there are three pages, home page A, selection page B, and new page C;
route switching is all $router.push operation, and mode is the default hash
enter the selection page on the home page, and select the page to enter the new added page
A = > B = > C, click to return to C = > B = > A;
the home page goes to the selection page, the selection page goes to the new added page, the new page returns to the selection page successfully, then adds it again, and returns to the selection page again successfully
how do I click back to go directly to the A page at this time?
A = > B = > C = > B = > C = > C = > B
problem summary: as long as you are on the C page, the return is the B page; as long as you are on the B page, the return is the A page; as long as you are on the A page, the return is the empty page or the document.referer page
