How can I check if my Element ID has focus? [duplicate]

Compare document.activeElement with the element you want to check for focus. If they are the same, the element is focused; otherwise, it isn't.

// dummy element
var dummyEl = document.getElementById('myID');

// check for focus
var isFocused = (document.activeElement === dummyEl);

hasFocus is part of the document; there's no such method for DOM elements.

Also, document.getElementById doesn't use a # at the beginning of myID. Change this:

var dummyEl = document.getElementById('#myID');

to this:

var dummyEl = document.getElementById('myID');

If you'd like to use a CSS query instead you can use querySelector (and querySelectorAll).

Use document.activeElement

Should work.

P.S getElementById("myID") not getElementById("#myID")

If you want to use jquery $("..").is(":focus").
