vue中,在本地缓存中读写数据的方法_vue.js

cnpm i good-storage --save

import storage from 'good-storage'const SEARCH_KEY = '__search__'const SEARCH_MAX_LENGTH = 15// compare:findindex传入的是function,所以不能直接传valfunction insertArray(arr, val, compare, maxLen) { const index = arr.findIndex(compare) if (index === 0) { return } if (index > 0) { arr.splice(index, 1) } arr.unshift(val) // 插入到数组最前 if (maxLen && arr.length > maxLen) { arr.pop() // 删除末位元素 }}// 存储搜索历史export function saveSearch(query) { let searches = storage.get(SEARCH_KEY, []) insertArray(searches, query, (item) => { return item === query }, SEARCH_MAX_LENGTH) storage.set(SEARCH_KEY, searches) return searches}// 加载本地缓存的搜索历史export function loadSearch() { return storage.get(SEARCH_KEY, [])}

import * as types from './mutation-types'import {saveSearch} from 'common/js/cache'export const saveSearchHistory = function({commit, state}, query) { commit(types.SET_SEARCH_HISTORY, saveSearch(query))}

import {mapActions} from 'vuex'// methods内: saveSearch() {  this.saveSearchHistory(this.query) }, ...mapActions([  'saveSearchHistory' ])
