About HTML table unit details (1)

HTML form is used to collect user input;

Form element defines the HTML form.

 <FORM> Form Elements </form>

The action definition of the action attribute is performed when submitting the form.

The usual way to submit a form to the server is to use the submission button.

Generally, the form is submitted to the webpage on the web server.

If the action attribute is omitted, the action will be set to the current page

The METHOD attribute specifies the HTTP method (GET or Post) used when submitting a form:: Get or Post):

You can use get (default method):

If the form submission is passive (such as search engine query) and there is no sensitive information.

When you use Get, the form data is visible in the page address bar: action.jsp? Name = xxxx & sex = female

*PS: GET is most suitable for the submission of a small amount of data. The browser sets the capacity limit.

You should use post:

If the form is updating the data, or contains sensitive information (such as a password).

POST's security is even more secure, because the data submitted in the page address bar is not visible.
