              <span class="cart-list-delet" @click="del(v.goods_id)">刪除</span>
              <input type="checkbox" name="goods" :checked="v.select==true"  @change="toggleSelect(v.goods_id)">

  </div>

</div>

<script>

toggleSelect(id){
      var i=this.findPosition(id);
      var select=this.goodsList[i].select;
      this.updatedGoods({
          index:i,
          key:"select",
          value:!select   //這里切換false和true
      })
  }

</script>

vuex code

import Vue from 'vue'
import Vuex from 'vuex'
Vue.use(Vuex)

export default new Vuex.Store({

state:{
    goodsList:localStorage["goodsList"]?JSON.parse(localStorage["goodsList"]):[]
},
getters:{
    sum:state=>{
        var total=0;
        state.goodsList.forEach((item)=>{
            if(item.select){
                total=(Number(total)+Number(item.price*item.number)+Number(item.freight)).toFixed(2)
            }
        })
        return total
    },
    gooddsNumber:state=>{
        return state.goodsList.length
    }
 },
mutations:{
    getData(state,val){
        state.goodsList.push(val);
        localStorage.setItem("goodsList",JSON.stringify(state.goodsList))
    },
    deleteGoods(state,index){
        state.goodsList.splice(index,1);
        localStorage.setItem("goodsList",JSON.stringify(state.goodsList))
    },
    updatedGoods(state,data){
        const {index,key,value}=data;
        if(state.goodsList[index].inventory>=value){
            state.goodsList[index][key]=value;
        }else{
            alert("庫存不足")
        }
        localStorage.setItem("goodsList",JSON.stringify(state.goodsList))
    }
},
actions:{
    
},

})

這個是之前放在getter中 把它存進本地存儲
顯示為空
