2.1, encodeURIComponent:

return value

A copy of the uristring, where some of the characters will be replaced by a hexadecimal escape sequence.

Description

The method does not encode ASCII letters and numbers, nor does it encode these ASCII punctuation marks:-_. ! ~ * ' ().

Other characters (such as:;/?:@&=+$,# These punctuation marks used to separate the URI component) are replaced by one or more hexadecimal escape sequences.

Hints and Notes

Tip: Note the difference between the encodeURIComponent () function and the encodeURI () function, which assumes that its arguments are part of a URI (such as a protocol, hostname, path, or query string). Therefore, the encodeURIComponent () function escapes punctuation marks that are used to separate the various portions of the URI.

2.2, encodeURI:

return value

A copy of the uristring, where some of the characters will be replaced by a hexadecimal escape sequence.

Description

The method does not encode ASCII letters and numbers, nor does it encode these ASCII punctuation marks:-_. ! ~ * ' ().

The purpose of this method is to fully encode the URI, so the encodeURI () function is not escaped for the following ASCII punctuation mark with a special meaning in the URI:;/?:@&=+$,#

Hints and Notes

Tip: If the URI component contains delimiters, such as? and #, each component should be encoded using the encodeURIComponent () method.
