Error: The usage of document is invalid in this context (Typescript)

Whenever I attempt to utilize TypeScript, the error message "ReferenceError: document is not defined" keeps popping up while using document.getElementByID();.

Can someone please advise on how to resolve this issue?

Answer №1

When the document is possibly undefined, we must take precautions.

To keep TypeScript happy, use a guard statement like this:

if (document) document.getElementById();

By ensuring that document exists before calling getElementById(), we avoid potential errors where document could be undefined.
