Question

我有两个清单。公司和员工。我有一个名为＆＃34; company＆＃34;在员工列表中，该列表指向员工的ID。

在我的REST查询中，我可以非常轻松地扩展公司的标题

http://abhi-sharepoint.abhishek.com/sites/dev/_api/web/lists/getbytitle('Employee')/items?$select=ID,Title,Company/Title&$expand=Company/Id&$filter=Company/Id%20eq%20%2714%27

非常好！

现在，我将另一个查找列添加到名为Manager的Employee List中，并将其指向employee id

现在我如何将ManagerId扩展为经理标题？

我试过

http://abhi-sharepoint.abhishek.com/sites/dev/_api/web/lists/getbytitle('Employee2')/items?$select=ID,Title,Employee2/Title,Company/Title&$expand=Company/Id&$expand=Manager/Id&$filter=Company/Id%20eq%20%2714%27

我也试过

http://abhi-sharepoint.abhishek.com/sites/dev/_api/web/lists/getbytitle('Employee2')/items?$select=ID,Title,Employee2/Title,Company/Title&$expand=Company/Id&$expand=Employee2/Id&$filter=Company/Id%20eq%20%2714%27

但没有任何作用。如何在同一列表中使用展开？

以下REST端点

/_api/web/lists/getbytitle('Employee')/items?$select=Title,Company/Title,Manager/Title&$expand=Company/Id,Manager/Id

返回Employee Title，Company Title和Manager Title，其中Manager字段是同一列表的Lookup

示例：

var query = "/_api/web/lists/getbytitle('Employee')/items?$select=Title,Company/Title,Manager/Title&$expand=Company/Id,Manager/Id";
$.ajax({
    url: _spPageContextInfo.webAbsoluteUrl + query,
    type: "GET",
    headers: { "ACCEPT": "application/json;odata=verbose" },
    success: function(data){
      $.each(data.d.results, function(idx,item){
          console.log(item.Title); //Employee Title
          console.log(item.Company.Title); //Company Title
          console.log(item.Manager.Title); //Manager Title
      });
    },
    error:  function(data){
      console.log(JSON.stringify(data));
    }
});

SharePoint REST查询展开自引用列
