从本地存储和VueX中删除项目

Question

首先，我创建了一个配方，并通过将配方添加到“状态”矩阵中使用本地存储和VueX存储了该配方 该项目将显示一组可以删除配方的配方。 如图所示。 如何从本地存储和VueX中删除配方？

store.js：

import Vue from 'vue'
import Vuex from 'vuex'
import image1 from '../assets/img/image4.jpg'
import image2 from '../assets/img/image2.jpg'
import image3 from '../assets/img/image3.jpg'
import image4 from '../assets/img/insta2.jpg'
Vue.use(Vuex)
export const store = new Vuex.Store({
    state:{
        loadedRecipes:[
            {imageUrl:image3,
                id:'3' , title:'Homemade Burger',
                description:'Small plates, salads & sandwiches - an intimate setting with 12 indoor 
                           seats plus patio seating..',
                ingredients: '25 Eges 30kg Water'
            },
            {imageUrl:image1,
                id:'1' , title:'Cake',
                description:'Small plates, salads & sandwiches - an intimate setting with 12 indoor 
                       seats plus patio seating..',
                ingredients: '25 Eges 30kg Water'
            },
            {imageUrl:image4,
                id:'4' , title:'Salad',
                description:'Small plates, salads & sandwiches - an intimate setting with 12 indoor 
                        seats plus patio seating..',
                ingredients: '25 Eges 30kg Water'
            },
            {imageUrl:image2,id:'2' ,
             title:'Kabseh',description:'Small plates, salads & sandwiches - an intimate setting with 
                12 indoor seats plus patio seating.',
             ingredients: '25 Eges 30kg Water'
            }
    
          ],
          user:{
              id:'nvdcjavdah',
              registeredRecipes:['jhvjhvmnbvhj']
          }
    },
   mutations:{
        createRecipe(state,payload){
            Vue.set(state, 'loadedRecipes', [...state.loadedRecipes, payload])
            state.loadedRecipes.push(payload)
        }
    },
    actions:{
        // createRecipe(payload){
        //     const recipe = {
        //         title : payload.title,
        //         imageUrl: payload.imageUrl,
        //         description:payload.description,
        //         ingredients:payload.ingredients,
        //         id:'hgxckjh'
        //     }
        //     console.log(recipe)
        // }
    },
    getters:{
        loadedRecipes(state){
            return state.loadedRecipes.sort((RecipeA,RecipeB)=>{
                return RecipeA.id >RecipeB.id
            })
        },
        featuredRecipes(state,getters){
            return getters.loadedRecipes.slice(0,5)
        },
        loadedRecipe(state){
            return (recipeId)=>{
                return state.loadedRecipes.find((recipe)=>{
                    return recipe.id === recipeId
                })
            }
        }
    }
})

Recipes.vue： 此代码用于显示所有食谱：

  <v-container>
    <v-layout row wrap v-for="recipe in Recipes" :key="recipe.id" class="mb-2">

创建动作；

    deleteRecipe({commit}, id) {            
          commit('delete_recipe', id)
      }
     

突变时；

delete_recipe(state, id){
 index = state.loadedRecipes.findIndex(recipe => recipe.id == id)
 state.loadedRecipes.splice(index, 1)
}
