是否可以从单独的html页面单击html页面上的按钮？

Question

I have two custom html pages: 'first.html' and 'second.html'. In 'second.html' I have a hidden div. I want to click a button on 'first.html' that will unhide the div in 'second.html'. I want both pages to be open at the same time in different windows/tabs.

This is a Django project so I tried to create a def in views.py that will open 'second.html' when the button on 'first.html' is opened. Doing this will just open 'second.html', but I need both pages to be opened at the same time.

This sounds a bit weird, but sure. I can think of two ways to do it:

1. Have first.html open second.html using window.open() . This gives first.html full access to the DOM of second.html .

2. Communicate through the server. first.html tells the server the button has been clicked. second.html is listening, maybe with EventSource and updates it's DOM.
