如何使用odata json更新外鍵

Question

預期行爲：用戶單擊註冊按鈕並在相關實體中創建記錄。直到現在，這一直髮展到現在，但現在我們需要根據當前表單上的查找來更新外鍵。我該如何做到這一點？下面的粘貼代碼會在瀏覽器中產生錯誤「創建記錄時出錯;錯誤 - 錯誤請求」

// JScript source code 
CreateButton = function() { 
    var fieldTable = crmForm.all.new_registerbutton_d; 
    var html = "<TABLE border=0 cellSpacing=0 cellPadding=0><TBODY><TR><TD width=0px>" + fieldTable.innerHTML + "</TD><TD width=200><INPUT style='BACKGROUND-COLOR: #d8e8ff' onclick=Button_OnClick() value='Register' type=button></TD></TR></TBODY></TABLE>"; 

    fieldTable.innerHTML = html; 
    document.all.new_registerbutton.style.display = 'none'; 
    crmForm.all.new_registerbutton_c.innerText = "";

已解決。區分大小寫。對new_new_se_invitation_new_se_registId使用了錯誤的大小寫。

var new_se_registration = { 

    new_new_se_invitation_new_se_regist**I**d: { 
    __metadata: { type: "Microsoft.Crm.Sdk.Data.Services.EntityReference" }, 
    Id: invitationGUID, 
    LogicalName: invitationName 
    }, 

    new_name: invitationName, 
    new_eventname: eventname 
};
