Action Attribute

The Action Attribute

The action attribute defines the action to be performed when the form is submitted.

Usually, the form data is sent to a file on the server when the user clicks on the submit button.

In the example below, the form data is sent to a file called "action_page.php". This file contains a server-side script that handles the form data:

<!DOCTYPE html>
<html>
<body>

<h2>HTML Forms</h2>

<form method="get" action="/php/action_page.php">
  <label for="fname">First name:</label><br>
  <input type="text" id="fname" name="fname" value="Bintu"><br><br>
  <label for="lname">Last name:</label><br>
  <input type="text" id="lname" name="lname" value="Chaudhary"><br><br>
  <input type="submit" value="Submit">
</form> 

<p>If you click the "Submit" button, the form-data will be sent to a page called "/action_page.php".</p>

</body>
</html>

The Target Attribute

The target attribute can have one of the following values:

The default value is _self which means that the response will open in the current window.

<form method="get" action="/php/action_page.php" target="_blank">
  <label for="fname">First name:</label><br>
  <input type="text" id="fname" name="fname" value="Bintu"><br><br>
  <label for="lname">Last name:</label><br>
  <input type="text" id="lname" name="lname" value="Chaudhary"><br><br>

The Method Attribute using the GET method

The method attribute specifies the HTTP method to be used when submitting the form data.

The form-data can be sent as URL variables (with method="get") or as HTTP post transaction (with method="post").

The default HTTP method when submitting form data is GET.

<!DOCTYPE html>
<html>
<body>

<h2>The method Attribute</h2>

<p>This form will be submitted using the GET method:</p>

<form method="get" action="/php/action_page.php" target="_blank">
  <label for="fname">First name:</label><br>
  <input type="text" id="fname" name="fname" value="Bintu"><br><br>
  <label for="lname">Last name:</label><br>
  <input type="text" id="lname" name="lname" value="Chaudhary"><br><br>
  <input type="submit" value="Submit">
</form> 

<p>After you submit, notice that the form values is visible in the address bar of the new browser tab.</p>

</body>
</html>

The Method Attribute using the POST method

This example uses the POST method when submitting the form data:

<!DOCTYPE html>
<html>
<body>

<h2>The method Attribute</h2>

<p>This form will be submitted using the POST method:</p>

<form method="post" action="/php/actionPagePost.php" target="_blank">
  <label for="fname">First name:</label><br>
  <input type="text" id="fname" name="fname" value="Bintu"><br><br>
  <label for="lname">Last name:</label><br>
  <input type="text" id="lname" name="lname" value="Chaudhary"><br><br>
  <input type="submit" value="Submit">
</form>

The Autocomplete Attribute

The autocomplete attribute specifies whether a form should have autocomplete on or off.

When autocomplete is on, the browser automatically complete values based on values that the user has entered before.

<!DOCTYPE html>
<html>
<body>

<h1>The form autocomplete attribute</h1>

<p>Fill in and submit the form, then reload the page, start to fill in the form again - and see how autocomplete works.</p>

<p>Then, try to set autocomplete to "off".</p>

<form method="post" action="/php/actionPagePost.php" autocomplete="on">
  <label for="fname">First name:</label><br>
  <input type="text" id="fname" name="fname"><br><br>
  <label for="lname">Last name:</label><br>
  <input type="text" id="lname" name="lname"><br><br>
  <input type="submit" value="Submit">
</form> 

</body>
</html>

The Novalidate Attribute

The novalidate attribute is a boolean attribute.

When present, it specifies that the form-data (input) should not be validated when submitted.

<!DOCTYPE html>
<html>
<body>

<h1>The form novalidate attribute</h1>

<p>The novalidate attribute indicates that the form input is not to be validated on submit:</p>

<form method="post" action="/php/actionPagePost.php" novalidate>
  <label for="fname">First name:</label><br>
  <input type="text" id="fname" name="fname"><br><br>
  <label for="lname">Last name:</label><br>
  <input type="text" id="lname" name="lname"><br><br>
  <input type="submit" value="Submit">
</form>
