Answer 1

you can use getAttribute & setAttribute methods

for example

document.getElementById('element').getAttribute('id')
document.getElementById('element').setAttribute('id', 'newId')

Answer 2

You can use document.getElementById('element').getAttribute('id'). When the attribute not exists you will get a null.

So you can check later whether the attribute exists.

if (document.getElementById('element').getAttribute('id') !== null) {
   // continue
}
