Computed property was assigned to but it has no setter問題解決

Computed property was assigned to but it has no setter問題解決

提示此問題，是因為在computed 里面定義的屬性 只有一個return返回。因為在其他地方進行了賦值操作，導致提示此錯誤！如下代碼所示：

更改之前的代碼：

 computed: {
            drCountData() {
                return this.$store.state.drCountData;
            },
        },

   
   
   
           

  
  
  
          

解決辦法：修改成如下的代碼：

computed: {
            drCountData: {
                get(){
                    return this.$store.state.drCountData;
                },
                set(v) {
                    this.countData = v
                }
            },
