I have many buttons with ID attribute.

<button id="some_id1"></button> <button id="some_id2"></button> <button id="some_id3"></button> <button id="some_id4"></button> <button id="some_id5"></button> 

Assume the user clicks on some button, and I want to alert this ID of the button the user just clicked on.

How can I do this via JavaScript or jQuery?
