在获取列表的步骤前，把搜索条件进行判断，判断是否保存了该数据

this.queryParams = this.$store.state.sned.StatMentquery || {}

然后一一把每一项进行赋值

          this.queryParams.globalNumber =this.queryParams.globalNumber || undefined;
          this.queryParams.irNumber =this.queryParams.irNumber || undefined;
          this.queryParams.line =this.queryParams.line || undefined;
          this.queryParams.size =this.queryParams.size || 10;
          this.queryParams.zhuangtai =this.queryParams.zhuangtai || undefined;
          this.queryParams.zuzu =this.queryParams.zuzu || undefined;
          this.queryParams.current =this.queryParams.current || 1;

在接口搜索完，进行保存

this.$store.commit('sned/SET_StatMentquery',this.queryParams)

总体代码

getList(){
          this.queryParams = this.$store.state.sned.StatMentquery || {}
          if(this.queryParams.beginFashengriqi){
            this.daterangeCreateTime = this.queryParams.beginFashengriqi.split(",")
          }
          
          this.loading = true
          this.queryParams.beginFashengriqi = '';
          this.queryParams.endFashengriqi = '';
          if (null != this.daterangeCreateTime && '' != this.daterangeCreateTime) {
            this.queryParams.beginFashengriqi = this.daterangeCreateTime[0] + ',' + this.daterangeCreateTime[1];
            this.queryParams.endFashengriqi = this.daterangeCreateTime[1] + ',' + this.daterangeCreateTime[0];
          }

          this.queryParams.globalNumber =this.queryParams.globalNumber || undefined;
          this.queryParams.irNumber =this.queryParams.irNumber || undefined;
          this.queryParams.line =this.queryParams.line || undefined;
          this.queryParams.size =this.queryParams.size || 10;
          this.queryParams.zhuangtai =this.queryParams.zhuangtai || undefined;
          this.queryParams.zuzu =this.queryParams.zuzu || undefined;
          this.queryParams.current =this.queryParams.current || 1;
          scheduling(this.queryParams).then(res => {
            this.$store.commit('sned/SET_StatMentquery',this.queryParams)
            this.data = res.data.records
           
            this.total = res.data.total
            this.loading = false
          })

        },
