What is URL Encoding?
URL encoding (also known as Percent-encoding) is a mechanism for safely transmitting information within a Uniform Resource Identifier (URI). Characters that are not strictly alphanumeric must be encoded to securely pass through HTTP structures without conflicts or errors. The encoded format represents unsafe characters as a "%" followed by two hexadecimal digits representing the character's ASCII/Unicode mapping.
encodeURI vs encodeURIComponent
- encodeURIComponent (Full Encoding): Use this when you are encoding a parameter value that goes into a query string. It escapes characters like
?, =, &, /. - encodeURI (Partial): Use this when you want a working URL but need to encode spaces and special characters. It leaves standard URL characters like
/, ?, :unescaped.
