Function introduction

1. Use JavaScript's encodeURI and encodeURIComponent for encoding.
2. Use JavaScript's decodeURIComponent to decode.

Method Introduction

encodeURI

• Purpose: Used to encode the entire URI. For example: "http://example.com/This is a test? name= Zhang San ".
• Encoding rules: Only characters with special meaning in the URI will be encoded, such as spaces (encoded as %20),#(encoded as %23), etc. The following characters will not be encoded: A-Z,a-z,0-9,-,_,.!,~,*, '、(、)、;、/、?、:、@、&、=、+、$、,`，Because these characters have a specific meaning in the URI.

encodeURIComponent

• Purpose: Used to encode part of the URI (such as the values of query parameters), rather than the entire URI. For example: "name= Zhang San &age=25".
• Encoding rules: encodeURIComponent encodes all non-alphanumeric characters, including ;,/,?:,@,&,=,+,$,,, etc., because these characters have no special meaning in the URI component, they are all encoded.

decodeURIComponent

• Purpose: Used to decode individual URI components (such as the values of query parameters) and restore the characters encoded by encodeURIComponent to the original characters.
• Decoding rules: decodeURIComponent will decode all characters encoded by encodeURIComponent and convert the encoding starting with % back to the corresponding character. For example,%20 will be decoded as spaces, and %3D will be decoded as =.
