var postsData=require(’…/…/…/data/post-data.js’)
Page({
date:{

},

onLoad:function(option){
var postId=option.id;

this.data.currentPostId=postId;
var postData=postsData.postList[postId];
//this.data.currentPostId=postId;
this.setData({
postData:postData,
currentPostId:postId
});

var postsCollected=wx.getStorageSync(‘posts_collected’);
if(postsCollected){
var postColllected=postsCollected[postId];
if(postCollected){
this.setData({
collected:postCollected
})
}
}
else{
var postsCollected = {};
postsCollected[postId]=false;
wx.setStorageSync(‘posts_collected’, postsCollected);

}
},

onCollectionTap:function(event){
var postsCollected=wx.getStorageSync(‘posts_collected’);
var postCollected=postsCollected[this.data.currentPostId];
postCollected=!postCollected;
postsCollected[this.data.currentPostId]=postCollected;
wx.setStorageSync(‘posts_collected’, postsCollected);

this.setData({
  collected: postCollected
})

}

})

这段代码第一遍点进去是正确的，第二次进去后就出现错误，也按老师的做法添加了 if(postCollected){}，但错误依然。

postCollected is not defined ReferenceError: postCollected is not defined
