今天做搜索页面遇到了搜索记录,那如何把纪律在刷新页面的情况下还存在呢
这俩介绍一种同步的微信小程序请求数据的写法
存储:
wx.setStorageSync(‘list’, ll)
语法
wx.setStorageSync(‘存储的名’, 存储的值)
读取:
wx.getStorageSync(‘list’)
语法
wx.getStorageSync(‘存储的名’)
如果存储在本地,想一刷新页面的时候我们直接获取到数据可以这样写一下
* 生命周期函数--监听页面加载 */ onLoad: function (options) { var
list=wx.getStorageSync('list') console.log(list) if(list) { this.setData({
lishi:list }) } wx.request({ url: ' *******************************************
', header: { 'content-type': 'application/json' // 默认值 }, success:((res)=>{
//console.log(res) this.setData({ list:res.data.list }) }) }) },
在页面加载这个生命周期中
判断本地是否有数据
如果有的话直接setData让他提前的加载到data数据中
就可以提前的渲染出来了
