The Action Attribute

The action attribute portrays the action to be performed when the edge is submitted. 

Customarily, the shape data is sent to a web page on the server when the customer taps on the submit get. 

For the situation over, the edge data is sent to a page on the server called "/action_page.php". This page contains a server-side substance that handles the shape data:

<form action="/action_page.php">

The Target Attribute

The target attribute determines if the submitted result will open in another program tab, an edge, or in the present window. 

The default esteem is "_self" which implies the shape will be submitted in the present window. 

To influence the frame to come about open in another program tab, utilize the esteem "_blank":

Example

<form action="/action_page.php" target="_blank">

The Name Attribute

Each info field must have a name attribute to be submitted.
On the off chance that the name attribute is precluded, the data of that information field won't be sent by any stretch of the imagination.
This case will just present the "Last name" input field:

Example

<form action="/action_page.php">
  First name:<br>
  <input type="text" value="Mickey"><br>
  Last name:<br>
  <input type="text" name="lastname" value="Mouse"><br><br>
  <input type="submit" value="Submit">
</form>
