How Can I Access JavaScript Object Properties with Special Characters in Their Names?

Accessing Object Properties with Special Characters

In JavaScript, accessing an object's properties using dot notation can be problematic when the property names contain special characters, such as periods. This issue arises when attempting to access properties with the dot notation, as seen in the example below:

var virDom = document.getElementsByTagName("form")[0];
virDom.creditId; // Successful access
virDom.pwdId..; // Syntax error

Utilizing Bracket Notation

To effectively access such properties, bracket notation should be employed. This notation involves enclosing the property name within square brackets:

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

Bracket notation is applicable to any object and proves beneficial when dealing with non-identifier-safe characters and accessing keys that may not be known in advance. By adhering to this approach, you can seamlessly access object properties regardless of their characters, ensuring the smooth execution of your code.
