About passing parameters back to the address bar

a page opens page b,

The

b page is a list. Click on the list item

take the content you clicked and go back to page a. How can this be achieved?

and how to retain the data filled in by the user on page a?

The

page is not separated from the front and rear, and there is no need for the framework to route these


I wonder if I understand whether to open the b page for the
a page. If you click on one of the contents of the b page, you will bring the clicked content and jump back to page a directly.
if this is the case, you can just write a click event, route jump, and route parameters.
