Part of my computer science project is making a multiple choice radio button quiz in HTML, and I’ve already done that. Now the part we have to do now is to make the quiz actually work with javascript. We’re supposed to have a submit button that when clicked, displays how many questions you got correct. Help please?
Here’s my code for the quiz (non-working). It’s basically a giant list with forms being the list items.
Including comments would be helpful.
