微信小程序收藏功能的实现代码

   {{isClick&＃63;'已收藏':'收藏'}}

 Page({
  data: {
  job: [],
  jobList: [],
  id: '',
  isClick: false,
  jobStorage: [],
  jobId: ''
  },
  haveSave(e) {
  if (!this.data.isClick == true) {
   let jobData = this.data.jobStorage;
   jobData.push({
   jobid: jobData.length,
   id: this.data.job.id
   })
   wx.setStorageSync('jobData', jobData);//设置缓存
   wx.showToast({
   title: '已收藏',
   });
  } else {
   wx.showToast({
   title: '已取消收藏',
   });
  }
  this.setData({
   isClick: !this.data.isClick
  })
  }
 })

import jobList from '../../api/detail'
Page({
 data: {
 id:'',
 job:[],
 savejob:[],
 },
 onLoad: function (options) {
 console.log(wx.getStorageSync('jobData'));
 let savejob = wx.getStorageSync('jobData')//获得缓存
 let index = savejob.length-1;
 console.log(savejob[index].id);
 let jobid = savejob[index].id
 let temp= jobList[jobid] //将获得缓存后匹配的数据放入新的数组
 let job= [];
 job.push(temp);
 this.setData({
  id:index,
  job: job,
 })
 },
})
