The form-data is sent to the page specified in the action attribute. The form-data can be sent as URL variables (with method="get") or as HTTP post transaction (with method="post").
The method attribute can be used on the <form> element.
<form method="get | post"></form>
get: default; appends the form-data to the URL in name/value pairs: URL?name=value&name=value.
In the "get/GET" method, after the submission of the form, the form values will be visible in the address bar of the new browser tab. It has a limited size of about 3000 characters. It is only useful for non-secure data, not for sensitive information.
post: sends the form-data as an HTTP post transaction.
In the "post/POST" method, after the submission of the form, the form values will not be visible in the address bar of the new browser tab as it was visible in the GET method. It appends form data inside the body of the HTTP request. It has no size limitation. This method does not support bookmark the result.
