代碼實(shí)現(xiàn)

集合wx.setStorageSync()和wx.getStorageSync()這兩個(gè)同步函數(shù)來(lái)實(shí)現(xiàn)這個(gè)功能實(shí)際上非常簡(jiǎn)單。

<!-- wxml --><view class="search-box"> <view class='icon'>  <image src='../../assets/search.png' mode='widthFix'></image>  <!-- 使用bindinput屬性綁定getSearchKey函數(shù)獲取input組件中的值-->  <!-- 使用bindblur屬性綁定routeToSearchResPage函數(shù)處理input失去焦點(diǎn)事件-->  <input placeholder='搜索你想購(gòu)買的商品' bindinput='getSearchKey' bindblur='routeToSearchResPage'></input> </view> <text>取消</text></view><view class='options'> <text>歷史搜索記錄</text> <text bindtap='clearHistory'>清空</text></view><view class='options'><!-- 遍歷 history 數(shù)組 --> <text class='item' wx:for='{{history}}' data-index='{{index}}' bindtap='routeToSearchResPage'>{{item}}</text></view>

JavaScript

//index.jsPage({ data: {  searchKey: "",  history: [] }, //獲取input文本 getSearchKey: function(e) {  this.setData({   searchKey: e.detail.value  }) }, // 清空page對(duì)象data的history數(shù)組 重置緩存為[] clearHistory: function() {  this.setData({   history: []  })  wx.setStorageSync("history", []) }, // input失去焦點(diǎn)函數(shù) routeToSearchResPage: function(e) {  //對(duì)歷史記錄的點(diǎn)擊事件 已忽略  let _this = this;  let _searchKey = this.data.searchKey;  if (!this.data.searchKey) {   return  }  let history = wx.getStorageSync("history") || [];  history.push(this.data.searchKey)  wx.setStorageSync("history", history); }, //每次顯示鉤子函數(shù)都去讀一次本地storage onShow: function() {  this.setData({   history: wx.getStorageSync("history") || []  }) }})
