How to use the URL encoder & decoder.
Calculate and review
Use the main action when needed. Component mode uses encodeURIComponent and decodeURIComponent; full URL mode preserves structural URL characters.
Try a worked example
Encode a query value containing spaces and ampersands without changing the rest of a URL.
Check the assumptions
Form query strings often use + for a space, while general percent decoding does not automatically do so.
