Question

我正在尝试解构以下功能：

import { CHANGE_MSG, INCREMENT_COUNTER } from './mutation_types'

export const changeMessage = (store, msg) => {
  store.commit(CHANGE_MSG, msg)
}

这样：

// ES2015 arguments destructuring
changeMessage ({ commit }, msg) {
  commit (CHANGE_MSG, msg)
}

但是，'{'

会引发错误

Parsing error: unexpected token , [js] expected ;

我的编码出了什么问题？感谢您的反馈

剪切和粘贴问题，忘记编写导出语句它以这种方式运行：

import { CHANGE_MSG, INCREMENT_COUNTER } from './mutation_types'

export default {
  changeMessage ({ commit }, msg) {
    commit(CHANGE_MSG, msg)
  },
  incrementCounter ({ commit }) {
    commit(INCREMENT_COUNTER)
  }

}

ES2015论证解构错误
