.stringify(this.state.r), JSON.stringify(k.id))

[{"ID":"18","item_id":"2","item_amount_stock":"5","item_amount_in_cart":"0","item_amount_preordered":"0","item_amount_sold":"0","item_timestamp":"2015-07-22 12:30:59","last_edit_timestamp":"2015-07-22 12:30:59","item_id_catalog":"prod2","item_name_catalog":"Spilvens","item_measurement_unit":"pcs"},{"ID":"12","item_id":"4","item_amount_stock":"25","item_amount_in_cart":"0","item_amount_preordered":"0","item_amount_sold":"0","item_timestamp":"2015-07-22 10:01:15","last_edit_timestamp":"2015-07-22 11:54:05","item_id_catalog":"prod3","item_name_catalog":"Desa","item_measurement_unit":"kg"}]

JSON.parse(JSON.stringify(this.state.ri[0])) <-- NESTRADĀ "SyntaxError: JSON.parse: unexpected character at line 1 column 1 of the JSON data"

 

JSON.stringify(this.state.ri[0]) <-- Strādā.

 

Nu wtf :)

Nezinu kā tas REACT tur darās, bet gan jau this konteksts pazūd...

                        for (var i = 0; i < json[1].output.length; i++) {
                            json[1].output[i].edit = function() { 
                                console.log(json[1].output.ID);
                                this.props.handleMenu(this,'functions',new Event('post')); 
                            }.bind(this);
                        }

Atkal tas pats, json[1].output.ID eksistē, bet atgriezt nevar. Varbūt kāds izpalīdzēs?
