HTML form submission method

HTML form submission method: two attributes, action and method, which are 5-heavy

 

 

 

(1) The action attribute specifies the program that processes the current form after it is submitted. This handler can be any dynamic web page.

 

 

 

 

(2) The method attribute specifies the form submission method. It has two possible values: get and post.

 

1. get and post have the following differences:

 

1. parameter names and parameter values are displayed in the address bar of the form submitted in get mode, but not in post mode. The parameters submitted in post mode are more confidential and safer.

2. Because the maximum number of bytes that can be entered in the address bar of the browser is limited, you cannot use the get method to submit a form with a larger parameter value. The post method does not have this restriction.
