HTML Form Attribute
HTML forms use various attributes to define their behavior and appearance. Here’s an overview of some key form attributes and examples of how they’re used:
1. action
Description: Specifies the URL where the form data will be sent when the form is submitted.
Example:
<form action="submit_form.php" method="post">
<!-- Form fields go here -->
</form>
2. method
Description: Specifies the HTTP method to be used when submitting the form. Common values are get and post.
GET: Sends data in the URL query string.POST: Sends data in the request body.
Example:
<form action="submit_form.php" method="post">
<!-- Form fields go here -->
</form>
3. enctype
Description: Specifies how the form data should be encoded when submitted to the server. Used with POST method only. Common values are application/x-www-form-urlencoded, multipart/form-data, and text/plain.
Example:
<form action="submit_form.php" method="post" enctype="multipart/form-data">
<input type="file" name="fileUpload">
<input type="submit" value="Upload">
</form>
4. target
Description: Specifies where to display the response after submitting the form. Common values are _self, _blank, _parent, and _top.
Example:
<form action="submit_form.php" method="post" target="_blank">
<input type="submit" value="Submit">
</form>
5. name
Description: Assigns a name to the form, which can be used for scripting and referencing the form in JavaScript.
Example:
<form name="myForm" action="submit_form.php" method="post">
<input type="text" name="username">
<input type="submit" value="Submit">
</form>
6. autocomplete
Description: Controls whether the browser should automatically complete the fields. Values can be on or off.
Example:
<form action="submit_form.php" method="post" autocomplete="off">
<input type="text" name="username">
<input type="submit" value="Submit">
</form>
7. novalidate
Description: Prevents the browser from validating the form data when submitted.
Example:
<form action="submit_form.php" method="post" novalidate>
<input type="text" name="username" required>
<input type="submit" value="Submit">
</form>
8. accept-charset
Description: Specifies the character encodings that the server should accept. Useful for internationalization.
Example:
<form action="submit_form.php" method="post" accept-charset="UTF-8">
<input type="text" name="username">
<input type="submit" value="Submit">
</form>
