How to Access Object Properties with Special Characters in JavaScript?

Accessing Object Properties with Special Characters

Accessing object properties with special characters, such as periods or other non-identifier-safe characters, can pose a challenge in programming. Consider the following scenario:

Problem:

You have an HTML form element with fields identified by complex IDs, such as "creditId" and "pwdId..". While accessing "creditId" is straightforward, accessing "pwdId.." using the conventional dot notation (e.g., virDom.pwdId..) results in a syntax error.

Solution:

To overcome this issue, utilize bracket notation when accessing object properties. Bracket notation allows access to properties with special characters:

virDom['creditId']
virDom['pwdId..']

This technique is particularly useful for non-identifier-safe characters (e.g., spaces, hyphens) and accessing keys that may not be known ahead of time. Remember that bracket notation can be applied to any object, not just HTML DOM elements.
