JavaScript - Methods GET vs. POST in HTML forms 

The GET method in the HTML forms passes the form values by setting the URL.

Eg: If you type the word ‘Hello’ in Google Search, it sets the following URL:

http://www.google.co.in/search?hl=en&q=hello&btnG=Search&meta=&aq=f&oq=

The POST method sends the data to the server without setting the URL:

Eg:
-----------------------------97891525516423
Content-Disposition: form-data; name="username"

aaaa
-----------------------------97891525516423
Content-Disposition: form-data; name="password"

bbbbb12345
-----------------------------97891525516423
Content-Disposition: form-data; name="submit"

Submit
-----------------------------97891525516423--
