自己刚接触小程序，在网上找了很多的收藏的代码，但是发现都点击收藏后，退出去再回来已收藏又变成未收藏状态，然后自己就改改改 拼拼凑凑终于改了出来 侵删就是代码有些复杂 感觉可以更简便 但是我还没有找到方法 在这里记录一下 有大佬也可以指点一下
.wxml代码
<viewclass="save"><textclass="saveText">{{isClick?'已收藏':'收藏'}}</text><imagestyle="height:50rpx;padding:4rpx;"mode="heightFix"src="{{isClick?'https://636c-cloud1-2gz5yzstf4bf5a3e-1309497881.tcb.qcloud.la/%E8%81%9A%E6%94%B6%E8%97%8Fgift.png?sign=f791e9c1b27556e4edbfb9dab7ae8fa8&t=1649143160':'https://636c-cloud1-2gz5yzstf4bf5a3e-1309497881.tcb.qcloud.la/%E8%81%9A%E6%94%B6%E8%97%8F%20(1).png?sign=06b33d1e2e959ece67f398aac815b110&t=1649143139'}}"bindtap="haveSave"></image></view>
.js代码
data:{job:[],job2:[],id:'',isClick:false,jobStorage:[],jobId:''},haveSave(e){letjobData=this.data.jobStorage;lettruejobDat=this.data.job2;this.setData({job2:wx.getStorageSync('jobData')})for(vari=0;i<(this.data.job2.length);i++){if(this.data.job2[i].saved==true){jobData.push({jobid:this.data.job2[i].jobid,id:this.data.job2[i].id,saved:this.data.job2[i].saved})}}if(!this.data.isClick==true){jobData.push({jobid:jobData.length,id:this.data.id,saved:true})wx.setStorageSync('jobData',jobData);//设置缓存wx.showToast({title:'已收藏',});}else{console.log(jobData)for(vari=0;i<(jobData.length);i++){if(jobData[i].id!=this.options.index){truejobDat.push({jobid:jobData[i].jobid,id:jobData[i].id,saved:jobData[i].saved})}}wx.showToast({title:'已取消收藏',});wx.setStorageSync('jobData',truejobDat);}this.setData({isClick:!this.data.isClick})},onLoad:function(options){letdetailStorage=wx.getStorageSync('jobData')console.log(wx.getStorageSync('jobData'))for(vari=0;i<(detailStorage.length);i++){if(detailStorage[i].id==options.index){if(detailStorage[i].saved){this.setData({isClick:true})}}}}，
结果：
