SharePoint JavaScript 顯示來自查找字段的值

Question

Existing system has HTML, JavaScript forms with the following: SharePoint List, "CustomerType" with values SharePoint List, "Customer" with lookup column named, "CustomerType" pulling values from "CustomerType"

需要添加一個新字段，所以我通過創建鏡像“CustomerType”：SharePoint 列表，“CustomerSegmentation”，值為 SharePoint 列表，“客戶”，查找列名為“CustomerSegmentation”，從“CustomerSegmentation”中提取值

我復制了 HTML、JavaScript 等 - 在“客戶”列表中選擇一個值和創建項目都很好。 但是，當我嘗試在“顯示”HTML 表單上顯示所選值時，使用：

                    var CustomerSegmentationField = oListItem.get_item('CustomerSegmentationField');
            if (checkNotEmpty(CustomerSegmentationField)) {
                $("#selCustomerSegmentationField").val(CustomerSegmentationField.get_lookupId());
            }

我收到此錯誤：未捕獲錯誤：屬性或字段尚未初始化。 它尚未被請求或請求尚未執行。 可能需要明確要求。 at Function.Error.create (ScriptResource.axd?d=k5RfMmPNK2hWIceXJ8-ajx3E8J_9Fwh_cmdsa2b8w5b_6SdxoV5CP7PTQYU2geZFptqlColfo4USOXQsdBih3W0VS_49yn_5vEAL69UdI91yC-tDiYJ5qy_HJzfGk6ituovIGh_kYQ43NWRInP8bleYrT4aM9uWrD_zUrKaOdVSegfYI0_gHDDpmP74zGEwh0&t=ffffffffecf19baa&ctag=200622:formatted:177) at SP.ListItem.$1D_2 (sp.js:formatted:15164) at SP.ListItem.get_item ( sp.js:formatted:14868) 在 onQuerySucceeded (Display-New-Request.aspx?itemID=9076:1678) 在陣列。 (ScriptResource.axd?d=k5RfMmPNK2hWIceXJ8-ajx3E8J_9Fwh_cmdsa2b8w5b_6SdxoV5CP7PTQYU2geZFptqlColfo4USOXQsdBih3W0VS_49yn_5vEAL69UdI91yC-tDiYJ5qy_HJzfGk6ituovIGh_kYQ43NWRInP8bleYrT4aM9uWrD_zUrKaOdVSegfYI0_gHDDpmP74zGEwh0&t=ffffffffecf19baa&ctag=200622:formatted:23) at ScriptResource.axd?d=k5RfMmPNK2hWIceXJ8-ajx3E8J_9Fwh_cmdsa2b8w5b_6SdxoV5CP7PTQYU2geZFptqlColfo4USOXQsdBih3W0VS_49yn_5vEAL69UdI91yC-tDiYJ5qy_HJzfGk6ituovIGh_kYQ43NWRInP8bleYrT4aM9uWrD_zUrKaOdVSegfYI0_gHDDpmP74zGEwh0&t=ffffffffecf19baa&ctag=200622:formatted:2555 at SP.ClientRequest.$3K_0 (sp .runtime.js:2) 在數組中。 (ScriptResource.axd?d=k5RfMmPNK2hWIceXJ8-ajx3E8J_9Fwh_cmdsa2b8w5b_6SdxoV5CP7PTQYU2geZFptqlColfo4USOXQsdBih3W0VS_49yn_5vEAL69UdI91yC-tDiYJ5qy_HJzfGk6ituovIGh_kYQ43NWRInP8bleYrT4aM9uWrD_zUrKaOdVSegfYI0_gHDDpmP74zGEwh0&t=ffffffffecf19baa&ctag=200622:formatted:23) at ScriptResource.axd?d=k5RfMmPNK2hWIceXJ8-ajx3E8J_9Fwh_cmdsa2b8w5b_6SdxoV5CP7PTQYU2geZFptqlColfo4USOXQsdBih3W0VS_49yn_5vEAL69UdI91yC-tDiYJ5qy_HJzfGk6ituovIGh_kYQ43NWRInP8bleYrT4aM9uWrD_zUrKaOdVSegfYI0_gHDDpmP74zGEwh0&t=ffffffffecf19baa&ctag=200622:formatted:2555 at Sys.Net.WebRequest.completed ( ScriptResource.axd?d=k5RfMmPNK2hWIceXJ8-ajx3E8J_9Fwh_cmdsa2b8w5b_6SdxoV5CP7PTQYU2geZFptqlColfo4USOXQsdBih3W0VS_49yn_5vEAL69UdI91yC-tDiYJ5qy_HJzfGk6ituovIGh_kYQ43NWRInP8bleYrT4aM9uWrD_zUrKaOdVSegfYI0_gHDDpmP74zGEwh0&t=ffffffffecf19baa&ctag=200622:formatted:4336)

這包括那部分嗎？

Answer 1

該錯誤提到您尚未加載該字段。

確保您加載了項目並且字段 static 名稱與“CustomerSegmentationField”匹配

clientContext.load(listItem);    
clientContext.executeQueryAsync(Function.createDelegate(this, this.OnLoadSuccess), Function.createDelegate(this, this.OnLoadFailed));
