If my html has nested structure like



Assuming there is only ONE elemet whose id is called "myinput" (no ambiguity), does

document.getElementById("myinput") work ?

or should we do

document.getElementById("div1").getElementById("div2").getElementById("myinput")


I found sometimes it works using the first one but sometimes it doesn't.

please help explain. thanks

In any document all id values need to be unique. If they are not, the document is invalid and all bets are off.

does document.getElementById("myinput") work ?

Yes. For valid documents.

or should we do

Never.
