Computed property was assigned to but it has no setter问题解决

提示此问题，是因为在computed 里面定义的属性 只有一个return返回。因为在其他地方进行了赋值操作，导致提示此错误！如下代码所示：

更改之前的代码：

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

解决办法：修改成如下的代码：

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