Can I implement record copying functionality in a portal?

[bonsai]

I would like to implement a function similar to copying an incident in a portal form widget.

I would like to use the field values ​​of the record currently being displayed and post them as the initial values ​​of the record producer.

Is this possible?

I think it would be possible if I could set dynamic initial values ​​for the record producer.

I was trying to implement a record copy function by cloning a link button widget.

The requirements were as follows:

- Place the widget on a form page.

- When the widget is clicked, the value of the form's "test_A" field is retrieved, and the field value is pasted into the record producer variable "TEST_A" and displayed.

I tried setting the following code in the custom widget's client controller.

However, the record producer was displayed with no initial value set.

Does anyone know a better way to do this?

 var url = '/sp?id=test_catalog_item&sys_id=xxxxxxxxxxxxxxxxxxxxxxxxxxxx(sys_id)&TEST_A="test";
		alert(url);
		//$location.url(url);
		window.location.href = url;

The script content is slightly different from the requirements, but it is trying to set a string to TEST_A for testing purposes.
This doesn't work...
