Question

I am displaying a confirm box in my app. When the user clicks on Okay, I close the window
when user clicks on Cancel, I want to do nothing but stay on the same page.

What should I write in place of DO_NOTHING?

    <a href="#" onclick="confirm('Do you wan to close the application ?')?window.close():DO_NOTHING')">Close the application ?</a> 

If I keep it empty it does not work. If I write any random string it works but displays string undefined error.

Answer 1

Just have this instead:

onclick="if (confirm('Do you wan to close the application ?')) window.close();"

No point of using the x?y:z if you don’t intend to use it “fully”.
