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:
EXAMPLE:
<form action="/action_page.php">
<label for="fname">First name:</label><br>
<input type="text" id="fname" name="fname" value="John"><br>
<label for="lname">Last name:</label><br>
<input type="text" id="lname" name="lname" value="Doe"><br><br>
<input type="submit" value="Submit">
</form>
The Target Attribute
The target attribute specifies where to display the response that is received after submitting the form.
The target attribute can have one of the following values:
EXAMPLE:
<form action="/action_page.php" target="_blank">
The Method Attribute
The method attribute specifies the HTTP method to use 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.
EXAMPLE:
<form action="/action_page.php" method="get">
EXAMPLE:
<form action="/action_page.php" method="post">
Notes on GET:
- Appends the form data to the URL, in name/value pairs
-NEVER use GET to send sensitive data! (the submitted form data is visible in the URL!)
- The length of a URL is limited (2048 characters)
- Useful for form submissions where a user wants to bookmark the result
- GET is good for non-secure data, like query strings in Google
Notes on POST:
- Appends the form data inside the body of the HTTP request (the submitted form data is not shown in the URL)
- POST has no size limitations, and can be used to send large amounts of data
- Form submissions with POST cannot be bookmarked
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.
EXAMPLE:
<form action="/action_page.php" autocomplete="on">
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.
EXAMPLE:
<form action="/action_page.php" novalidate>
