使用 Ajax 时如何在自定义列表上显示查找字段

Question

I have a script that calls a custom list and displays information to the SharePoint page. I'm able to get the information, but not able to display the Section attribute. Section is an object. Section is a Lookup to another custom list on my site. Here is my code:

$(document).ready(function() {    
    loadItems();    
});    

function loadItems() {    
          console.log("loadItems ...");
    var siteUrl = _spPageContextInfo.siteAbsoluteUrl;    
    var oDataUrl = siteUrl + "/_api/web/lists/getbytitle('Contacts')/items?$select=Title,Organization,Section/Title,Business_x0020_Phone,Created&$expand=Section";    
    $.ajax({    
        url: oDataUrl,    
        type: "GET",    
        dataType: "json",    
        headers: {    
            "accept": "application/json;odata=verbose"    
        },    
        success: mySuccHandler,    
        error: myErrHandler    
    });    
}    

function mySuccHandler(data) {    
    try {    
          console.log("Success loading");

        $('#table_id').DataTable({    

            "aaData": data.d.results,    
            "aoColumns": [  
            {    
                "mData": "Title"    
            },   
            {    
                "mData": "Organization"    
            },   
            {    
                "mData": "Section"    
            },   
            {    
                "mData": "Business_x0020_Phone"    
            },  
            {    
                "mData": "Created"    
            }             
            ]    
        });    
    } catch (e) {    
        alert(e.message);    
    }    
}

function myErrHandler(data, errMessage) {    
    console.log("Error: " + errMessage);    
}

What should the syntax be for displaying the Section?

Answer 1

For Objects, I need to use the following syntax:

{    
    "mDataProp": "Section.Title"    
}

Instead of

{    
    "mData": "Section"    
}
