window.close() 更新到 Django 4 后停止工作

Question

I updated packages in my project to latest version, and while testing in Firefox I encountered that window.open() assigned to variable returns Object - debugged with the code below:

let test = window.open($(e.currentTarget).attr('href'), '_blank', "height=640,width=480,toolbar=0,location=0,menubar=0");
console.log(test);

And, when I close test (this object) using .close() ( test.close() ) it works just fine, but after upgrading packages (django 3 to 4 version) it stopped working, and test variable returns Window , not Object .

I'm not really sure why it works that way, does Django 4 set some custom headers that cause the window close mechanism not work properly? How I should fix that?

Answer 1

Okey, I know how Django affects that.

It's because the browser context is not set and cause are the new security features. To ommit that, set the SECURE_CROSS_ORIGIN_OPENER_POLICY variable to None .
