Delete all documents which have no parent when opening new form

I hope you can help me with this. I have included a library in my form.
However, if a document is uploaded and the form is not saved, the document is displayed again the next time the form is opened.
Is there a way to delete all existing documents without parent from this user the next time the form is opened?
I currently have a view that only shows all documents of a user.

Best regards

Hello @Sternchen,

You can delete document from the Document Library using PnPjs function:


You can delete all files that are displayed in List or Library control like so:

var docuemnts = fd.control('SPDataTable1');

docuemnts.forEach(doc => 

How can I intercept beforehand that it only executes when documents are there?
Currently I get the error message from undefined. For example, with users who open the form for the very first time. No documents can be displayed for them.
Even if there is a document there, this error message comes up.

I have used this code as suggested. However, the message with undefined always comes up.
What is the reason for this and how do I fix it?

Dear @Sternchen,
The control should be ready before it can be used to retrieve values, like this:

    fd.control('SPDataTable1').ready().then(function(dt) {
        var documents = fd.control('SPDataTable1');
        documents.forEach(doc => 

Thanks for the help.
The element is now deleted, but it is still displayed.

I added this after your function.


Seems like it is working. Do you have another idea instead of the refresh?

Dear @Sternchen,
No, it's good, especially if it's working :slight_smile: My code was just to delete documents, but yes, you need to refresh the control to see the results.

Thank you for your help. :slight_smile:
