`post.js`
~~~javascript
onPostTap:function(event){
var postId = event.currentTarget.dataset.postid;
console.log(postId);
wx.navigateTo({
url: 'post-detail/post-detail?id='+postId,
})
},
~~~
`post-detail.js`
~~~javascript
onLoad: function (options) {
var postId = options.id;
// var postData = postsData.postList[postId];
//console.log(postData);
//this.setData(postData);
},

detail: "菊黃蟹正肥，品嘗秋之味。徐志摩把“看初花的荻蘆”和“到樓外樓吃蟹”并列為秋天來杭州不能錯過的風雅之事；用林妹妹的話講是“螯封嫩玉雙雙滿，殼凸紅脂塊塊香”；在《世說新語》里，晉畢卓更是感嘆“右手持酒杯，左手持蟹螯，拍浮酒船中，便足了一生矣。”漫漫人生長路，美食與愛豈可辜負？于是作為一個吃貨，突然也很想回味一下屬于我的味蕾記憶。記憶中的秋蟹，是家人的味道，彌漫著濃濃的親情。\n\n是誰來自山川湖海，卻囿于晝夜，廚房與愛？ 是母親，深思熟慮，聰明耐心。吃蟹前，總會拿出幾件工具，煞有介事而樂此不疲。告訴我們螃蟹至寒，需要佐以姜茶以祛寒，在配備的米醋小碟里，亦添入姜絲與紫蘇，前者驅寒后者增香。泡好菊花茶，歲月靜好，我們靜等。",
