In this small coding project, I experimented with a custom context menu, the list of options that pop up when you right click. It's simple JavaScript about detecting the event, get the cursor's current posistion, and then show the menu according to where the cursor is. The JavaScript code also handles the actual functions from the menu.
I will probably use this technique on my own web apps I'll hopefully finish developing in the future, because, come on, I can literally do anything with this awesome customized context menu!
Note: Because of security problems, inspect doesn't work. And what do you need to delete on this page?
