当你使用Vuex中state中状态时，在Vue中使用了v-model绑定数据报错

Computed property “XXX” was assigned to but it has no setter错误_数据双向绑定

 

Computed property “XXX” was assigned to but it has no setter错误_Vuex_02

Computed property “XXX” was assigned to but it has no setter错误_bug_03

 原因

  1. 组件中v-model=“XXX”，而XXX是vuex state中的某个变量
  2. vuex中是单项流，v-model是vue中的双向绑定，但是在computed中只通过get获取参数值，没有set无法改变参数值

解决

在computed中添加get和set

Computed property “XXX” was assigned to but it has no setter错误_vue_04

将v-model改成:value
