Reply To: 1.4.6 – Event Propagation – Simple question about .id

[Zac Gordon]

Actually,

this.id

is shorthand for

this.getAttribute( 'id' )

documentGetElementById( ‘X’ ) will select an element on the page with an ID assigned of ‘X’. Once you get that value, .id would give you the value X.

So something like this:

var el = document.getElementById( 'content' ); 

console.log( el.id ); // Prints 'content'

Hope that helps! Good question 🙂
