微信小程序收藏功能的实现代码

<image class="save " src="{{isClick?'../../youzan-image/save-s.png':'../../youzan-image/save.png'}}" bindtap="haveSave"></image>   <text class="saveText">{{isClick?'已收藏':'收藏'}}</text>

 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, }) },})
