如何输出此json文件的特定图层。我有一个页面，我只需要分支，另一个页面，我只需要分支的分类。然后更深入一页，我只需要一个类别或分支的子类别。在最深的页面，我只需要一个类别的产品。

是否有一种简单的方法可以解析这个json文件并访问它＆＃34;＆＃34;层＆＃34;根据需要？

Answer 1

// parse json to object
var obj = JSON.parse(yourJSON);
// deep copy the part of the object that you need
var categories = jQuery.extend({}, obj.categories);
// make a json out of it, if that's what you need
var categoriesJSON = JSON.stringify(categories);

最后一步是如果你真的需要它作为JSON，但我想情况并非如此，你可以在你的页面上使用categories对象。

使用jquery输出特定的json文件层
