Реагировать на спецификацию редактирования c элемент

Question

Когда я нажимаю кнопку «Редактировать», я запускаю флаг для включения редактирования. Желаемым поведением будет включение редактирования только для одного элемента за раз. Однако все элементы включаются для редактирования под флагом.

<li key={recipe._id} className="list__item recipe" id={randomString()}>

Answer 1

Вы не передали свой полный код, но он должен выглядеть примерно так:

state = {
    editableId:null
}

editRecipe = (event,recipe) => {
    this.setState(({editableId:recipe._id}))
}

<Button disabled={!this.state.editableId == recipe._id} color="primary" onClick={(e) => { editRecipe(e, recipe); }} id={`card-${recipe._id}`} className={'edit-button'}>Edit</Button>

Если вы не хотите, чтобы элементы редактировались, сбросьте state.editableId на ноль
