原Json数据
- [
- {"id":"4","pid":"1","name":"大家电"},
- {"id":"5","pid":"1","name":"生活电器"},
- {"id":"1","pid":"0","name":"家用电器"},
- {"id":"2","pid":"0","name":"服饰"},
- {"id":"3","pid":"0","name":"化妆"},
- {"id":"7","pid":"4","name":"空调"},
- {"id":"8","pid":"4","name":"冰箱"},
- {"id":"9","pid":"4","name":"洗衣机"},
- {"id":"10","pid":"4","name":"热水器"},
- {"id":"11","pid":"3","name":"面部护理"},
- {"id":"12","pid":"3","name":"口腔护理"},
- {"id":"13","pid":"2","name":"男装"},
- {"id":"14","pid":"2","name":"女装"},
- {"id":"15","pid":"7","name":"海尔空调"},
- {"id":"16","pid":"7","name":"美的空调"},
- {"id":"19","pid":"5","name":"加湿器"},
- {"id":"20","pid":"5","name":"电熨斗"}

转成 Json树状结构
- [
- {"id":"1","pid":"0","name":"家用电器", "chindren":[
- {"id":"4","pid":"1","name":"大家电", "chindren":[
- {"id":"7","pid":"4","name":"空调", "chindren":[
- {"id":"15","pid":"7","name":"海尔空调"},
- {"id":"16","pid":"7","name":"美的空调"}
- ]},
- {"id":"8","pid":"4","name":"冰箱"},
- {"id":"9","pid":"4","name":"洗衣机"},
- {"id":"10","pid":"4","name":"热水器"}
- ]},
- {"id":"5","pid":"1","name":"生活电器","chindren":[
- {"id":"19","pid":"5","name":"加湿器"},
- {"id":"20","pid":"5","name":"电熨斗"}
- ]}
- ]},
- {"id":"2","pid":"0","name":"服饰","chindren":[
- {"id":"13","pid":"2","name":"男装"},

PS:在后台实现转换Json树状结构

你有定义Model吗？在Model里定义好这个关系，并往Children里添加数据，最后，对根对象使用转换Json的方法就达到目的了。

没有定义Model
@Summer丿文: 或者实体对象也没有？
如果这些都没有，要想拼接的话，相对就很难了。
@519740105: 你有实体对象生产Json树状结构的案例吗?
//递归函数，生成树 private IList GetCategoryList(IEnumerable<Category> categories) { var list = new List(); foreach(var category in categories) { var children = null; if(category.Children.Count > 0) { children = GetCategoryList(category.Children); } list.Add( new { id = category.Id, pid = category.Pid, name = category.Name, children = children }; ); } return list; } //调用： var categories = new List<Category>(); var list = GetCategoryList(categories); var json = Json(list);
@Summer丿文:
一样的。
只是实体的属性可能很多，json序列化的时候会多很多内容，可以通过JsonIgnoreAttribute特性忽略。
使用JsonIgnore的时候，需要引用第三方的模块Json。.net本身内置了json序列化，是不一定要引用第三方模块的。
在不想定义Model，又不想引用Json模块（实际上，还需要修改实体）的情状下，你可以：
@519740105: 那在Model中定义还是不是简单一点呢?
@519740105: 那在Model中定义好是不是简单一点呢?
@Summer丿文: 定义Model后，因为强类型（有类定义了，不再是匿名类了），比起这样写，肯定要好点，但如果只是这一个需求，不一定要定义Model。
@519740105: 恩恩,麻烦您了!

1.自己遍历,
2.linq语法,
这个东西就是几个循环的事情..跟第三方插件有什么关系?
新手不太懂!

我不要在前台转的,我不会java,我用的是.net

有没有纯java代码写的
