写过的bug

const actions={
  updateUsername: ( { commit},value )=>{
    console.log("actions updateUsername");
    commit('updateUsername',value)
  }
}

不能这样写{commit,value}


props传boolean   要用单引号

componen-title='false'
双引号会报错  Invalid prop: type check failed for prop "componenTitle". Expected Boolean, got String.

...mapActions传值

Vue组件

<input @keyup.enter="renovateName(listName)" type="text" v-model="input"  placeholder="updateUsername" />

methods:{
　　...mapActions(['updateUsername']),
　　renovateName:function(x){
   　　this.updateUsername(x).then((data)=>{
    　 　　console.log("Promise resolve:");
       　　console.log(data)
   　　})
　　}
}

store/index.js


const actions={
  updateUsername: ( { commit},value )=>{
    console.log("actions updateUsername");
    console.log(value);

    return new Promise((resolve, reject) => {
      setTimeout(() => {
        commit('updateUsername',value);


        resolve("2131231")

      }, 1000)

    })

  }
}
