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);
},
~~~
