How to access object properties containing special characters?

I have a form DOM element:

var virDom = document.getElementsByTagName("form")[0];

virDom has two fields with IDs creditId and pwdId... I can access virDom.creditId without any issue but, virDom.pwdId.. is failing with a syntax error, because of the periods contained in the name.

How can I access such properties?



Use bracket notation:


This applies to any object, and it is particularly useful for non-identifier-safe characters and also for accessing keys that you may not know ahead of time.
