The form Attribute
The input form attribute determines the form the <input> element belongs to.
The value of this attribute must stand equal to the id attribute of the <form> element it belongs to.
Example
An input field found outside of the HTML form (but still a part of the form):
<!DOCTYPE html><html><body><h1>The input form attribute</h1><p>The form attribute specifies the form an input element belongs to.</p><form action="/action_page.php" id="form1"><label for="fname">First name:</label><input type="text" id="fname" name="fname"><br><br><input type="submit" value="Submit"> </form><p>The "Last name" field below is outside the form element, but still part of the form.</p><label for="lname">Last name:</label><input type="text" id="lname" name="lname" form="form1"></body></html>{codeBox}
The formaction Attribute
The input formaction attribute determines the URL of the file that will process the input when the form is submitted.
Notice: This attribute overrides the action attribute of the <form> element.
The formaction attribute functions with the following input types: submit and image.
Example
An HTML form with two submit buttons, with different actions:
<form action="/action_page.html"><label for="fname">First name:</label><input type="text" id="fname" name="fname"><br><br><label for="lname">Last name:</label><input type="text" id="lname" name="lname"><br><br><input type="submit" value="Submit"><input type="submit" formaction="/action_page2.html" value="Submit as Admin"></form>{codeBox}
The formenctype Attribute
The input formenctype attribute determines how the form-data should be encoded when submitted (only for forms with method="post").
Notice: This attribute overrides the enctype attribute of the <form> element.
The formenctype attribute functions with the following input types: submit and image.
Example
A form with two submit buttons. The first sends the form-data with default encoding, the second sends the form-data encoded as "multipart/form-data":
<form action="/action_page_binary.html" method="post"><label for="fname">First name:</label><input type="text" id="fname" name="fname"><br><br><input type="submit" value="Submit"><input type="submit" formenctype="multipart/form-data"value="Submit as Multipart/form-data"></form>{codeBox}
The formmethod Attribute
The input formmethod attribute specifies the HTTP method for sending form-data to the action URL.
Notice: This attribute overrides the method attribute of the <form> element.
The formmethod attribute functions with the following input types: submit and image.
The form-data can be transmitted as URL variables (method="get") or as an HTTP post transaction (method="post").
Notes on the "get" method:
- This process appends the form-data to the URL in name/value pairs.
- This approach is good for form submissions where a user desires to bookmark the result.
- There is a limitation to how much data you can place in a URL (varies between browsers); therefore, you cannot be confident that all of the form-data will be perfectly transferred.
- Never use the "get" way to pass sensitive details! (password or other sensitive information will be visible in the browser's address bar)
Notes on the "post" method:
- This process sends the form-data as an HTTP post transaction
- Form submissions with the "post" process cannot be bookmarked
- The "post" process is more robust and safe than "get", and "post" does not have size limitations
Example
A form with two submit buttons. The first sends the form-data with method="get". The second sends the form-data with method="post":
<!DOCTYPE html><html><body><h1>The input formmethod Attribute</h1><p>The formmethod attribute defines the HTTP method for sending form-data to the action URL.</p><form action="/action_page.html" method="get" target="_blank"><label for="fname">First name:</label><input type="text" id="fname" name="fname"><br><br><label for="lname">Last name:</label><input type="text" id="lname" name="lname"><br><br><input type="submit" value="Submit using GET"><input type="submit" formmethod="post" value="Submit using POST"> </form></body></html>{codeBox}
The formtarget Attribute
The input formtarget attribute determines a name or a keyword that indicates where to show the response that is received after submitting the form.
Notice: This attribute overrides the target attribute of the <form> element.
The formtarget attribute functions with the following input types: submit and image.
Example
A form with two submit buttons, with different target windows:
<form action="/action_page.html"><label for="fname">First name:</label><input type="text" id="fname" name="fname"><br><br><label for="lname">Last name:</label><input type="text" id="lname" name="lname"><br><br><input type="submit" value="Submit"><input type="submit" formtarget="_blank" value="Submit to a new window/tab"></form>{codeBox}
The formnovalidate Attribute
The input formnovalidate attribute determines that an <input> element should not be validated when submitted.
Notice: This attribute overrides the novalidate attribute of the <form> element.
The formnovalidate attribute functions with the following input types: submit.
Example
A form with two submit buttons (with and without validation):
<form action="/action_page.html"><label for="email">Enter your email:</label><input type="email" id="email" name="email"><br><br><input type="submit" value="Submit"><input type="submit" formnovalidate="formnovalidate" value="Submit without validation"></form>{codeBox}
The novalidate Attribute
The novalidate attribute is a <form> attribute.
When present, novalidate determines that all of the form-data should not be validated when submitted.
Example
Specify that no form-data should be validated on submit:
<!DOCTYPE html><html><body><h1>The form novalidate attribute</h1><p>The novalidate attribute specifies that the form data should not be validated when submitted.</p><form action="/action_page.html" novalidate><label for="email">Enter your email:</label><input type="email" id="email" name="email" required><br><br><input type="submit" value="Submit"> </form><p><strong>Note:</strong> The novalidate attribute of the form tag is not supported in Safari 10 (or earlier).</p></body></html>{codeBox}
