Cómo realizar la operación de propagación en el objeto de matriz de usuario de ventas. necesita agregar ..salesusertargetAmount:500, en ese objeto
{ "station": [ { "stationname":"chennai", "stationtargetAmount":500, "salesusers":[ { " salesusersname":"tester", }, ] }, { "stationname":"chennai22222", "stationtargetAmount":500, "salesusers":[ { " salesusersname":"tester222222", }, ] } ] }probado con
let salesusertargetamt = "100" this.setState({ salesusers: this.state.station.map((items) => { items.salesusers.map(el => (el.salesusersname !== "" ? { ...el, salesusertargetamt } : el)) });let salesusertargetamt = "100" this.setState({ salesusers: this.state.station.map((items) => { return items.salesusers.map(el => (el.salesusersname !== "" ? { ...el, stationtargetAmount: salesusertargetamt } : el)) });Las llaves ( { ) son complicadas aquí porque ambas significan bloque de código y objeto JavaScript, por lo que debe envolverlas con () :
let salesusertargetamt = "100"; let obj = { "station": [ { "stationname":"chennai", "stationtargetAmount":500, "salesusers":[ { " salesusersname":"tester", }, ] }, { "stationname":"chennai22222", "stationtargetAmount":500, "salesusers":[ { " salesusersname":"tester222222", }, ] } ] }; let result = obj.station.map(items => ({ ...items, salesusers: items.salesusers.map(user => (user.salesusersname !== "" ? {...user, salesusertargetamt} : user )) })) console.log(result);
