chaining getElementById

Question

I\'ve been looking for an answer to this question but I could find none so I thought I\'d try StackOverflow.

In javascript, is this valid:

x = document

Answer 1

Consider not using id when there are more than one

Maybe a class or custom attribute is better, you can then use document.querySelectorAll to fins them.

els = document.querySelectorAll('[custom-attr]')
