I'm working with a website that has a button implemented as an anchor element, but it doesn't have an href attribute. When I click this button, it triggers a JavaScript event that starts a download. Is there a way to trigger that JavaScript event manually from the developer tools console without actually clicking the button?

If your main goal is to trigger the download without clicking the button, you'll probably need to execute the method behind it directly. However, if it's specifically for downloads, browsers often need a user action like a button click. Still, you might try opening the link in a new window to see if that works!
One quick way to do this is to check if the event or method is accessible through the window object. If it is, you can just call it directly from the console! That way, no need for the click at all.
You could also consider running the event immediately when the page loads—or after a slight delay. The button might seem unnecessary if the download event can be triggered programmatically, although you'll want to keep in mind that some browsers might require a user interaction for downloads.
You can use this command in the console: document.querySelector('a selector that finds the button').dispatchEvent(new Event('click')); This simulates the button click via JavaScript and should trigger the download. Just make sure your selector targets the right element!
