如何使用Vuex更新数组内的对象？我试过这个,但它不起作用:

const state = {
  categories: []
};

// mutations:
[mutationType.UPDATE_CATEGORY] (state, id, category) {
  const record = state.categories.find(element => element.id === id);
  state.categories[record] = category;
}

// actions:
updateCategory({commit}, id, category) {
  categoriesApi.updateCategory(id, category).then((response) => {
    commit(mutationType.UPDATE_CATEGORY, id, response);
    router.push({name: 'categories'});
  })
}
