javascript - SPServices.SPCascadeDropdowns 未正确级联

Question

我有三个 SharePoint 2016 列表:

• 组织
• 部门
• 团体

组按部门排序，部门按组织排序。

每个列表中的标题字段用于组、组织或部门的名称，每个列表中都有一个下拉列表来选择相应项目的父项。

在我的一个表单中，用户应该选择拥有特定软件名称的组织、部门和组。我正在尝试使用 SPServices.SPCascadeDropdowns 仅显示所选组织的部门，但它根本没有执行任何操作。

表单中的相关字段是:

<td valign="top" class="ms-formlabel">
  <H3 class="ms-standardheader">
    <nobr>Organization<span class="ms-formvalidation"> *</span></nobr>
  </H3>
</td>
<td valign="top" class="ms-formbody">
  <SharePoint:FormField runat="server" id="ff9{$Pos}" ControlMode="New"
   FieldName="Organization" 
   __designer:bind="{ddwrt:DataBind('i',concat('ff9',$Pos),'Value','ValueChanged','ID',ddwrt:EscapeDelims(string(@ID)),'@Organization')}"/>
  <SharePoint:FieldDescription runat="server" id="ff9description{$Pos}" FieldName="Organization" ControlMode="New"/>
</td>
<td valign="top" class="ms-formlabel">
  <H3 class="ms-standardheader">
    <nobr>Department<span class="ms-formvalidation"> *</span></nobr>
  </H3>
</td>
<td valign="top" class="ms-formbody">
  <SharePoint:FormField runat="server" id="ff10{$Pos}" ControlMode="New"
  FieldName="Department"
  __designer:bind="{ddwrt:DataBind('i',concat('ff10',$Pos),'Value','ValueChanged','ID',ddwrt:EscapeDelims(string(@ID)),'@Department')}"/>
  <SharePoint:FieldDescription runat="server" id="ff10description{$Pos}" FieldName="Department" ControlMode="New"/>
</td>

我使用的 Javascript 是:

$(document).ready(function(){
    $().SPServices.SPCascadeDropdowns({
        relationshipList: "{xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx}",
        relationshipListParentColumn: "Organization",
        relationshipListChildColumn: "Title",
        parentColumn: "Organization",
        childColumn: "Department",
        debug: true
    });
});

我已经加载了 jQuery 3.2.1 和 jQuery.SPServices-2014.02.min.js。我在 Chrome 控制台中没有收到任何错误，它只是什么也没做。如果我在 $().SPServices 处打断，它就会命中，所以我知道它正在被调用。知道我做错了什么吗？

考虑到你没有提供你的数据结构，我带来了我的;)

使用此 PowerShell 脚本在特定网站集中创建结构:

$web = get-spweb <YOUR URL>
$template = $web.ListTemplates | where name -eq 'Custom List'
$organizationsListId = $web.Lists.Add("Organizations", "", $template)
$departmentsListId = $web.Lists.Add("Departments", "", $template)
$groupsListId = $web.Lists.Add("Groups", "", $template)

$organizationsLookup = $web.Fields.AddLookup("OrganizationsLookup", $organizationsListId, $false)
$departmentsLookup = $web.Fields.AddLookup("DepartmentsLookup", $departmentsListId, $false)

$organizations = $web.Lists[$organizationsListId]
$departments = $web.Lists[$departmentsListId]
$groups = $web.Lists[$groupsListId]

$departments.Fields.Add($web.Fields.GetFieldByInternalName("OrganizationsLookup"))
$groups.Fields.Add($web.Fields.GetFieldByInternalName("DepartmentsLookup"))
$groups.Fields.Add($web.Fields.GetFieldByInternalName("OrganizationsLookup"))

$organizationsLookupInList = $departments.Fields.GetFieldByInternalName("OrganizationsLookup");
$organizationsLookupInList.LookupField = "Title"
$organizationsLookupInList.Update()

$departmentsLookupInList = $groups.Fields.GetFieldByInternalName("DepartmentsLookup");
$departmentsLookupInList.LookupField = "Title"
$departmentsLookupInList.Update()

$organizationsLookupInList1 = $groups.Fields.GetFieldByInternalName("OrganizationsLookup");
$organizationsLookupInList1.LookupField = "Title"
$organizationsLookupInList1.Update()

function AddListItem($list, $title)
{
    $itm = $list.AddItem()
    $itm["Title"] = $title 
    $itm.Update()
    return $itm
}

function AddListItemDepartments($list, $title, $lookupIdOrg)
{
    $itm = AddListItem $list $title
    $itm["OrganizationsLookup"] = $lookupIdOrg
    $itm.Update();
    return $itm
}

function AddListItemGroups($list, $title, $lookupIdOrg, $lookupIdDep)
{
    $itm = AddListItemDepartments $list $title $lookupIdOrg
    $itm["DepartmentsLookup"] = $lookupIdDep
    $itm.Update();
    return $itm
}

$org1Id = (AddListItem $organizations "AAA NET").ID
$org2Id = (AddListItem $organizations "BBB NET").ID
$org3Id = (AddListItem $organizations "CCC NET").ID
$org4Id = (AddListItem $organizations "DDD NET").ID


$dep1Id = (AddListItemDepartments $departments "Finance" $org1Id).ID
$dep2Id = (AddListItemDepartments $departments "IT" $org1Id).ID
$dep3Id = (AddListItemDepartments $departments "Finance" $org2Id).ID
$dep4Id = (AddListItemDepartments $departments "Social" $org2Id).ID
$dep5Id = (AddListItemDepartments $departments "Fun" $org2Id).ID
$dep6Id = (AddListItemDepartments $departments "Sport" $org2Id).ID
$dep7Id = (AddListItemDepartments $departments "Knowledge" $org3Id).ID
$dep8Id = (AddListItemDepartments $departments "Sport" $org3Id).ID

下一步:

1. 打开组列表新表单页面。
2. 点击右上角设置中的编辑页面。

3. 编辑 xsltlistviewformwebpart，将 jquery 和 spservices 附加到 JSLink 属性 即:

   ~site/siteassets/jquery-3.2.1.min.js | ~site/siteassets/jquery.SPServices-2014.02.min.js

4. 将 CEWP 添加到页面，将其移动到 webpart 下方并插入您的 js 级联下拉代码:

代码(见评论)

$(document).ready(function(){
    $().SPServices.SPCascadeDropdowns({
        relationshipList: "{xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx}", // Your departments list id
        relationshipListParentColumn: "OrganizationsLookup",
        relationshipListChildColumn: "Title",
        parentColumn: "OrganizationsLookup",
        childColumn: "DepartmentsLookup",
        debug: true
    });
});

这应该可以工作(也适用于 jquery 3.2.1)
