				  gui_bin 2018-10-05 //显示收藏 未收藏 var postsCollected = wx.getStorageSync("posts_collected"); if (postsCollected === ""){//需要补上这个的判断 postsCollected = {}; } if(postsCollected){ var postIsCollected = postsCollected[detailId]; if (postIsCollected){ this.setData({ collected: postIsCollected, }) }else{ // var postsCollected = {}; postsCollected[detailId] = false; wx.setStorageSync("posts_collected", postsCollected); } } 这么写试试,目测完美解决 00
