這是我將按 orderId 過濾然后設(shè)置為狀態(tài)變量的 JSON 輸入。[{"orderId":3,"userId":3,"firstName":"Amal","lastName":"kankanige","contactNo":"011-3456787","status":"pending","deliveryAddress":"No:24/c,Anders Road,Wijerama,Wijerama,Srilanka","productName":"Apple","quantity":2,"total":100.0,"id":null,"order_date":"2019-01-31 10:28:29"}]這是我的狀態(tài)。  this.state = {      merchentOrders: [],      filterMerchentOrders: []    }//這是方法當(dāng)我按 orderId 過濾時，它成功運(yùn)行，然后我想將過濾后的輸出設(shè)置為“ this.setState({filterMerchentOrders: filterMerchentOrdersX});”。當(dāng)我調(diào)出如下狀態(tài)時，未設(shè)置值。getOrderDetails = id => {    console.log("id ==" ,id);    let filterMerchentOrdersX = this.state.merchentOrders.filter(value => {      return (        value.orderId.toString()          .indexOf(id) !== -1      );    });             this.setState({filterMerchentOrders: filterMerchentOrdersX});   //this is working       console.log("filterMerchentOrdersX ==" ,filterMerchentOrdersX);          //this gives an empty array        console.log("this.state.filterMerchentOrders ==" ,this.state.filterMerchentOrders);  };
