OpenStudy (dangerousjesse):
How do you make an onbeforeupload event actually work when you're writing a script? I can make text, links, and photos appear when I edit pages, but I can't make events occur when I want them to. Is there a "blank slate" website I can use to practice on, or do I have to use JavaScript?
OpenStudy (e.mccormick):
As far as I can tell, that is JS. So yes, JS would be needed for a JS line of code to work. https://developer.mozilla.org/en-US/docs/Web/API/Window.onbeforeunload
