按数据库表中的字段过滤

有人请帮助我理解如何从表格中响应的数据创建新对象。我需要通过已经由另一个字段分组的字段构建过滤器。例如，数据已经按类别字段分组，现在对于每个类别，我需要显示它具有的文档文件的类型。我还需要构建一个函数来调用此字段或索引点击吗？ 我得到了以下结构但不知道它是如何工作的，目前它是由不同的字段过滤： 我尝试过： < ling在typeObj中重复输入[category.category] ​​.subcategories ng-click =show（subcategory，category）> typeObj： 类别：{[类别：{a}，类别：{b}，类别：{c}} ... $ scope.show（子类别，类别）{ $ scope.listOfDocuments = $ scope.typeObj（subcategory，id）;}

Does somebody please help me understand how a new object can be created from data responded from a table. I need to build a filter by a field that is already grouped by another one. For example, the data is already grouped by the "category" field and now for each category I need to show the "types" of document files it has. I will also need to build a function to call on click by this field or index? I got the following structure but do not how it is working, currently it is filtering by a different field: What I have tried: <li ng repeat type in typeObj[category.category].subcategories ng-click="show(subcategory, category)> typeObj: categories:{[category:{"a"}, category:{"b"}, category:{"c"}}... $scope.show(subcategory, category){ $scope.listOfDocuments=$scope.typeObj(subcategory, id);}

推荐答案

scope.show（子类别，类别）{ scope.show(subcategory, category){

scope.listOfDocuments = scope.listOfDocuments=

scope.typeObj（subcategory，id）;} scope.typeObj(subcategory, id);}
