Real-world Scenarios
Safely encode special characters or spaces in parameters when calling REST APIs to prevent errors.
Convert search terms containing special characters into standard format for URL query strings.
Escape special characters when including URLs directly in HTML href attributes to avoid syntax errors.
Convert characters not allowed in URLs into safely transmittable format when sending data via GET requests.
Pro Tips
encodeURI preserves URL structure while encodeURIComponent converts all special characters. Use encodeURIComponent for parameter values.
Spaces are typically converted to %20 in URLs, but may become + in application/x-www-form-urlencoded format.
Alphabets, numbers, hyphens (-), underscores (_), periods (.), and tildes (~) remain unencoded.
Multi-byte characters are converted to UTF-8 byte sequences first, then each byte is encoded as %XX.
