使用WebPart过滤器显示特定的列表项

问题描述：

我有一个列表，该列表会在添加项目后启动工作流程，然后我的工作流程会分配一些任务以供批准.

I have a List that initiates a workflow upon adding Items and then I have the workflow assigning some Tasks for approval purposes.

我想在任务批准"页面上显示启动工作流程的特定项目.

I would like to show the specific Item that initiated the workflow at the Task Approval page.

在寻找解决方案时，我找到了过滤器零件作为可能的解决方案， 已连接与列表，可以提取所需的列表项.

Searching for a solution I found as possible solution the Filter Parts that when connected with a list, the required list item could be extracted.

我尝试使用查询字符串(URL)过滤器，但是它不起作用.

I tried using the Query String (URL) Filter but it doesn't work.

我认为这与列表项的 ID 没有传递到任务页面有关.

I think it has to do with the ID of the List Item not being passed to the Task Page.

有人对此主题有知识吗?

Anyone with some klowledge on this subject?

答

作为一种解决方法，我们可以使用REST API以任务项形式获取ReletedItems字段.

As a workaround, we can get the ReletedItems field in task item form using REST API.

/_api/web/lists/getbytitle('MyTasks')/items(1)?

select = RelatedItems

select=RelatedItems

然后基于商品ID获取列表商品数据库，然后使用JavaScript代码在任务批准页面中添加一些信息.

Then get the list item data base on the item id, then add some information into the task approval page using JavaScript code.
