Reactda ichki komponentda holatni tahrirlash

Oldingi darsda olgan Product komponentimizni ko'rib chiqamiz:

jsxfunction Product({ id, name, cost, isEdit, toggleMode, editProd }) {
  return <div>
    name: {
      isEdit
      ? <input value={name} onChange={event => editProd(id, 'name', event)} />
      : <span>{name}</span>
    }
    cost: {
      isEdit
      ? <input value={cost} onChange={event => editProd(id, 'cost', event)} />
      : <span>{cost}</span>
    }
    
    <button onClick={() => toggleMode(id)}>
      {isEdit ? 'save': 'edit'}
    </button>
  </div>;
}

Mahsulot nomi va mahsulot narxi uchun kod deyarli takrorlanganligini osongina payqash mumkin. Keling, ushbu kodni alohida ProductField komponentiga ajratamiz:

jsxfunction ProductField({ id, text, type, isEdit, editProd }) {
  return isEdit
    ? <input value={text} onChange={event => editProd(id, type, event)} />
    : <span>{text}</span>
  ;
}

Product komponentida o'zgartirishlar kiritamiz:

jsxfunction Product({ id, name, cost, isEdit, toggleMode, editProd }) {
  return <div>
    name: <ProductField
      id={id}
      text={name}
      type="name"
      isEdit={isEdit}
      editProd={editProd}
    />,
    
    cost: <ProductField
      id={id}
      text={cost}
      type="cost"
      isEdit={isEdit}
      editProd={editProd}
    />
    
    <button onClick={() => toggleMode(id)}>
      {isEdit ? 'save': 'edit'}
    </button>
  </div>;
}
