微信小程序中不同页面间的参数传递

1 <!--此为样式页面-->
2 <block wx:for="{{postList}}" wx:for-item="item" wx:for-index="idx">
3     <view catchtap="onPostTap" data-postid="{{item.postId}}">
4         <template is="postItem" data="{{...item}}"/>
5     </view>
6 </block>    

1 //此为逻辑层代码
2 onPostTap: function (event){
3     var postId = event.currentTarget.dataset.postid;
4     wx.navigateTo({
5         url: "post-detail/post-detail?id=" + postId;
6     })
7 }

1 //需要传递的参数名为postId
2 wx.navigateTo({
3     url: "post-detail/post-detail?id=" + postId
4 })

1 //另一页面接收参数
2 onLoad: function (option) {
3     var postId = option.id;
4 }
